Hi cycling fans ... I am restorate a Japanese SAKAE Litage out of Aluminum tubes from the begining of the 90s - someone an idea, where I can find to buy these 2 transparent inserts for my WIP SAKAE Litage
If you can't find them in the usual places (eBay etc), I would look at drawing them and getting some made. They are called resin dome stickers I think. If you have to get a minimum order you can then sell your spares to other needy restorers!
Had one of these frames years ago and they are good things. Really the only chance you have of making this good is go the way zerogravitas suggested.If you find the real thing in years to come you can allways swap them but to be fair you have very little chance
