I'm in talks with form cycles to do a custom ti singlespeed for me.I dont know if I want 29 or 26.I dont know how the two different on long rides? Any suggestions on setup etc..
thinking of singlspeed but why 29r

I'm sorry, I have to disagree...I had a 16.5 lb Bianchi SS with a light wheel set (Stans hoops) and my current bike, a 19 lb Specialized Stumpjumper. The Stumpy climbs better and has a smoother ride over the rough stuff. Both are rigid. The 29er tires provide a larger tire contact patch, which equals smoother ride, more traction and better control! :thumbsup:cakake said:

I didn't cut and paste my quote very well. I agree that 29ers are smoother, and roll over terrain better than 26" wheels. That's why my SS is a 29er.
But I find the argument about momentum/inertia of the wheels interesting. Yes, they do carry momentum better, but only because they're heavier. You could get the same momentum/inertia affect with 26" wheels by making them heavier. Anyway, the "advantage" of extra momentum/intertia of 29" wheels is really an argument for heavy wheels (which I find amusing).
Of course, maybe I'm completely wrong, but I've not heard a better explanation.

No. The further from the center, or hub, you get, the more rotational mass. 26 vs 29, the mass is ALWAYS going to be distributed further from the center on the 29" wheel, thus providing more rotational mass, making it harder to spin up than a similarly weighted 26" wheel, but likewise providing more inertia with which to maintain the momentum. Simply making a 26" wheel and a 29" wheel weigh the same will not make them even.cakake said:I didn't cut and paste my quote very well.

Agreed. It's a function of weight and distance from the center, as you say. I didn't claim equal weight wheels would have the same rotational mass, just that if you added enough weight to a 26" wheel, you could make it have the same rotational mass as a 29" wheel.nachomc said:
People often pay a *lot* for wheels with low weight, and hence low rotational mass. I just find it amusing that one argument *for* a 29er is that the wheels have higher rotational mass, and yet people making that same argument go out and spend big money on lighter wheels.
