JohnyMilton Posted July 24, 2007 Report Share Posted July 24, 2007 Hello people!I have decided Im going to use gears on my trials bike, but I dont know what mech to use, what I mean is what size of cage short or long. So who ever runs gears what cage do you use. Im kinding of thinking of a short cage, for more clearance but I dont know if its a good thing. I use a long cage on my freeride bike, because the gears will work faster, but Im not sure if I need more clearance or fast reacting gears.Someone please help! lolJohny!

Janson Posted July 24, 2007 Report Share Posted July 24, 2007 Road mechs are optimal for trials bikes.I used a Shimano Tiagra. It was OK. Some people used Dura Ace mechs some years back. Expensive but pretty and light.So yeah, short cage road mechs are great. The cassette cogs are so small, and in combination with only using a single small sprocket up front, you can get away with a short cage mech. You can lock it out too by removing the spring around the bolt that mounts it on the derailleur hanger, which prevents the mech from banging on the frame, while still shifting gears well.Removing the spring on a Tiagra mech (probably very similar to all other ones) is done by first removing the C-clip on the back of the main bolt (the one that mounts the mech to the hanger). then remove the spring washer thingy, and then remove the spring. Bolt the mech to the hanger with the spring washer thingy on, but not the C-clip. Voila. Quote Link to comment Share on other sites More sharing options...

robb_o Posted July 25, 2007 Report Share Posted July 25, 2007 I've got an ONZA short cage rear mech and I recommend it! (It's much better than the XT one I used to have).It's INCREDIBLY short, and cheap, and the springs are nice and firm.Got it off Tarty.

darrenhopper Posted July 25, 2007 Report Share Posted July 25, 2007 Couldn't agree more! Short cage for the win.Couple it with a road cassette & you should be very happy. That way each gear change will only change your ratio by one or maybe two teeth on the back. Quote Link to comment Share on other sites More sharing options...
