spin it!

i thought of you today as i replaced a broken mech hanger and mashed mech on an aggressor...

That's funny because although my rear mech thus far has been fine (touch wood), I've had the chain try to come off several times whilst changing from teh middle to the largest front chain ring. Apart from the first time, I've managed to catch it before it all goes off and a quick back pedal later all is well, but it does plant doubt in my mind every time I go for that switch, as it usually means I'm not far off going as fast as I'm capable of.

technical advice: if your front mech is in danger of throwing the chain off the top ring, then the mech needs stopping down a bit, there are 2 stop screws on the front mech - get your chain up to the top ring and turn the one (trial and error but it's probably the outer screw) clockwise to pull the mech a bit nearer to the chainring so there's no play when you switch up, it shouldn't kind of swing out and back, it should stop dead above the ring. you may also need to take up a little slack from your cable as it will probably have stretched by now.
Also remember correct gear drill - small ring for the three lowest gears, middle ring for the 3 middle gears and big ring for the three toppest gears to avoid the chain "seesawing" and incurring unnecessary wear and tear! happy riding!

Thanks muchly kind sir!! :)
