650b single speed wheelset

[Stephen Durfee]

Longshot ask, but does anyone have a pair of 650b SS wheels, possibly take-offs from a small Roaduno build?  I have an older Peugeot PX10 frame that I think would make for a fun knock-around bike.

PX10s as singlespeeds are fun knock-around bikes. I just use redished 126 OL 700c wheels but 32mm rear and 35mm are a snug fit and forget about fenders :) so I guess that's why you're looking for 650b.

Good luck on the search

I have two right now for sale -

old take offs from a Quickbeam, Velocity Synergy rims to old Suzue hubs

black velocity quill rims with a Kasai dyno hub and black Phil rear hub 

LMK if you're interested in either

I have a 650B wheelset (rear with 135 Surly flip-flop hub and Soma Weymouth rim, front new Weymouth rim and new Deore something front hub) if anyone can use it.

Can you list them in a new post?

I’m interested, but I don’t think they’re 650B and I’m not going to play a guessing game on prices.

Kinda regrets selling his QB wheels in California

@Stephen, interestingly enough a Stephen came into RBW with a PX10 asking if 650B wheels would fit. Was that you? Answer to the question is in RBW's weekly email . https://mailchi.mp/94f2c9129b95/pine-tar-soap-on-a-rope?e=0074b52ae1

Rumor has it that the wheel sets that Calvin is selling are also sitting there at Riv HQ.  Worlds are colliding!

Little did I know that I would reach internet stardom via the weekly email...or that it was Grant/Rich's birthday...but I did leave Riv HQ with a handsome Bicycle Fan Club T-shirt, as well as some helpful insight. Will was kind enough to pull out a 650b wheel for testing the fit. As reported, the current brake set-up would need to be updated. Thankfully, I've gotten several responses to my initial post, and a few folks have offered brake solutions as well.
