    79er SS rigid?

    I just got a 29" front wheel for my 650b bike to try this out. Anyone have the same set up? It seems like it should work great for SS rigid.

    What advantage do you feel it would have over a 29er or a 650b? Seems like extra non compatible parts (tires, spokes) to me. Good luck with your experiment just the same

    79er SS rigid?



    I'm not sure how much gain there'd be with 27.5 to 29, but on my 69er the improvement gains were substantial. Just make sure that increasing wheel diameter doesn't blow out the handling of the bike with respect to maintaining head tube angle with A-C length of fork. I went with a shorter length fork to compensate for the increase radius of the 29er wheel. It handles like a dream now.

    I went with a shorter niner rdo fork, I'm hoping it doesn't get too slack. I'm gonna check it with an angle level after I put the tire on. Cool bike

    I know a handful of guys that ride this setup on their fixed gear mtbs. I have really bad OCD when it comes to symmetry so I could never do it, but they swear by it.

    Its seems to make sense as long as the geometry doesn't get messed up too much. Good rollover and some extra momentum of the 29" and quicker acceleration of the 27.5" maybe.

    I think the benefits are largely non-existent. Like going from 170mm cranks to 172.5mm cranks. Most would not even notice.

    Nothing bad to say yet, kinda icy on the trail to really determine much though. I think I'm trying to make a trail/XC bike. One that will climb like my old bianchi sass but go downhill quite a bit better.

    Nice bike - Shan or Oka? Shan, I presume. I've been riding 69er rigid singlespeeds for the last seven years, mostly a Singular Hummingbird, which I reckon is the best handling bike I've ever owned.
    So, I'm a big fan of the whole unequal wheel size thing - haters always gonna hate but I could care less. Liteville have it right - " front wheel as big as possible, rear wheel as big as necessary".

    Thanks, it's an Oka. I can't wait for the trails to clear up a bit to get a better sense of the setup.

    The improvement is going to be slightly less noticeable than with a 69er but I think it'll still be good. It looks good anyway and" if it looks right, it is right"

    79er SS rigid?-69er-001.jpgI'm kind of on the same page as you are. Currently have a titanium Kona Una 69er and would like to jump onboard the 27.5+ bandwagon. LOTS of room up front on my White Bros Carbon 26" fork could probably get a 3.25 650B tire in there at least a 3.0 no problem. The pic is with a 29" front wheel.

    I've been chompin at the bit to see what the 79er ride is all about. We need to warm up and melt around here.

    I tried the 650b rigid fork that came on the bike, but that felt too slack. I put a 26" fork on and now we'll see.
