    7 speed friction shifter, 9 speed cassette

    Hey there,

    I've been trying to make the above work on my xtracycle - should I just give up one gear out back (no biggie,) or is there hope of being able to use all 9? I've got Suntour XC Pro shifters mated to a SRAM X7 rd and a SRAM cheapo 9 speed cassette. Any input on this would be appreciated. Thanks!

    Friction shifters don't have "speeds" and most have plenty of travel to cover a 9 or 10-speed cassette. It sounds like one of the rear derailleur's limit screws need to be adjusted depending on which cog it won't access.

    Exactly. On my "commuter" bike I'm running SunTour friction shifters with a SunTour rear derailler driving a Shimano 9-speed cassette. It take a bit more finesse to get the right gear (it doesn't take as much lever movement to go uo/down a cog), but it works just fine. Get the bike on a stand, shift to about the middle cog, back out the limit screws, then <<<carefully>>> shift to the largest rear cog. Tiny movements of the lever until it gets there. Now gently turn in the low limit screw until it just touches. Do the same going to the highest gear. Check to make sure you can reliably get into the cogs at both ends, making little adjustments on the limit screws as needed, and you're good to go.

    kotts and hillrider have it spot on. limiter screws are likely. if that don't cut it, shift the shifter into "9th" (smallest rear cog) and check cable for excessive slack and if so, readjust and try again. good luck.

    You'll also need a 9 speed chain and if you have front chain rings you could have an issue with the ring spacing and the 9 speed chain sucking between rings.
    It may not be fancy but it gets me were I need to go.

    This will not be an issue. I have 105 9spd and the front brifter works fine with my 70s-80s vintage Sugino crank. No chain suck.
