    Broken shifter question on Trek 720

    The left shifter had blown apart on my Trek 720 hybrid last week. It can still change gears, but it doesn't sound very good. Is the SRAM shifter a simple replacement on my 8 year old Trek or would it involve changing more connected items? I'm not a bicycle mechanic so I would depend on a shop and need to weigh the cost of repair.



    Thanks for the information.

    That is a not particularly difficult job. SRAM web site and www.parktool.com cover this in varied detail.
    I did find that on mine, there was an allen screw buried in the recess holding the cable head in place and not a spring clip as the SRAM site suggested. Took a close magnified eyeball to discern this. R&R is otherwise pretty straight forward. Nashbar was selling these in 8 and 9spd versions for $25 over the winter (shifters, no cables). I would replace cables and housings as well on an 8yr old machine.

    That doesn't sound like too difficult a job to do myself though it does have a 7 speed casette. Has the 7 speed gone the way of the dodo bird? If so, what are my options?

    You can use an 8 speed shifter with a 7 speed casette. You just have to set your limit screws on your rear derailler accordingly to keep your extra gear from shifting into the spokes.

    7-speed SRAM grip shifters are still available. I even recently bought 6-speed at Nashbar. But your pic looks like a front shifter so just get a new front one.
