Anyone here ever had an old Eaton's glider? I picked one up at a yard sale recently, and noticed that the brakes barely reach the rims in the highest position. I suspect the previous owner swapped out 650b's for 27 inch wheels. I think the bike is from the seventies. Here are some pics.
I never learned to ride a bike. It is my deepest shame.
themore common size for Eatons Gliders is (I think) 26X1-3/8, which has an ERD of 590mm, which would put the braking surface 20mm further down than 27" with an ERD of 630.
650B is not as common on North American bikes - it is a French size that has only recently found a following here.
The good news is that 650B has an ERD of 584mm and could probably fit better on the Glider than 27". You just need to find some tires that would fit between the stays. 700C wouuld also be slightly better than 27"
