You guys are amazing! Fantastic effort. With 5kg lost, you are seriously dehydrated. Even two 750ml would not have been adequate for the hydration needs of the race.

weiyun

Staminade contains Mg. Powder tubs are available through the supermarket.

Otherwise hydration as you said, and then there's sudden training overload, pre and post exercise stretching. If things still don't turn, then you should have your electrolyte checked out by your doctor.

weiyun

Ok guys! We are 6 days away and we should work out how we can meet up for a photo as a minimum.

Looking at the weather projection... I beg there not be another wet and windy one like last year.

weiyun

It's still 6:30am at Mick's unless you forgot to adjust your clock before going to bed.

weiyun

I get the feeling you've cheated a bit with this price, considering it's a $600-800 track bike you've put these parts on!

Simon, I think you'll get shot down on your statement. But I'll let Mike shoot you.

weiyun

its only 30 bux
is it worth it though?

I got my latest 750ml water bottle from a trade show stand, for free. You be the judge on value... $30 divided by $0 = infinity. So it's infinitely more expensive.

weiyun

Sounded like a stop screw setting issue.

weiyun

It was a stormy afternoon last year too...

weiyun

Nice! You win the economy award.

Now the question is, how are you going to ride track?

weiyun

See you on Sat... Weather permitting.

weiyun

I think you are one year ahead of yourself.

weiyun

High tech water bottles

There must be a gross oversupply of small B&W LCD screens out there...

weiyun

Clearly Geoff had too much to drink last night!

weiyun

Hey, we all know T-Bone is not a WW for nothing!

weiyun

OMG... Damian Da Man is back!

Hey, stop being a geek and caring father. We miss you on Sun rides!

weiyun

I'm not sure you spent enough money Huw, Going by the latest machines on fixed gear gallery!!! Disc wheels are in this season...

http://www.fixedgeargallery.com/2007/oc ... oolfie.htm

That's a track bike, not for road consumption.

weiyun

Wow, congrats to Michael and Frank... Upgrade time!

(one day i plan on venturing back to e grade there and finishing a race
though it may mean missing saturday slowies :S

That's a pathetic excuse Tim. Ride the slowie in the morning and then race in the afternoon. No conflict!

weiyun

Thanks for the explanation Lindsay. So I gathered from Huw's experience that it is possible to change the drop-out in a steel frame. I guess the reverse question now is, if the parallel drop-out is so great, why aren't they used for regular road bike? Was it because of the presence of RD? The point ...

weiyun

He had a lot of big drill bits!

weiyun

Do you think there'd be much flex in that chainwheel?

weiyun

How important is it for a fixie frame to have those track horizontal drop-outs?

weiyun

Yes, the dark metal finish is quite nice and you might have seen them on my Ridley.

weiyun

Nice narrative Huw!

What will you do with the Fulcheni frame now? Put it up on eBay so that another poor soul can enjoy the resurrection process?

weiyun

Yes, Centennial Park is just down Oxford St. A Right hand turn down Flinders St and down Anzac Pde is the smarter route.

weiyun

1) Helmet is compulsory here in Australia. So yes, bring your helmet. 2) Radisson is very close to Centennial Park. As a matter of fact, I ride past it when I ride over to Centennial on Sat morning. You just have to turn 2 traffic light turns to get there. If I am riding on that morning, likely, I'd...

weiyun

It was a hot day today on the Spring Cycles. Met up with Eugene and Ron at Olympic Park and stayed with Eugene to watch a Div 2 criterium race they staged. Short course criterium and it was very spectator friendly. Eugene threw in $50 on behalf of DHBC to make them suffer more.

weiyun

All the information on the annual Gong ride and our team are on the link below. You are welcome to join us. Weather permitting, some of us will ride back to Sydney. Otherwise the easiest is to catch an event specific train back.

http://register.gongride.org.au/?Dulwic ... cycle+Club

weiyun

Sorry, Spring Cycles...

weiyun

That's a good Photoshop job! Very nice!

weiyun

They have you covered at every price point. Then x2.

weiyun

Actually the price of the Vitoria's has come down and is around the same price

Sorry I didn't make it clear earlier. I was referring to the GP4000S being more expensive than the GP4000 with chili.

weiyun

Nice granulation forming. Maybe we can restart the shave vs no shave discussion again.

weiyun

But the side wall of GP4000 would easily last more than 2 years if it doesn't get scuffed, as on the track. Plain riding won't damage the side wall.

