I tried to adjust the cable tension but there it litterally no way to adjust it on the front derailleur on a 22.5" GMC Denali 700cc Men's Bike

  • Can you provide a clear photo? Use "edit" just below your question, to add one or two photos showing the shifter and the front derailler. Could be there isn't a barrel adjuster for the front gears - My road bike doesn't have one. I have added a generic photo from walmart.com – Criggie Sep 24 '16 at 23:33

You might not have one. Check near the place where the cable exists the front shifter or on the cable, but on a BSO like this, you most likely don't have one.

Your options are to install an (inline) barrel adjuster or just do the adjustments without the barrel adjuster (which just allows for fine tuning, really -- you can do all the adjustments without it, but they will be finickier).

  • Sorry answers don't show when doing reviews, so I missed this. Is it possible there's some adjustment in the brifter? Or is the trim feature priced above this bike? – Criggie Sep 24 '16 at 23:44

    They aren't built with brifters. They have regular MTB twist shifters installed in the center of the bar (I'll let you work out how they do that). – Batman Sep 25 '16 at 0:04

    @batman - I read somewhere a while back that there were a number of BSOs being made where the drops were welded to the bar after a grip shifter was installed. This could be one...... – DWGKNZ Sep 25 '16 at 7:07

    Criggie - The bike costs about as much as a pair of off brand shifters (e.g. Microshift). DWGKNZ - What I've heard is that the bar is cut in the center (where the stem clamps) to put on the shifters). In any case, I wouldn't trust the bar with that installation mechanism. – Batman Sep 25 '16 at 14:01

    Twist grips! OMG. That's really putting "bicycle shaped" to the test. Talk about designed not to be maintained. – Móż Sep 25 '16 at 21:44
