These are flat Shimano thumb shifters, not the ones that stand up. Terrain in Gulf Coast Florida is flat with some bridges and rolling hills.Īm grateful for your comments and your prompt reply, thanks much. English Raleigh 20-30 quality of the period was decent, I rode a GP for years and a Competition, but I dont disagree with your comments. Everything works fine and I dont plan to change the freewheel or the derailleurs the Steel rims are in very good shape.
So that's what I need help with at the moment. I've bought Shimano bar shifters - cheap and simple, provided I can find a way to route the cables off the downtube - have found used Simplex guide but still have to get the cables to the bars. Bike, tires, and gadgets will total about $150.00. I have new tires coming, and will strip&paint frame (metallic blue Oldsmobile colour), perhaps buy decals, maybe pedals&cages, and add new HB tape. I've identified the frame as late 1969 female Grand Prix.

How much weight will the bike be carrying (you plus all the gear you will take along)? I would change the brakes to Tektro dual pivot side pulls the rims to ISO 622 Velocity Dyads, Wheelsmith spokes, New tires, tubes, and - might need a hanger for your application Of course, before doing all of the above I would get a lugged double butted 531 or Cro-Mo frame. Where and how are you going to be riding it? Flat lands, hills, etc. Use this: to help you get a better idea of what year GP you have. The frame is 2030 steel, which can be cold set, but is a bit stiff for opening up 5mm on spring action.
You may be able to get a 130mm OLD hub in there without cold setting, but I doubt it. To go with a cassette will require a new rear wheel - AND cold setting of the frame.

This is a NICE Henri Selmer Grand Prix or Grands Prix Cornet made in Paris, France.With its serial number of 401, we believe this cornet to be built in either 1932 or 1933.This cornet is a VERY nice piece, with perfect valve & slide action.ĭo you want shifters integrated with the brake levers (aka brifters), or at the bar ends (bar cons)? Your bike currently has a freewheel, not a cassette. I believe that the GP came with stem mounted shifters. What is your budget? And pictures are required. It sounds like a refurb/update project, not a restoration. First layout a complete plan of what you are trying to accomplish.
