oh andrew, come borrow my race wheels some time. you will not regret it.
You’ve lost me.
My new Zipps have ceramic bearings and roll noticably different to the last pair.
Surely once you get into ceramic bearings & titanium sprockets, you’re going to have a race bike AND a training/commuting/other bike with more durable components?
Read more carefully Matt, I’m talking about the vast majority here, and how it won’t affect Joe Club Racer’s results. How many seconds will ceramic bearings take off your ITT time? What is the quantifiable difference that having 11 sprockets compared to 8 will make in a 50km road race?
Feeling harsh and tight doesn’t necessarily translate into higher speeds / lower times. This has been proved many times before. 20mm tyres at 150psi might feel faster if you equate harshness with speed, but 25mm tyres at lower pressures will roll faster.
I don’t dispute the superiority of lighter wheels, tubs vs clinchers, stiffness where it matters, but it’s simply not going to provide a significant benefit for 99% of riders unless the placebo effect is particularly strong! Look at the words you used to describe your bike, all subjective about the way it ‘feels’, not ‘I changed my bearings and my 1km ITT time dropped by 3seconds.’
New posts edit:
BB: How about we time you doing flying 200s with steel and ceramic bearings in a blind test (noone knows except the wrench which are installed). I’ll bet you your times do not vary beyond experimental error/variation.
Matt: Apart from being new Zipps, what else changed, tyre, rim, spokes? Too many variables. Again, do a roll down test on a short hill multiple times with steel/ceramic installed and show me the time differences. Spinning the wheel in a truing stand doesn’t count.
i put campy pistas on my race bike and took 0.4 off my best 200 time
they are not ceramic bearing or anything
it was just a hot night
I was speaking to Paul Hillbrick about this, and he suggested keeping a logbook. Only change one thing at a time, note it in the logbook, measure improvement over a suitable period of time (usually weeks), and adjust where necessary.
Most advice I come across is pretty primitive in comparison, and instead tends to be relative to the bank balance of whoever’s giving the advice.
truest thing said yet.
I’d get a similar effect with Brenno’s race wheels.
Too many variables though (in order of decreasing effect):
Box section Fiamme -> Deep section Shamal
32 spoke -> 16 spoke
Old Clement tub -> Vittoria evo pista clincher
Brass nipples -> aero alloy nipples
80’s Record hubs -> New Miche
grease, cone adjustment & condition, shellac vs glue, temperature,
Steel bearings -> ceramic bearings
Eat ze wagon wheel.
Eaaaat ze wagon wheel.
this is by far the most hilarious quote i have ever seen on fixed dot org! bravo!

RE: the “noodle BB.” It’s your steel frame that’s flexing, not your solid alloy cranks
0.4 is a lot! (well done alex)
blakey, are you asking to borrow them saturday night? it’s going to be hot too… there could be some PBs toppling…

i really did make a fool of myself.
in re reading my previous comments i am sorry to admit that i looked (and still do) like a complete and utter turd.
sorry about that one.
No problem. Good recovery.
We should have a ‘post your roadie’ photo section.
I hope you’re not carrying panniers on your ride, your bike will snap like a twig
+1 make it so
No problem. I’ll get onto it later today when I’m back home.
I think it’ll be a good exercise in showing that the community on here is more diverse than people think. Fixed is only one part of my ‘cycling’ world.
Done
