| | Re: How tight should I tighten the sprocket bolts? I used 1/4" drive ratchet and tightened about as tight as I could with one hand. I didn't get brutal or anything just good normal tight. I started out with them just snug and went round and round tightening them trying to keep sprocket straight. Hope this helps.......................

| | Re: How tight should I tighten the sprocket bolts? I should have read the instructions that came with my kit instead of looking at those picture instructions from zippycycles.com ! The photo of the sprocket shows both rubber washers on the inside of the spokes, rather than one on the inside and one on the outside like my instructions say. I have a feeling my instructions are right, what did you guys do? |

| | Re: How tight should I tighten the sprocket bolts? The instructions I saw recommended a rubber washer on inside and outside only for bikes with coaster breaks. I'm not sure why that would make a difference.

| | Re: How tight should I tighten the sprocket bolts? Follow our instructions and you will be successful if you don't understand anything don't be afraid to ask. I use the fiber gasket on both sides to get a good grip on the spokes, keeps the sprocket off the spokes, provides space to aline the front and rear sprockets.

| | Re: How tight should I tighten the sprocket bolts? I agree its the only way that makes sense. Metal and metal will never grip like that wrap around fiber.
I tightened mine till I felt like the nut stopped moving, not till the puller handle bent. But you should check it now and then, as it will probably get loose after a while. Everything gets loose after a while | | Thread Tools | | | | Display Modes | Linear Mode |
