Well, fate dealt her hand in the end
I was a bit nervous about how much a 29" was going to change the geometry, as i've said before.
Dan, our freindly neighbourhood wheel builder, had been on a boat off Greenland until about 2 weeks ago, so the wheel lay unbuilt at his place for a bit.
When he came to build it he discovered CRC had sent a 650b rim instead of a 29"
Initially i was annoyed about CRC's cockup, and i sent them an email explaining this
but then i realised they had done me a favour
650B is 27.5", so halfway between a 26" and a 29". So i now have some of the benefits of a 29" without loosing any of the benefits of a 26"
Just need a matching Racing Ralph in 26" for the rear now and i'll be more than happy
The older I get the faster I used to be......
