This Bertin was supposedly owned by a California bike shop owner’s wife. Based on its overall condition it looks like it was only modestly used, but very well cared for. The bike is nearly 100% original with the tires being the only update I can see.
How’s it ride? Well, from my short time spent on it, I’d say just about typical for a lower-to-mid range 1970’s bike. I don’t feel a lot of difference between the Bertin and, say, a Peugeot UO-8; that is, with the exception of the rims. Where most 70’s bikes ran soft, heavy steel hoops, the Bertin has wonderful aluminum Milremo rims. It might seem a small upgrade, but the wheels do feel stiffer and braking is much more “grippy” (see, “much less scary”). …And though the rim sides still have perforations, they don’t have the jet engine scream of textured steel rims. The Milremos sound more like a modern business jet as opposed to a Century-series fighter.
If my research is correct, this Bertin is a model C31. Hopefully someone will chime in if that’s not right. It wouldn’t be the first time I’ve been wrong, nor the one-thousandths, nor the millionth…
(Thanks to the gang at the Reno Bike Project for providing both parts and some really special bikes over the years.)
