19 for a 10 is QUICK!!

That wasn't a 'test', it's how he rides all the time, having established through testing that it's what works best for him. Does it on 165mm cranks, too, which again is unusual, as slow revving testers usually favour long cranks. Look at the times; it seems to be working.

What's a more normal RPM? or what's the other end of the spectrum?

Also, don't environmental conditions really skew times?

Forgive the bone questions, just interested.

something like 90RPM would be consistent of 'normal'.

Oh, I was always told that 100-120 was a good cadence to hold. Tried a power test at 60rpm and I was struggling to hold it that slow. All the rugby players were complaining that they couldn't hold 60.

Also, don't environmental conditions really skew times?

To some extent, but those times are all set on out-and-back courses, so not significantly wind assisted.

Oh, I was always told that 100-120 was a good cadence to hold.

It's good if you can hold it, but hardly anybody is at their fastest in endurance events at such a high cadence. With only minor exceptions, the hour record was set with a cadence of 100rpm for most of its history. Maximum power is usually at high cadence, hence track sprinters putting out 2kW at 150rpm, but maximum efficiency is at much lower cadence, some lab tests suggesting about 60rpm. Time trialling is about striking the right balance between the two, to sustain the highest possible power without exhausting the fuel supply.

that's really interesting, I tend to run a much higher gear and spin less as it felt better but was worried I would have to learn to spin more - maybe I'll just up my gearing even and try that for tt's next season- thanks!

^ Looks nice, but is that just one of these for "grown ups"?

only for PRO..:D

Show some respect, cause you are talking about the Original Bicycle, the Genesis where it all started...

1st gen Aerospokes and cut down bars for swift city riding in dense traffic.

and early TT pad for your arm to rest on.

That bike have everything.

^ its got training wheels even though your feet touch the ground!

and several bottle openers.

good for doing barrspinz

Mmmm... Phil Wood & Indy Fab

i'll do it before someone else does
from current projects

pure class

great photos! very elegant.

Risers put on wrong, but somehow it's not too obvious... Nice

I've always thought that was a much more rational orientation for "risers"

He's allowed to get away with risers because of the lugs
in fact the lugs would allow him to get away with a pair of 'spoks on that

lugs are overrated

Photos with a small depth of field are overrated

Didn't that already get posted in anti-porn (where it belongs) months ago?

IF is hottt, except for hubs and chainwheel

possibly the nicest road frame i've seen - shame it's about 10cm too small for me

more pointy seat tube stuff. nice.
