29er Plus

Posted: August 30, 2015 by Mark in Uncategorized

I recently completed a 29er+ build for a customer (and friend).

29er+ is an interesting tire format to supports riding in a wide range of conditions. It’s still a pretty new concept, a lot of people really enjoy this style of bike. The rims are the same size as a 29er but extra wide. The tires are also wide. It seems like the perfect thing for winter training. The frame can also be run with normal wheels so the setup provides a lot of flexibility. Eventually, I am going to build a 29er+ for myself.

    I love my 29er+ and built it up as a SS. When I was in shape, it was a fantastic training bike. It was ‘light enough’ and 3.0 tires at between 15 and 17 psi smoothed out the trail well. Only thing I did not like was the Knards. The traction was not great and you really had to run a low psi to take advantage of wide traction tread, otherwise even at 18-20 psi (with 180+lb rider) they were two rounded. I noticed that my contact patch was no different with Knards than with a 2.35 Schwalbe (maybe worse). It is nice that there are some more options for tires now. SInce I got fat and out of shape I put gears on my 29+, and then just last week, for the first time I took off the knards and put on 2.35 Nobby Nicks at 20psi. Definitely a rougher ride, but damn, I was a lot faster. Maybe it is also time for a suspension fork. :o
    I look forward to seeing what you build up for yourself.

    Were you able to maintain your standard 29er geometry with the + size platform?

      I kept it close to my normal geometry with 69.5 degree head tube and 440mm chainstays. The bottom bracket is a little bit higher due to the tire size and a goal of allowing the bike to be run with smaller tires as well. I will post the drawing of the frame later tonight.
