If you can climb even a 10k 10% hill at 10 km/hr, you're a much stronger rider than me. In other words, you should expect to be exhausted by trying what you suggest.bianchi77 said:

(There are various formulas that show what your vertical climbing rate should be (on steep hills) for a given aerobic capacity. Maybe you can find them.)

Those are pretty high sustained watts. I think that kind of effort makes the best of riders hurt.

+1. That climb would have me puking a lung by 3k's.sometimerider said:If you can climb even a 10k 10% hill at 10 km/hr, you're a much stronger rider than me. In other words, you should expect to be exhausted by trying what you suggest.

Or what kind of tool that I can use ? How much ?

This "Dr. Lim" formula seems to work pretty well:bianchi77 said:Where can I find the formula ?

bike + rider weight (in kg) x 9.8 x elevation gain (in meters)

time (in seconds) = power (in watts).

add 10% for rolling- and air resistance to fine-tune the watt number.

While it is probable there are places where the road will pitch up to 10 or 12 % over its length, it is not likely to maintain that for more than a few yards at a time.

Lower gearing might help.

Maybe 39-25 or 27?

Here is a link to a calculator for you:bianchi77 said:Where can I find the formula ?

There is the Mont du Chat starting from Le Bourget du Lac (near Aix-les-Bains), France 13.5km for 1264m, for 9.4% average. There has been a race there in early July for the last 7 years, course record 48:30. The race is open to all, no license required. Most of the profile is given here: http://www.climbbybike.com/climb.asp?Col=Le-Mont-du-Chat&qryMountainID=6925 I don't think it's ever been used in the Tour de France, I don't know about other professional races.toomanybikes said:

More like 34x27 which is about 70 rpm for 11kph.cpark said:+1.

Not true. Many people can do much harder, it's just that cadence suffers. I've done 16% grade (spikes to 24%) for ~2mi on 39x25. A 39x23 is only a difference of 2rpm. 36 vs 34rpm.barry1021 said:

It sucks a lot, but it's not impossible. A friend did it in his 42x25. 12% actually doesn't sound that bad after that.

Gino Bartali won the 1938 Tour de France riding up the Tourmalet (a dirt road at the time) in a 46x19 (approximately 39x17). Those were the days....iliveonnitro said:Not true.

Lightweight, huh? Ok, per the bikecalculator site, for you to do 12 km/hr up a 15 km 15% grade would require 380 watts for 73 minutes. World class.bianchi77 said:I'm 61 kg my bike is around 7-8 kg..

To do 10 km/hr on a 10 km 10% grade requires 212 watts for an hour. Doesn't sound like much, but I couldn't do it. (I would require 270 watts, since I weigh more.)

Come and visit the Alps buddy. France, Switzerland, Italy and Austria all have a few mountain passes that would easily fit this criteria. Try THIS RIDE in Italian-speaking Switzerland...averages 9.7% over 15km.toomanybikes said:
