I'd be curious to know what the quoted lead time is on UKSI equipment. Not a fluff "well, these things can take a few months or more depending on National Team demands" type of answer. I think that competition equipment should have a stipulation on maximum lead time, just the same way they have a maximum prototype window for products.

Asked my friend about the seats and seat posts over post race refreshments last night.

They were someone's honours project a little before the Olympics, all the saddles are exactly the same for each rider which was justified as they're only on them for 4 minutes or less. So far only one has failed in any way, not sure under who. Printed shell onto billet post/topper block item. Effectively a metal pivotal with some fore aft adjustment but very solidly attached. Small gripper on the front of the saddle is pretty much where the rider sits.

Seatpost is for aero properties, to try and help smooth the turbulent air from the opposite leg at extension, the vanes are slightly angled and apparently not symmetic. Some rider may not use them due to how their knees track during the stroke, knees in changes the desired flow patterns.

All very interesting and I'd like to give one a look over if the opportunity presented itself

You might be only on them for 4 mins or less *in races*, but you still gotta train on something day-in, day out, plus warm-up, etc. I can't imagine that's fun.

Interesting story. Thanks for sharing!

Plenty still use normal posts, rails and saddles for training and lesser competitions, see glaetzer on a prologo as usual. I think the fancy ones only get rolled out for serious tournaments where they want to take care of the negligible risk of a saddle moving.

A few of the pursuit guys come out to our local races so I'll see if I can get an opinion on what they're like first hand

I need a better front wheel track skewer than the Zipp one that seems to stiffen up and become impossible to tighten/loosen after a few uses.

Suggestions?

FFWD do one that seems to be pretty widely available

queerpunk 11-17-17 08:08 AM

anything with steel bits oughta do fine. strange about your zipp.

this would work.

southernfox 11-17-17 08:14 AM

tytyty :)

The problem is with the nut. Zipp simply taps an aluminum block to make threads. It can easily be stripped out. I think they chose aluminum to be lighter. A teammate of mine stripped hers out at collegiate nationals 10 mins before her race. Easy to do.

Maybe go to a LBS or Performance Bike and get a budget skewer. You can probably get it for free from a LBS by asking . Those have steel inserts for the threaded area. You may even have one at home. You know the kind of skewer that comes with a home trainer? You just need the nut off of it.

southernfox 11-17-17 05:48 PM

Yeah, when I got it off it seems stripped halfway down the threads. Dammit Zipp!

I have the opportunity to work with a cycling kit company (who sponsors me), who is willing to develop a high end speedsuit, pretty much based on my needs for track.

What are your favourite speedsuits? What are your must-have features for going fast AF?

(I have thoughts of my own, but I'd like y'all's too)

queerpunk 11-18-17 09:58 AM

this could probs be a whole thread on its own.

my answer is, first, it depends. if "for track needs" you mean "i'm gonna pull this on and off a few times a week all season long and want it to last for two seasons," then that's a very different track need than, for example, "an extremely aero but possibly fragile skinsuit that i'm saving for my target events and will probably be destroyed by repeated number-pinning."

but in general i'm interested in:
long sleeves
compressive fabric down below to keep everything in place
softer, breathable fabric above for comfort, especially through a hot summer season
long leg grippers
no dang collar
designed/cut for arms to reach forward (instead of designed/cut for arms to hang down at the sides)
no dang wrinkles
good quality chamois

advanced: clear number pocket?

southernfox 11-18-17 10:22 AM

Happy to make a new thread. Maybe I'll do that?

I haven't heard anything about Serenity bikes in a while. Are they out of business? Just curious.

That is what I have heard.

carleton 12-08-17 11:00 AM

Their FB hasn't been updated since 2015. The website is simply 1 image. It's safe to say that they are not in business right now.

I never saw any bikes after their initial first generation.

People local to Hellyer: I will be in town next week and would like to get on the track. The site looks like it has sort of dated info but does have an up to date calendar. If I wanted to ride in the evening some day do I still reach out to the scheduling email or just show up and ride? (since there is nothing on the calendar). Some velodromes are open park use when no schedule is in place, others are locked up.

Baby Puke 12-15-17 04:32 PM

Hellyer will be locked up if nothing with a supervisor is scheduled. You should email the people.

Winter is a slow time at Hellyer! There is "usually" no evening riding during the week in the winter. In fact, most of the sessions we have during weekdays are off the calendar right now. Those are all morning sessions when they do happen. Sometimes, if a supervisor is available, there will be a Tuesday session, but this time of year that gets announced the night before via email. Weekends are your best bet. There are Beginner Sessions at 0830 followed by an Intermediate Session at 10:30 on Saturdays. There is an "Advanced Session" on Sundays, usually at 1000. Those sessions are '"reliably" on the calendar.

Track floor pumps!
What does everyone recommend for a track floor pump. My current pump head is struggle to hold 180+psi for my race tubulars. Willing to spend the right money on a decent and reliable pump.


I have been looking at the Silca range of pumps; Pista and Super Pista pumps

I once watched a guy using a Topeak Joeblow Ace pump his disc up to 220PSI with one hand pumping while the other held the pump head on. I went out and purchased one right away. 3 Seasons on and still cranking out the pressure. Turns out the first high volume stage is also excellent for pumping up my MTB tyres too :thumb:

So he is Keirin racer in Korea so he speaks in Korean, but my question is do you think this is save way of glueing tubular tire?
He only put one heavy coat of glue and wait 24 hours.
He uses this method to glue his race wheel and other.
What do you think about this?

His step.
1) remove old tire
2) stretch tire
3) put tire
4) put really heavy coat of glue without removing the tire
5) pump the tire
6) clean excess glue with finger
7) look for gaps and add glue
8) wait a day

Morelock 12-19-17 05:06 AM

I don't have experience with this method, but I've glued a good number of tubulars, here's what I think. (take for granted there is some speculation)

In theory, if you were methodical in doing it and you used good glue, you'd probably be alright riding a tyre glued like this on "normal" roads or on a keirin track. (pretty shallow banks) In my mind, I'm gluing my tyres with the "worst case" scenario in mind, not "normal conditions."

I wouldn't want to glue my cyclocross tyres like that. (or my track tyres that I expected to bomb sharply off the top of the boards on)

*I do think most people (myself included) use much more glue than is necessary (I glue my own 2 coats on the tyre, 2 on the rim with a days drying between each coat, then a final wet layer on the rim, mount, although I've done 1/2 coats within a day when in a hurry for a race before with no ill effect. *for a road tt)
