Kieran

buddy they should not be more than 2.50 for a complete race.

If you let me know what size you need i can procure some.

Kieran

How did you go.

I got there 10 minutes late so no race for me.

Kieran

who is going to the pudding race aka bike bug 500 ???

Kieran

20 to 30 mins buddy.

Kieran

it is fast, but there is plenty of opportunity to hide in a big pack if you so wish.

Re riding, i want to start doing regular evening rides at centennial, say till 7.30pm, then ride back to marrickville. perhaps thurdays would be a good day as gived a break before weekend racing etc.

Kieran

Kieran, what's your view on AC420's hub reliability? Are you confident that they've fixed that problem for good? The rear hub is good now, even the first ones you just needed to swap out a part. plus, unlike other wheels with alloy freehub body AC have a deeper spline and steel spacers to save the ...

Kieran

Anyone want to do the tuesday daylight savings crit racing. starts 6.00 at heffron.

3 grades handicap race, quite fact,- c grade is 40kph average or so.

always a very big pack and good prizes.

i think i will go next week for sure.

Kieran

thanks for the great report James.

Agreed we must train more for next year.

Kieran

It all depends on price really. Mavic are a good wheel, but they are also very pricey for what you get performance wise. A Ksyrium SL is still just an alloy box rim with bladed spokes, not even that light really. I think you really pay for the name. Check out the American Classic 420 wheels, they ar...

Kieran

Weel i think yoiu need a closed circuit.

Centennial park would be good.

Or, centennial, then via road to Tempe, last laps on the velodrome ala roubaix.

Kieran

This is brilliant, can we start a chariot race?

Kieran

Thats bad news, hope you get back on the bike soon, or trainer sooner. monday and wed I banged out a good 60 k or so at centennial in the arvo, pretty relaxing when you get a bunch to bludge off. Mornings i am not so keen on, as sleep is king. Even workers can ride in the early morning, but only ver...

Kieran

Buddy uni is over for the year for me so most weekdays i am free.

I like in marrickville so pretty easy to meet up.

Kieran

Sorry buddy, 32 hole front and rear, with the deep rim they are bulletprooof.

A am able to provide warranty and service too for these- should be 12 month but happy to help out if any probs any time.

Kieran

Okay, I am 90% certain for this one.

Kieran

RRP is $550, note they are for 8,9,10 speed cassete, front and rear.

If you want i have a slightly used ultegra 10 speed cassete to suit, included with wheels.

The wheels are completely new, in the box.

Kieran

Long story but I have aquired a nice set of Velocity Deep V road wheels, black rim, spokes and black formula hub, with QR skewers.

Having no use for them, I need to get rid of them. $350 for the pair if anyone wants them.

Kieran

Whats next on the calendar ???

Kieran

Does that mean they are not as stiff? Have you ever test ridden one before? possibly, i havent ridden them. In general three things will determine stiffness, cross section width, material thickness and the young's modulus of the material. the lenticular shape on most discs is for aerodynamics. But ...

Kieran

It is because they don't use a mould to get the shape. It is a honeycome core with two flat sheets of carbon bonded onto either side. The alloy rim and hib are just glued on as well. The moulds are very expensive to produce and require capital intensive machinery to use. You can see details of the p...

Kieran

It may be a Renn disc, they are completely flat, not lenticular at all.

Soon ypu can see one in person, as i have aquired one.

Kieran

whoops, i meant the P3C track frame- bb drop is 60mm.

Kieran

On closer inspection, I realised that the bb height on cervelo TT bikes is the same as the P2C, which is listed as a sprint capable frame, all are at 60mm bb drop. Many road models are 70mm.

If the P2C can be used in scratch races with shortish cranks then i should be right.

Kieran

Well I have managed to aquire another Cervelo TT frame on the cheap, ($400 with seatpole, seat, forks etc.) and have nice wheels a plenty. I was thinking of building it up as track bike, as it has horizontal drops. I guess it will be suitable for TT events- persuit, kilo etc. But is it at all possib...

Kieran

Thanks buddy, I never knew the photo's went over more than one page.

Kieran

For me this was a very interesting although ultimately unsucessful race. On lap 1, some guy broke off the front and got 200 metres. So I bridged over, and we quickly got a nice little gap. But quickly my helper died and left me stranded. Luckily two more bridged to me, but they refused to work, and ...

Kieran

I will probably enter for both days too.

Kieran

Okay James, this one looks good.

