sram dual drive

It is a Sram dual drive hub with 3 internal gears and a 9 sprocket cassette and disc brake assembly. The first internal gear, that's the high torque low speed for climbing steep slopes does not engage. The other two positions for level and downhill work OK when shifting. The Click Box is properly aligned at the 2nd middle gear position as per instructions. Understand that the 9 sprocket cassette coupled with the three internal gears of the dual drive will result in 27 separate speed combinations. In this case, the low internal gear not engaging, freewheels the entire cassette, resulting in only 18 operational speeds, not the 27 nominal that it has been designed to do. I need your advice to correct it. I have to walk the bike for steep hills... Thank you.

The first thing I would suggest is that it is out of adjustment, but since you say that "the Click Box is properly aligned at the 2nd middle gear position as per instructions," it seems you have already checked that. I don't have any more knowledge about the system than that. It sounds like you will have to bring it to a dealer. Before I did, though, I would separate the drive from the shifter to try manipulating each manually and isolate the problem into one or the other. Sorry I can't help more. Best of luck. -AndrewDressel (talk) 12:44, 9 August 2013 (UTC)[reply]