The higher TPI supposedly provide better handling. IIRC, GP4000S has a similar count as Vittoria's Open Corsa Cx. Obviously it's more expensive too.

weiyun

But you are less likely to get sidewall damage on the track than on the road. So wouldn't it make more sense to put the GP4000 on the track bike? Otherwise bear in mind there's Conti GP4000 and GP4000S. Both of them have the new chili compound if so labeled. The S model is their race specific model ...

weiyun

I don't have a fixie so I don't think I can make it.

Then come down to the Gong with us, and potentially ride back...

weiyun

Here's another way to circulate the velodrome
http://www.youtube.com/watch?v=tmBKe7ra5fw

Would the skater get smashed into the ground if he gets into an aero tuck?

weiyun

What's Tim up to these days? Haven't seen him on our Sun ride for a long time.

weiyun

Why not? But don't worry about the start time, we are going to leave with the first wave at 6:15. So show up early is the word.

I understand our Capt has bailed due to other commitments and Sue will be starting from the 1/2 way mark.

weiyun

Risk management is a necessary part of the fun.

And what the heck was that cyclist doing out on the highway at 4:30am?

weiyun

man unless you are on a fixie it seems like better training to do a fastish lap between each hill climb. Matt has also started doing it backwards, which seems more useful for road riders I think that you'll have to consider that the term "better" will have to depend on your training objec...

weiyun

Thanks Fixedgear. That gave me a good reference of the gearing range provided. It's amazing how much the drive train has evolved since those days.

weiyun

Well, there is a slight drop in grade after the initial kick. I am starting to appreciate how significant a one percent grade change is.

weiyun

Shops and cafes at Austinmer do a good job. Watch out for the greasy kebab-shop floor in your bike shoes - the cleats slide like glass!

That's why I wear MTB shoes.

weiyun

Wonder if you can get knicks with hip protection?

Yes you can. There's a model of knick that has side panel reinforcement using kevlar fabric or similar. It was advertised and sold on one of the US web sites. Just prior to that, I thought I had a brilliant patentable idea.

weiyun

When you are dying, fat or sugar would no longer be a concern.

weiyun

Thanks. I'll remember that suggestion... Whatever Dolphin Combo is.

weiyun

There's a shop at Waterfall?

weiyun

Chainring combinations such as 50/46 or 51/47 with a widely spaced 4 or 5 speed rear block were common until the mid/late 1960's, in part due to the limited capacity of many of the contemporary front derailleurs. Note on this bike, the front deraillueur cage only slides sideways on a pushhrod, and ...

weiyun

The miracle of skin, it's renewable... Until you are old and decrepit. Same can't be said of those knicks.

weiyun

You'll never see those shorts again

Aren't you glad that you posed with it one last time?

weiyun

Lovely find! What's the story with the chainrings? Two of them aren't very different in terms of the number of teeth.

weiyun

Where are the fuel stops on the way back? Particularly water.

weiyun

Seeing what other clubs have done using the park loop, here's something potentially interesting for us to do. How about a time trial up that Centennial Park hill?

weiyun

I don't think I have the condition nor petrol either but would be a good challenge for what's it worth. Planning to slow coach back if the weather condition is reasonable and take the easiest route. We can make the final decision after we get there.

weiyun

That critical 1m... You may just bonk in that 1m if you don't do your calculation right.

weiyun

So what was the story? The guy who came third had a grudge against the guy who came second?

weiyun

Yes, got the message. Fouad + 1 and me so far.

weiyun

Confirmed 6am meet at Mick's.

weiyun

Nothing special really. Sports scientists use GPS data all the time. It's even more amazing when you can combine a rider's power output characteristics and various other variables with this data. What it means is that they can fully predict the outcome of a race, or try different hypothetical race s...

