    New question here. SRAM S7 - can't feel no ratio passing the 1st 3 gears, and it suddenly goes up on 4th

    Hello,

    I've been reading S7 issues for 2 hours and couldn't find anything about my problem. Here it is my : I'm mounting a Bullitt bike (2 wheels cargo bike), which was delivered with a SRAM S7 hub (with coaster brake). I had no trouble mounting it except that the frame was made for a derailleur gear system? That meant (besides the chain tension problem) to pass the cable without the sheath and cut the sheath so it fits nicely in the spots on the frame. So I had to dismount the cable, and remount it in the click box. I thought I had remounted well, but who knows where that problem comes from :

    I can change all the gears, but don't feel any difference between gear 1, 2 and 3. Only when I go to the 4th, it becomes a much biger ratio. Then it raises up till the 7th, and back down the same way. Since I never rode such a hub, I wouldn't know what's the normal behaviour, but it seems weird not having ratio between the 3 first gears.

    Does anyone have an idea where that comes from?

    Thanks in advance for your help,


    Jérôme; Belgium.

    Hi Jerome, not sure if you sorted this issue as it was nearly 4 years ago however for anyone else who has the same problem - you are probably missing the rod that slides inside the hollow tube, which in turn moves in and out the hub axle when changing gears. I had the exact same issue then realised I had dropped the thin rod part on the floor forgetting to reinstall it.... took the clickbox off again, reinstalled the rod inside the hollow tube then reinstalled the clickbox and adjusted the gear indexing in gear 4 - SORTED! Hope that helps.