Kieran

I think overall we got pretty lucky. Simon you should have a big chance with such a generous grade. I think your bunch is the one to be in actually, perhaps I will sit in on my bunch and let you catch us, then we can pick it up a notch and keep the chasers away till the end. You should be right to o...

Kieran

I am more than happy to do this one again.

Kieran

Hey James, before you go ordering your new frame, I may have one for you at a pretty nice price. See below for the full bike. 850 grams for the frame! http://www.jamisbikes.com/usa/bikes/08_bikes/08xenithsl.html My frame came without groupset and controls, so I might get the full SL bike and then sc...

Kieran

What others have said is correct- the proper carbon pads stop nicer, and there is some risk of alloy getting in the pads. However, I have just been using plain shimano pads on a variety of Zipp carbon rims. The braking power is not great, but acceptable. In an emergency as in a race, just put the ot...

Kieran

I have banged on about this before, but the Conti Competitions are excellent tires. The newer ones with vectran liners last longer than the onld grey ones and are even better at puncture resistance. There is only one time I have gotten a flat on competition tyre that was not due to be thrown out, an...

Kieran

I would definately be up for this one.

Kieran

Here is the best graph I could find to explain: http://www.sheldonbrown.com/rinard/aero/grafik2.gif I know it plots power against velocity, but the relationship between power and force is linear so it shouldn't matter. What you will notice is that at 50k/h we're already off the top of the graph. Act...

Kieran

I didn't realise it was this weekend. I don't think I can do it actually. But have a great race.

Kieran

Don't worry too much, i'll still be doing plenty of racing this year. I've got 11 or 12 races in my plans for this year, with 5 more possible, so there'll be plenty for me. I'll even be at Heffron a bit. I know racing is the best way to get some form, i think it's a more consistent training pattern...

Kieran

Regarding wheels, you often see riders at club races with really illegal wheels like old spinergy 8 spokes, so if they can get away with that then a velocity rim will be way under the radar. This is a kind of obsolete rule from when the first deep carbon rims came out, some could shatter or buckle o...

Kieran

[quote="jimmy"]

However, I am aware that not everyone can climb like me

Is there anyone (in our club at least) who can climb like you ???

Kieran

Sorry but one KG over 1 meter is 9.8 NM Torque= Force*radius Force= Mass*Acceleration (of gravity in this case) Torque=Radius * Mass * Acceleration So in this example, mass is 1 kg, accelerationn is 9.8ms-1 (gravity) and radius is 1 m= 9.8NM Don;t get it wrong, or you will end up with almost ten tim...

Kieran

Yeah this is a really good race, I was at the last one and wanted to go this time, but had to work. When is the next one I will come for sure.

Kieran

Well this was a very enjoyable and well run local race. The scenery and route was nice and there was a good turnout. Me an Eugene both finished out of contention but near the front, about fifth or six. Eugene was in A, I was sandbagging in C grade. Thanks Eugene for promoting this. I will definately...

Kieran

Okay I am in for this, I will plan to meet you at the crnr of Killeaton St and Mona Vale St Ives rd at 7 am. If I am not there I have slept in or gotten a lift.

This should be fun, although my form is better than expected after the crash there is still much room for improvment.

Kieran

But here you talking about say 60 rpm vs 90 rpm. I don't think you need to do speed drills to learn to spin at 90rpm, you would be better off just riding hills at 90rpm over and over. Also, as 90 rpm is less efficient than 60 rpm in a metabolic sense, you will need a stronger cardiovascular system t...

Kieran

Are you going ????

Kieran

This is an interesting discussion which brings up alot of issues. In short, Simon is absolutely correct on the benefits of high speed leg work. The benefits are of a neurological basis- your neuromuscular system (muscles and the nerves that control them) are trained and adapt accordingly at specific...

Kieran

I can get one for $12.00

Shimano BB-UN26 68*110 mm

Kieran

As long as i don't have work, I am in.

Kieran

I would definately be in for this, but this depends on if I have some replacement forks by then!!!.

Kieran

The trick is, lean the rider, not the bike. That way the pedals don't get closer to the ground. After learning the hard way and getting launched skyward by dropping a pedal, I know know you can pedal the whole course at 40+ kph with the above trick.

Kieran

Kieran, sorry to hear of your accident. What's the situation with it's repair? Regarding the repairs to the rider, I am on the medicsre waiting list to get my collarbone pinned and plated, regarding the forks they will be upgraded to some jetstream forks. I have a new wheel in the process of being ...

Kieran

Actually it was a real old wheel, the stuff inside is plastic bagging to enable the pressure moulding process. It looks like quite a bit of energy was dissapated by the carbon, a bit like a crumple zone.