weiyun

Nope, no short cuts. Unfortunately with the tree covering, the GPSr sometimes loses the signal, rendering what appeared to be a shortcut. It's much better seen on the plan view. Also, we exited through Paddington gates after a final tackle of the hill. The extension associated with that last peak in...

weiyun

The hill in Centennial Park seemed to have become the focus of our Sat Slowies group with quite a few dedicated riders who just want to ride up and down it for the duration of the ride... What are you guys thinking?!? Anyway, just so that you guys can explain your bizarre activity on beautiful Sat m...

weiyun

Excellent morning today and the next stage of Le Tour continues... I found my kind whilst there... http://i167.photobucket.com/albums/u149/ciprol/WeiyunMambo.jpg Not exactly sure what Mike was thinking though. http://i167.photobucket.com/albums/u149/ciprol/MikeSuperman.jpg And this next one was just...

weiyun

GP4000S still has higher thread count, whatever that's worth.

weiyun

No confirmation on the routing. May just do the regular RNP loop also. We can get a consensus on the ride.

weiyun

Jobst Brandt is a dangerous man to pick on in a technical flame war. And he is still very active these days.

weiyun

Cool. I might do one of two things. start with you at Mick's, or latch on at Sutherland at the Audley entrance to the RNP. Is that fine by you? For safety reasons, I would prefer not to ride solo if it can be avoided. Yet again, it doesn't make sense for you to ride 30mins to get to Mick's. So let'...

weiyun

I was told you climbed like a goat last Sunday. You have nothing to worry about. In any case, if you are keen on some weekend climbing, I'll be happy to join you. Will never pass up an opportunity to go through the park. In at Audley and out at Helensburgh is fine by me. Let me know the start time....

weiyun

Look to be new kid on the block and the review wasn't exactly flattering. A few question,

- Why are you thinking of using it on the track? It looked to be a road tyre.

- What are the performance priorities of a good track tyre?

weiyun

The key is to have the tools to destructively take it off, right? Ashfield Cycles? Bob at Stanmore? Shouldn't be rocket science.

weiyun

The 200km return ride down to the Gong in 4 weeks time is starting to worry me. So anyone keen to ride the RNP this Sun, 14 Oct? Might even be willing to try out the loop down to Helensburg.

weiyun

I usually ignore the cameras when i'm stuffed, because i just don't care anymore. I could have just been trying to get a tiny bit more speed into the bike, just hoping it would all be over quicker.

Admit it, it's your paparazzi reflex!

weiyun

My photo doesn't show what was going on up Gibralter, must have got me in a good patch, not that i remember having any.

You saw the camera in the distance and you stood up... That's your reflex isn't it?

weiyun

Here's a follow up to this gearing discussion. I contacted AIS and asked them what they use and in response, they sent me the Excel spreadsheet they use, which is a rollout/development calculator in metric units. I note also that it has two tables, one for 630mm diameter wheel and the other 672mm. I...

weiyun

How about just upload the PDF here? I'll leave one at our LBS.

What's the response so far numbers wise?

weiyun

lol man you lads are funy with all the fancy stuff you get up to
mean while theres me who changed gears once on saturday slowies on the weekend, not bothering to do the same on sunday to waterfall, because i didnt see the need to

It's called planning.

weiyun

Just did a careful check of the route profile from my last year's GPS track log. The reverse side of those hills after RNP are all around 10% grade of significant length. This is going to be a seriously tough ride back. And people are right, the ride out of RNP averages out to 5-6%, not as tough

weiyun

Thanks James for your insider's tip. They will be very useful info. From my point of view, the easiest route is the best route ie. Helensburg. Adding up the ride to home, it'll be 200km round trip... Ouch!

weiyun

Good. That means we'll have 4 riders on the early start (Faroud, MichaelM, JamesF, myself). Not sure when the ladies of the team would show up. Will ask them on Sat.

weiyun

I'd imagine it would be similar, early-mid afternoon?

weiyun

Word of Tempetation appears to have got around. Correctly or not, I told him that it would probably run next year, as part of the celebration of DHBC centenary. He reckoned that with enough lead time next year, there'd be people coming from across Australia to do it. It is a novelty and I have seen...

weiyun

Seriously Weiyun, your better off being towards the front of the inital group. It will be broken up by the traffic lights and if your at the back, you will end up having to ride by yourself after leaving the slower riders behind. Thanks Mike for the advice. I do intend to start at 6am this year. La...

weiyun

I don't think that crank length changes the gearing or cadence or anything it just uncramps your legs a bit for the tall guy. The longer the cranks the closer it is to walking.... I actually prefer 170mm cranks over 175mm cranks because i'm used to them. I can spin a much higher cadence...But I hea...

