Designing a bike solely for climbing... - Page 3

I would love to try a pair of Hyperons. Man... those climbing wheels are the Victoria Secret of cyclingdom.
Sure, gearing.. and something steep as seat angle. Other than that, lighten up the bike and watch Pantani videos.
Having said all that i don´t like climbing.

Unfortunately, there are not many options out there for a "climbers" crankset, but the VBC does the trick.

I want a campagnolo triple crankset and a 13/26 cassette if i am on big mountains. Call me old. I don´t care.

Those are excellent climbing wheels. The Lightweight gipfelsurm are in the same class. However, I would recommend tubulars for both wheels.

No point in re-inventing the wheel. Existing gearing is perfectly adequate for the bay area, or anywhere else actually.

Lionel don’t you have hyperons on your climbing crumpton bike?

gravity is my friend... I coast by others that are still spinning.

Of course.

Indeed! What a wonderful set of wheels. I had a set of Gen one's on my Ti Davidson with Record 10. I could climb all day on that bike. Granted, I was 18 years younger then.

Nobody has brought up biomechanics or how the system changes as the grade increases... I noticed something in the data with my clients who use the Kickr Climb, when the front fork is elevated their torque drops off. That's because their body weight is no longer over the pedals. With steeper grades the rider position must also adapt.

As for gearing, to keep the largest muscle engaged you need to stay within a very narrow cadence range. The big jumps in an 11-34 are way too large. You would be better off running a mountain bike small cog like a 20T and running something much tighter in back.

But what do I know about climbing?

For the sake of discussion... if I want to design a bike for a 10 mile 8% grade hill race. What would you suggest? And yes I agree you know a thing or two about climbing.

Fact> a triple crankset is the best solution in this case.

Fiction> you can drill holes on everything to "make the bike lighter". Remember those times?

they are still happening. Fast forward to 0:30 seconds.
