Update: Polys may be in stock later this year. See comment from VO attached to this post.
My Boulder Bicycle All Road is a lovely 650B randonneur frame that’s well priced in terms of quality/function, but it’s not a cheap option for someone who wants to try a low trail 650B bike out. The Velo Orange Polyvalent is a deal at $400.00 for the frame/fork or $595.00 for a kit that adds wheels, seatpost and brakes. One of the local BC randonneurs rides a Poly and it looks like a lovely bike.
The only issue that concerns me is how to deal with full coverage metal fenders and the forward facing horizontal dropouts? Metal fenders don’t have a lot of give so you’d either have to install them with loads of clearance which may not even be possible using 650B x 42mm tires or letting the air out each time you remove/install the rear wheel. The later option may not be such a hassle seeing as I would be unlikely to remove the rear wheel unless I got a flat or I was overhauling the bike. Hopefully neither would happen frequently.
A few Polyvalent notes:
- horizontal fwd facing dropouts allows for derailleur, IGH or fixed/SS drivetrain
- TT is very long for frame size to allow for swept back bars
- kit seems like a decent deal
- Polyvalent product info is here
- geometry info is here
Don’t get too excited about buying one of these frames though. I asked VO when they’d be back in stock and the response was 2012 – that could mean Dec 2012! Rawlands Cycles has a couple frames that may work for your 650B builds. The Drakkar has a 50mm fork offset with 73 deg HT angle and runs only disc brakes with rear facing horizontal dropouts. The rSogn has 63mm of fork offset with 73 deg HT angle and runs rim brakes with vertical dropouts. Both Rawlands frames sell for ~$600.00-$625.00 even better Rawlands has some stock of Drakkars and the rSogn is available in the near future.
