The Polyvalent has been our longest running frameset, going back almost eight years. It started from humble beginnings as a cantilever-braked, low-trail city bike sporting nondescript matte-black paint with orange decals. The Mark 2 and Mark 3 versions got new paint jobs, updated tubing, better accessory mountings, and other evolutionary changes. Now it's time for version 4.
The prototype frames made it just in time for Philly Bike Expo. We had lots of great feedback from folks who saw it.
- Increased tire clearances: 47mm tires with fenders. And new (57mm or so) fenders will be available.
- Normal fit: the original Polyvalents were designed with long top tubes for upright bars, but if you wanted to use drop bars, it meant less-than-optimal fit for most riders. The new version will have a shorter top tube and the same fit as our Campeur and Pass Hunter.
- Internal rear brake cable routing: Same setup as Pass Hunter Disc, internal tube for easy and clean routing.
- Triple water bottle bosses on top of the down tube. Tall bottles, easier to reach bottles, big bottles.
- Wrap-around seat stays: because they look so good and provide wider seat stay clearances.
- Vertical dropouts with stainless hanger: Sliding, swinging, and alternating dropouts are solutions that add significant complications to construction and still only work for some applications. Use a chain tensioner if you need.
- Head tube re-inforcements.
You may have noticed that there's no fork. It wasn't ready in time, and we are considering using a new custom VO fork crown on this and some other future frame models.
Tubing is double butted 4130 chromoly. Downtube is 31.8. Top tube is also 31.8 for better control with loads, though we may go with an ovalized top tube depending on how testing goes and if planing is adequate.
We're really excited to have the Polyvalent back in action, and look forward to R&D rides with the VO gang!