Don't you guys sleep;
Simon 2:56am
Weiyun 5:39am

Working...

weiyun

Just dawned on me. We can ride back from the Gong and be just in time to get a feed at Tempe velodrome. Maybe we can even sneak in for a ride on the track before the fixie folks arrive.

weiyun

Another issue apart from wheel size when comparing gearing on different bikes is crank length. I tend to think that Sheldon Brown might have it right with his "Gain Ratio" method. I recently changed from 170 to 175 cranks on the fixie and it made a noticable difference. Very interesting. ...

weiyun

So maybe the best way to go is with the majority and talk chainring/cog rather than in inches.... The problem with just the cogs is that it goes back to the days before gear inch calculation, in that you can't easily compare the various combinations. Along the same line, it doesn't give a clear pic...

weiyun

I'll talk to Grant next time and see how I can help. The jersey is our billboard and new members will come. Nicer the jersey, the better the exposure. Thanks for the offer of loan jersey but will see what happens come ride time. I'll need a S size though... A flapping jersey would probably be counte...

weiyun

However if you arrive at 6:15am then you will be at the back of a large group leaving at that time and for the first few K, you are limited to one lane, so overtaking is rather difficult. Better to be there early and get to start at the front. Hehe, given the standard of those in the early group, I...

weiyun

Thanks Geoff for filling in. It's always good to spread the words and communicate these difficulties, a helper might just show up.

I'd happy to assist with managing the jerseys.

weiyun

Forget about their start time. I'd say just show up early (6am). The later we leave, the more likely we'll get hit by the southerly.

weiyun

The MS Gong ride this year will be on Sun 4th of Nov with an unfortunate clash to the Fixie Century. Right now, we have a registered DHBC team in place with 6 riders on the roster. So whoever isn't in the fixie brigade should seriously consider riding the Gong, it'll only be just over half the dista...

weiyun

Yes, I can see what you are saying too. Given the differential b/n 27" and 700c is just under 3%, it's just convenient to not bother with relearning the gear inch chart. Further, given the numbers are typically not compared with other styles of bikes or used with riders' power data, there's no ...

weiyun

It's been brought to my attention that the route includes razorback mountain, perhaps 48-17 may be too high, even for a Mike the masher

Repeat after me... You are not a masher.

weiyun

see this issue is problematic because even though our gearing is wrong,it is what everybody in Sydney uses. So if you rock up to the track stating 700cc gears no one will understand what your on about. So it may be wrong but it's universal & it's trackie language... Gear inches is defined mathe...

weiyun

Nice one weiyun, that makes a lot of sense.

But you were right too, just the reverse.

weiyun

Hey Mike your gearing is 2 inches off. here's the chart..
http://dhbc.org.au/index.php?pr=track5

Guess this chart should be updated for current 700c wheels, or at least an explanation made that this table is based on old styled 27" wheelset standard.

weiyun

Yeh for some reason sheldon is off. I don't know why but if you ask anyone at the track what 48/14 is they will tell you 92 inch. & same with the charts Terry gives out at Rocky point rd & Al as well. I'm no mathematician so I can't tell you why sheldon is different but he is, Lindsay has h...

weiyun

Its because sheldon brown's calculator defaults to a 27 inch wheel

If you select 700x23, it'll still give you 90 inches for 48/14.

weiyun

Potentially available to assist.

Simon, more information on the exact time required. 5pm start but when do the helpers need to be there and until what time? Most of the positions appeared to require some experience.

weiyun

"You boys are soft nowadays, way back in 2007 my first ever fixie ride was 160k, now where did I put my walking frame"

How many inches is that walking frame?
