We have been riding our second stainless prototype around Calgary for the last 2 months and were supposed to report back on it weeks ago but summer has been really nice here for a change and well, you know how it goes…
The protoype is a 650B frame based on the same low trail geometry as our cro-mo 650B Velo Routier frame. .Like the Pavé Prototype, it is made from Carpenter stainless steel with a twin plate crown fork, disc brakes and 1-1/8″ Aheadset.
We stuck to the tried and true Velo Routier V1 geometry and made a few improvements to increase fender/tire clearance.
Top Tube 31.8mm Dia 0.7/.04/0.7
Seat Tube 31.8mm Dia 0.7/0.4/0.7
Down Tube 38.1mm Dia 0.8/05/0.8
Top Tube Length 550mm
Seat Tube Length 540mm
Chainstay length 430mm
Bottom Bracket Drop 64mm
Head Tube Angle 73 deg
Seat Tube Angle 73 deg
Rear Axle Width 135mm
It has clearances to accommodate 54-55mm wide fenders and braze-on fixtures to attach fenders and racks to. We fit up our prototype with 52mm Velo Orange Zeppelin fenders. A rfear fender attachment to the underside of the seat stay bridge was spec’d but missed on the fabrication of the prototype.
We deigned an all stainless steel with a twin plate fork crown similar to the Pavé. Unfortunately, the prototype is also missing the top of the crown fittings.
Bare frame weight is 1998 grams vs. 2177 grams for medium cro-mo VR 54 cm frame and the bare fork weight is 926 vs. 958 grams. Even accounting for the extra weigh of the disc brake fittings, it not a huge weight saving for you weight weenies but we think the ride is super smooth and frame is bomb proof ! With a bit of refinement, we think we might be able to shave another 50-70 grams off but not the at expense of durability.
The Pavé protoype is at Free Range Cycles in Seattle for the next couple of months and the stainless steel VR prototype should there in 2-3 weeks. If you are in the area, drop by and say hi to Kathleen. Give our prototype a good test wring out – we really want to hear your comments and suggestions!
