Yah, but durability is of course relative. No problems with my wheels after a couple of years of intensive use. My Stans Olympic rims are still going strong after about 4. Best advice IMO is buy what makes you happy!

I have a set of DT RR1.1 rims, with a PowerTap wireless hub on the back and the matching Cycleops front hub. DT Comp spokes (I think). They weigh in at 1700g so minus the PT, you should get in under 1500g. They seem really solid and easy to self-maintain. For something a little different have a look at these: http://www.bikeradar.com/gear/category/components/wheel-sets/product/ardennes-wheelset-08-32321 23mm box rims, built to withstand the cobbles. Weigh 1400g

Thanks, was really just of academic rather than practcial interest! Given that (most) cyclists have an (in principle) infinite number of gearing options, there would seem to be even less relevance to the debate.

Ok, so contrary to what I thought, you would acually need a stronger set of muscles, but they could be less fit! Or am I completely off track now?

Would it be correct that in order to do the same work, in the same time, on a shorter crank, you would need a higher cadence?

TitusTi are you using the S-works SLK variety or the normal LK. How much do the non-tubeless weigh?

GoLefty, what is the weight difference between an XTR (new) dual control setup and a SRAM grip shift setup? Obviously it depends on the brakes you use for the SRAM setup, but is it significant?

Thanks for the advice!

Has anybody had any long term experience with these. They seem very popular in the pro ranks and are very lightweight, but are they reliable as ordinary trigger shifters or dual control?

I've only used the XT cranks (the older ones which I think is the M760) and they are brilliant. Have not had to replace the BB in over 4 years of riding.

Just started using Specialized Fast tracks. very impressed with their handling and they seem to be as good as any tyre in the rolling resistance department.

I would hate to know what his TSB is by now! What I find quite suprising is how low his heart rate is. Whilst I can't tell what his max is, it must be at least 190. His average for the 1 first hour is 156, which is supposedly his threshold. That seems way low. I suppose it could be explained by the consecutive days' racing.

Really amazing how low their HRs are.

Taking it further. How about an urban MTB night prologue. Loads of spots in CT where this could be quite fun.

So if his IF was less than 1 for a 36 min TT, he wactually being a bit of a slacker

Agree its a nice idea, but probably left for the prologue where you don't need such fancy lights and you don't have 1000+ riders in a bunch!

5.2 is my best. Normally about 5.1 w/kg

From what I've read it appears that power outputs are starting to drop, the implication being that the sport is becoming cleaner. If so, the riders could be riding more conseravtively, knowing that there is no loner a 'magic bullet' at the end of each day's racing!

Good point! David Millar averaged 400w for a 36 min TT by way of comparison (www.saris.com)

You do still need to buy the computer unit (Garmin 705 at R 6K seems best option) and possibly new cranks if yours are not compatible with the Quarq spider.

mini-hijack, but where can one get a decent but cheap air compressor that will do the job?
