I've started getting chain slip at the back if I am out of the seat and I hit a root, or kurb, or something like that. I've heard that worn jockey wheels can cause this, so could that be the problem?

But I was thinking, instead of just replacing the jockey wheels, I might as well buy a new rear mech, as mines a 18 month old alivio (sp?) that came with the bike. So would a LX be a good balance between price and performance, or should I go with deore or XT?

Thanks

IMO LX isn't really worth it, Deore is good, XT is better, but more expensive. You pays your money and takes your choice.

I doubt it's just jockeys causing that problem though, they dont have the ability to shift the chain, just stop it shifting if you know what I mean. Your chain can't really 'ride' up over the jockey wheels like it can the chainrings or cassette too.

it's acera :-P

if you're willing to spend the money, get xt, if you're likely to rip it off on a tree, get deore

if you just want something that works well and won't make you cry in the event of an accident, lx would be good :-)

get some nice cables while you're at it

do what nick says, he knows all

Haha, well I am a sort of oracle certainly :-)

I just think that LX is a bit of a 'not one thing nor t'other' group. XT offers clear performance benefits and does weigh less, than Deore, but LX is a tiny bit more expensive than Deore, with minute gains.

I'd go with Mike's advice, if you feel flush- XT, if not, Deore.

Deore it is, with some nice new cables (inners and outers I guess would be good)


And mike you are quite right it is Acera, but I'm never quite sure because I try not to look at it too much, the amount of crap on it's depressing

Hmmm, just realised that didn't really solve the problem of the chain slip, any ideas for that?

How old's your chain/cassette?

couple of months, shouldn't be the problem, fairly clean too...

rings?

New chainset, last week

[Edit] so could that be the problem?

Unlikely,as the chain/cassette are only a couple of months old. Hmmm, hard to say to be honest. I just think it's unlikely to be your jockey wheels.

Oh well, I'll get a new mech anyway and see what happens

I think Deore is better than LX, loads of others say this aswell to be fair.

LX is normally on wiggle for £25 discounted or £30 for Deore, why I normally get LX.


Acera for me next time, out live every other part and rips trees outta the ground unscathed :) ( does weigh 4tonnes LOL )

I've had an Acera rear mech on one of my commuter bikes for seven years with no probs :-)

acera are good untill you snap one

wait.. that goes for all mechs!

i rigged up my own mech using a coat hanger and some pulleys cost £1.99, bloody marvelous, miles better than XT.

...and lighter too eh Smidge ;)

much...


God knows why any bent fag would spend £100+ on a mech when you can have a bent coat hanger and some pulleys for £1.99.

Bent coat hangers rule, I use one for drying out me camelbak bladder. Beats paying £15 for thier version.