To insert the pic do I just put the exact pic url in the brackets???

Kieran

Okay see the link to check out the damage:

http://www.flickr.com/photos/21490004@N05/2085352865/

or maybey this works

Kieran

Thanks for starting the report James, ive really been in a bit of a daze, I took a bit of a hit on the head and haven't recovered fully yet. Also spent most of today working out how to get myself back together.

I have some good photo's but don't know how to insert them.

[/img]

Kieran

James- I had the same problem, "credit card error contact your bank".

Should be good fun, you and Eugene will have to give me a briefing on the race and some tactical suggestions, hopefully we will be in the same grade, I put you down as a reference for grading purposes.

Kieran

Ok, time booked of work and entry in, time to ride some more hills.

Could not find any other DHBC riders on the list yet, last chance today guys!

Kieran

My reccomendation see:

http://www.cellbikes.com.au/p_484_Ameri ... _Australia

I can get them for you for app $200 less.

Kieran

About $5000 inc GST

Kieran

The frame is nice, but also check out the components, I could sell the wheels, cranks and bars and pay for the whole thing.

Those FSA cranks are pretty rude!!

Sorry, there is no alloy version of this setup, but i will have a look around to see what i could get for you that is suitable.

Kieran

See http://www.cyclingnews.com/photos/2007/tech/shows/interbike07/index.php?id=/photos/2007/tech/shows/interbike07/interbike0712/Jamis_Xenith_T2 Pretty cuting edge, the plan is to sell/give away/save the TTbars and shifters and stick on some DA road shifters. I can get a really really good price fro...

Kieran

Sounds good, the more racing the better!!

Kieran

I was also looking at having a go, the good thing about the ITT is it gives you a perspective on your current level of fitness and training effectiveness.

Kieran

Well I was going to jump in earlier but decided to give James the chance to recover and kick off. Riding the TTT made me really happy to be a DHBC member, despite a lack of training and almost no experience, we managed to put in a team, fininsh the 80+++ ks and put in a respectable time. Ten points ...

Kieran

Yopu should check out the latest Bicysling Aus magazine, there is a reference to Clem Eagle, P45, Gary Sutton: "The first bike I had was a Clem Eagles. Clem was rick Eagles farther. Rick was a great champion and a real gentleman. He was one of my pinups because he was well mannered and showed r...

Kieran

Ok I can get out there any time, 9.00, 9.30 sounds good, I will probably get a lift out from my parents place, near Hornsby. Also, checking the rules you need to wear the registered team uniform, as i don't have a DHBC jersey, if someone could lend me one that would be great as otherwise I might not...

Kieran

Went out for another spin today, definately moving pretty well, but it is a bit of a steep learning curve learning to climb in such a forward position and with little leverage afforded by the aerobars. Even still, i could get much lower and be comfortable on the flats, but I never had any spacers to...

Kieran

If you ran tubs, you could get some Conti olympics and run them at 220 psi.

http://www.cellbikes.com.au/p_616_Conti ... r__Olympic

Kieran

The more I look at this bike the more I realise what a great find it is. Apart from the Gran Sport groupset, it appears to have the rare 40 hole Gran Sport hubs. These are also quite valuable as well as rare. It's hard to tell, but it also looks like the spoke lacing is 4-cross, which makes for a s...

Kieran

Well I finally got to get back on the bike and do some riding after weeks on the indoor trainer. Tried out the new aero bars with the seatpole in the forward position (the Cervelo seatposts are designed to be swapped). Ive never used the Cervelo frame set up us TT. The position I ended up with after...

Kieran

I just cant get the Deda GCB aero bars installed on my handlebars without the bars and rest pads slipping around the handlebars. I have tried putting rubber strips between the handlebars and the clamps to no avail. I don't know if I am doing something wrong. I think I hate the Deda GCBs. Try checki...

Kieran

If a right angle triangle is 533m along the bottom and 31m on the vertical, how long is the sloping side? Anyone young enough to remember maths? Well it is the square root of the sum of the squares of the short sides, so L= sqroot ( 533^2 +31^2) = 533.9 meters. Or actually 533.9007398 Or we can work...

Kieran

Sure, anyone can do it, you will just need to get my rego number off James as he still has my licence. Even if Simon is only a maybey we should put him on the list as we can always end up short but we may not be able to add extra people later.

Kieran

I think james is going to enter our team, but that is great news if you can ride it, as we were looking like being 1 short.

Either way good luck at Unaderra.

