comment Why use 54T (or bigger) chainring?
It's not obvious to me, so you're saying using bigger chainring allows selecting lower cogs -> closer ratios.

@Kibbee bigger chainring by itself makes gear ratios wider, not smaller. This is easy to check by watching speed difference between gears when in small and big chainring.

comment Why use 54T (or bigger) chainring?
I thought sprinters would need them more? If I watched tv correctly, the trains already running at 60+ kph in closing kms, they should already be at top gear. With sprint speed at finish line < 80 kph, they only need ~130 rpm. Right?

@Blam can anyone drive it that fast? 105 rpm cadence 50x11 already gives ~60 kph. How much faster do you want to get and why sprinters aren't having them?

comment How long do Garmin's cycling GPS devices take to get an initial GPS lock?
I also feel car GPSes lock faster and they don't have data connection. I don't think I wait for it to lock before driving. Any reason for that?

comment Aerodynamic effect of drafter to the draftee
I think drag caused by air behind really answers my question. It explains that in a group, the first and the last riders are doing some work.

comment Why to choose 36 or 32 spokes (or another number)?
Weight weenies is a small class. I think less spokes is more common with aero wheels; aerodynamics affect all riders. Unlike weight which only matters when accelerating or on steep gradient.

comment Advice needed re Carbon Fiber vs Shocks
I don't think you can find data for frames other than road bike frames because big companies sell road bikes. The point is those are all carbon fibre frames and the closest numbers if you want to compare against shocks. I also don't see price mentioned as being a factor; lot of people commute on road bikes too. I just remember, Trek also sold carbon road bike (Trek Pilot s.p.a) with rear "suspension" and normal chain stays. S.P.A = suspension performance advantage. I think the travel was also about 0.5 inch. It's got a mention on en.wikipedia.org/wiki/Bicycle_suspension.

revised Do road tubeless tyres lose air faster?
Made the title more explicit and readable. Add tag "inflation" and fixed some minor details in the post.
