61 Corvette Hub Swap-coaster to 3 speed

How close are the spoke lengths between the stock coaster hub and a Sturmey 3 speed hub?

Not the same. There is a thread for sizes, what type of rim are you putting it on? S-7 26 inch? I will look around but it out there somewhere.

yes, an S7 26" rim. I either want to swap the stock hub for a 3 speed or use parts from a trashed Breeze with the same color blue I can use the fork, fenders and wheels for the Corvette. The 597 wheels/tires fit fine underneath the Corvette's stock fenders.

I found if you bring your rim and hub to a bike shop they can cut the spokes to length for you. the formula to determine spoke length is online if you want to figure it out yourself. it only cost 5 bucks for the bike shop to figure it out so that's what I did. I went in with a spoke and they said the length would not work with the shorter nipples they had, so they had to make them a tad longer.

I have a 1959 corvette 3 speed, I have some things to do but later I can probably find the spoke length. i think it is same size as needed for 2 speed hubs. 49 has a good point if you are going to have bike shop build it let them also figure out spokes. Are you planning on building wheel yourself? I will look later for length. The breeze is not an S-7 i think S-5/6

I can do some more looking but I did find something from Gordy. He quoted a torrington guide in another thread it called for 10 5/8 done 3 cross.

 

[Siestabikes]

yes, i do my own wheel building. thanks for the measurement, junkie.

Those parts off a Breeze won't fit a middleweight, at least correctly.

I can use the fork, fenders and wheels

What is wrong with that fork? Also the fenders on your corvette are most likely SS I would keep them at all costs. GT is right none of the parts will fit.

If i use a 3 speed hub i need to have a hand brake. the Breeze front fender is drilled for a brake. the fenders line up ok and will need to be drilled to be mounted rather than using the existing tabs. i much prefer multi speeds over coaster brake bikes but the more i think about it, the more i may not do it. i converted this coaster Columbia to a 5 speed so this may satisfy me for the time being
