This Boyes and Rosser Cycles Sierra came from West Point Cycles in Vancouver. I'm really guessing at it being an '88 model because I bought it along with a 1988 Rocky Mountain also from West Point.
Other great old features; colour matched stem and handlebars, albiet in a screwball setup. Short and very tall stem with a narrow bar, which was the style at the time, of course. I'd say this frame is a medium, meant for someone 5' 9" at most. At 6 feet, I can ride it, but it's cramped. I'd need a longer post and stem to be comfy. Biopace chainrings, which we all laughed off the market back then. Science brought them back, for some road racers anyway. And check the all-plastic Wellgo pedals with white bodies and black cages. They spin very nicely.
It really feels like this bike has less than 100km on it.
Seems that nobody knows who Rosser was. I found a post from someone that worked there in the late 70's who said the staff all joked about Rosser being a fictious racer maybe?
Anyway, I'll be putting this up for sale here, and be lucky to get $60 for it. Which is kinda sad as it's perfect; the index shifters work, the brakes feel good, and it rolls smoothly. But it's ultimately an old bike that's not a well-known (and therefore not sought after) brand, and even though I'd rather have this bike than a brand new, $200 bike from a box store, I'm in the minority on that desire.
Normally, I'd want to fix up the cable housing as it's way too long, but it's not going to make it worth any more, so why waste my time on it? I have a ton of other things to do, which I'll let you know about soon.
