love2fly Posted August 12 Share Hi Hubbers My son recently bought a Scott Spark 940, aluminium, circa around 2018 and I'd like to replace the shift cable housing - before I pull the old one out does anyone know if this bike is likely to have in-frame guide tubing? My Cannondale Supersix Evo doesn't and that caused me some sweat.... Cheers Link to comment Share on other sites More sharing options...

What you can do is use a piece of "Bloudraad", bend it slightly and feed around 50-60% of it into the old housing (At the bottom - above the rear mech), then the rest you feed into the new housing. By slowly pulling and pushing you'll be able to feed the new housing through the frame. Prince Albert Cycles and love2fly 2 Link to comment Share on other sites More sharing options...

Jehosefat Posted August 13 Share Alternatively, feed a new cable through the old housing then pull the housing out leaving the cable in place and feed the new housing over the cable that's now in the bike (or if the old cable is not too frayed you can just pull the old housing off and feed the new housing onto that cable, then replace the cable). I've found this works pretty well. bullet77 and love2fly 2 Link to comment Share on other sites More sharing options...

I've found this works pretty well. Yip, that had occured to me but on my bike I've battled to get the housing out the chain stay as the shift cable is a bit malleable. But certainly a plan B. Plan C will be taping the housings together ... Link to comment Share on other sites More sharing options...
