Hey just curious to hear anyone's thoughts on sizing. I'm 5'9" with 30" inseam. I am between the 16" and 18" size according to the site.

I normally ride Medium/17" bikes (specialized) and am pretty comfortable on my 18" Fatty (on-one) However, the ETT and standover of the 16" 456 carbon evo seem better to me than the specs of the 18" version. (standover on the 18 is scary for my friends below)

Just curious on others' thoughts about which way they'd go?

"Looks nice, I wish I could swap out my original 456C for the Evo for the new geo. Do you think that the new frame will clear 650b wheels/tires like the old 456c?"

+1. I am interested in knowing this also.

Without having a 650b wheel on hand to test accurately, I took some pics with a spare 26" mounted.... hopefully this helps you judge the clearance. I'm just guessing, but it looks like both chain & seatstays will accommodate the added height of 650b, but you will possibly need to consider the width of the tire you're mounting. What you see are Kenda Nevegal in 2.35". Also bear in mind, there are a set of sliding dropouts available for this frame, so you could possibly go that route to do 650b is clearance does pose an issue.

Bad Andy - Thanks for the pics. In my opinion it looks like the 650b wheels will clear, but it may be limited to a 2.25 size tire. When you get a chance could you measure the BB height with your setup (looks like 26"x2.35" tires and a 140mm Fox fork)? I'm curious how much lower the BB is than the old 456c.

It's pretty much built at this point, barring tweaks to do after the shakedown ride. Using spare wheels until it's proper ones show up. Had to trim the rear brake line so I took the opportunity to learn how to do that and bleed the brakes as well. Nice. It's amazing how cleaning up some wonky cables up front can really tie the bike together ;)

Glad I went with the 16". Seems to fit great, I'll post up pics later and take the BB measurement as well.

Here's a pic of the BB height. Looks to be just about 13" even.

update: so far so good. I like it. Coming off the fatty for the last 6 months - the most adjustment was required to adapt to riding a sus fork again. The bike rides great and I'm happy I went with the 16" size, considering I was borderline. It must be big for a 16, so it works great for me. I usually ride medium's/17" in other brands (specialized) and my fatty is an 18". So take that for what it's worth I guess. Enjoying the bike, it feels like a razor in corners - nice and stiff and reactive. I haven't been jostled around in the bumps badly either so maybe the carbon is doing it's dampening thing? I recall some reports from original carbon 456 owners saying that it was harsh but I can't say I've experienced any unexpected harshness with this bike. YMMV but it feels great to me.

Still waiting on the proper carbon wheels I'd ordered 6 weeks ago but just got the shipping notice. Anxious to get them mounted.

Sounds good. Mines sat waiting on a few bits to get it built up and debating whether to bother with heli tape.

I'm looking forward to that first ride, this frame is half the weight of stumpjumper fsr frame its replacing.

nice. is there plenty of clearance for the 650b? there looks to be on mine judging on the amount of room around my 26's. just thinking of future upgrades
