27.5 (650b) versus 29
« on: May 02, 2014, 10:14:54 AM »
I'll be purchasing a new XC hardtail in the next couple of days, and I'm kind of on the fence about whether to go with 27.5 (650b) or 29 wheels. I'll be using the bike primarily for XC racing (DINO series), but I also want to use it for endurance racing (50+ miles). I'm 5' 8", 148 lbs, with a 32" inseam. I'm upgrading from an old Trek hardtail with 26" wheels, so both 27.5 and 29 will be a marked improvement. I've been leaning towards 29 because of the endurance aspect, but it would be great to get some advice from others!

honestly, the best thing you can do is ride each.  only you can decide what works best for you.

Glad to share my experience and opinion for whatever it's worth.   My opinion is that a 29er is the best wheel size for XC riding although shorter riders might be better off with 27.5 or even 26 (if you can find one).I went from a 26er FS to a HT 29er two seasons ago.  I noticed a huge improvement in speed and felt like I gave up nothing in terms of handling or acceleration. My focus is on 1.5hr XC races.  The laws of physics favor a 29er from the standpoint of reduced rolling resistance (10% less than a 26er, X% less than a 27.5er) and better bump compliance than either (big wheels roll over bumps easier than smaller wheels).  IMO, the only benefit of a 27.5 is that it makes an easier fit for shorter riders, and for FS/downhill rigs allows a bit more suspension travel.

Bike wheel size is trail specific.  Lots of climbing go 26er.  fast long straights like racing 29er...

Gee, you don't say? :)  They kind of pigeon holed themselves into one market, being that of a dirt roadie. :)

Trek is doing some 650b's. There are a couple of them sitting in the Bicycle Station

Thanks for the comments everyone.  From other forums, and some dealers, it sounds like I could probably ride 27.5 or 29 without issue, so the choice really is subjective.  I'll be demoing a mix of 27.5 and 29ers tomorrow in Michigan, so hopefully something sticks out.

You are the only one who can decide that. People can tell you advantages of 27.5 over 29 and vice verse. You riding both bikes is the only accurate way to tell if you will ride one or the other

I agree with those telling you to ride each and see what you like best.
I am 5'7" and felt fine on 29" bikes from the past couple of years, the older ones I didn't like as much.
With Trek and Giant I like the 29" hard tails better than the 27.5" ones. With the exception of the 29" Trek Superfly FS, I liked the 27.5" bikes more when it came to full suspension from various brands over the 29ers.
Anymore it would be hard to go wrong with either size if you like the way it rides.