Kieran

Developement is a good measure to use as you can turn cadence straight into speed very accurately. This is how your speedo works. If you find the manual it usually has a circumfertence chart, note that even thicher tyres can make a significant difference. You can then get speed by Speed(kmph)= 3.6*C...

Kieran

I should be able to lend a hand (maybey just one) where needed.

It is really great to see the club running events like this.

Kieran

Sure, it is alittle excessive compared to $25.00 for the PLT

Kieran

Also i really want to do the tour of bight, so count me in.

Kieran

How about this one:

See http://www.rotorbike.com/2006/s1_main.htm

Kieran

Before you look at using a shorter stem to get a shorter cockpit length, try shoving the seat forward. You will then be able to get even lower comfortably and efficiently. For TT, the tip of the seat cannot be forward of the BB by UCI rules, but i doubt they will be checking.

Kieran

What makes me think that you can is the fact that alot of older riders have competed at the highest levels- Ekimov was into his 40's when he retired, and he wasn't riding in masters races. But as fas as cycling aus rules, i don't have a clue.

Kieran

Good point, this sunday we should hit some of our riders up to be in the team. Also, can masters riders can ride "up" a grade or two in elite, if so that broadens the scope, i tend to think they can. Maybey Eugene might like to have a go???

Kieran

Good news is the doc says i'me okay to ride, so all roads lead to calga!!!

Bad news is i still need to wear a splint for the next two weeks, but i am just happy to be able to ride the TTT

Kieran

No, i wasn't on the bike, it was a case of anger and frustration leading to stupid actions. Short version is my arm ended up going through a front windscreen. There are no broken bones but lots and lots of stiches and two partially severed tendons. But it looks like i will be out of the cast on thur...

Kieran

Guys Ime still really keen for this one but may have a little problem. I had an accident on saturday involving a car windscreen and damaged by hand pretty bad. I should be right but need to see the doctor on thursday. Can still ride the indoor trainer so staying in shape. Also i have 2 sets of alloy...

Kieran

Mike, you don't need to lower the bars, but the big point to aerobars is to help you get in a stable low position. In general you should be looking to drop at least an inch from a standard road setup. By running no spacers and a 8-10 degree stem in a downward position you should be about right. Fasw...

Kieran

No probs I can help you out there. I Will have a look for the syntace bars and get back to you. For a quick primer on setup, see http://www.cervelo.com/content.aspx?m=Engineering&i=TriBikeFit, I am happy to give you a hand, but you will need to do a few training rides to get comfortable with the...

Kieran

Okay looks like we have an elite men team coming together. Any more takers??? Regarding gear I can get most of the stuff available wholesale in aus, OVAL is not available but the other stuff should be okay to get. Pricey stuff may be cheaper to get through the foreign oem online shops though. Also I...

Kieran

Pretty sure it is 28 October

Kieran

Okay we probably should be making a decision on this one soon. On a slightly related issue, I just ordered a set of Pro carbon windjammer aerobars, I got them direct for $150.00. Should turn the bike into a good tt setup. Also got some 42 c-c bars, the 44 I am running are too wide. If anyone ever ne...

Kieran

Sorry mate tried to enter but didn't have my license number on me. Also found out i have work on so no luck for me anyway. Enjoy the racing!!!

Kieran

OK sounds good will try and enter ASAP>

It is very rare for the front ring to skip as the rings usually last a long time.

I am really interested in this one, i can probably help out with some TT gear either way. Any news onthe skinsuits???

Kieran

Hey all i just came back from holidays up in Coffs harbour and decided to take the bike. Must say the riding there is bloody amazing with massive mountains just inland from the beach. I didn't get to ride it but there is an amazing road inland to bellingen and dorrigo which takes you up to abave 100...

Kieran

Fantastic, well done. Would have loved to be there but I have been too sick to ride much lately.

Kieran

okay this one looks like fun, i'm in if we have some others, as usual i will need a lift of some sort as i can't drive.

Are you entered James ???

Kieran

A few points. My frame cost me $600. It is very aero. When you lower the bars you put more weight on your hands, put stress on your back and tend to cramp your legs and chest. You can get around the last problem by running a steeper seat tube as in TT frames, although there are UCI limits. This open...

Kieran

I could help out, I just may need transport to akuna bay. may be too young though (26)

Kieran

I would have a look at the pro windjammer, it has two seperate extensions so is quite adjustable and will fit the 31.8 mm bars.

I can get some at wholesale price but will need to know quite soon.

Also comes in a carbon version.
