Derailleur upgrade

riki652

I bought this bike https://keindl-sport.hr/cube-ltd-pro-29-blackline-2015-proizvod-5608/
and i don't like the chain slap, so which one of these derailleurs would best fit my bike.

This is the one I currently have http://www.chainreactioncycles.com/hr/en/shimano-xt-m781-shadow-10-speed-rear-mech/rp-prod83163

You need a shadow plus (10) mech of the same length cage.

Although just fit a chain stay protector and be done. Works for me.

Its not the dirt on the bike that annoys me but shifting on bumpy terrain sometimes skips a gear because the chain is jumping around hard.

I didn't mean for dirt, I meant for noise.

Never found that problem with my non-shadow XTR setup.

Is it skipping at the front or back?

Never found that to be a problem with any mech.

So possible incorrect indexing, chain too long, or using small/small over bumpy stuff.

Sometimes the front gears skip

so sort the front out rather than the rear. Plus mech stop most slap but make gears a little more clunky and don't do a great deal for front retention on its own.

I'd disagree, makes a fairly big difference in practice. The way my old bike used to drop off the larger front ring over really rough stuff stopped completely with a clutch mech. Was more down to an older suspension design than anything else.

If it dropped off the larger front ring then, you had a front mech then? That would have been the device that did the 'retention'.

When I say doesn't do a great deal on its own I mean it's more of a pronged approach in that you have the plus, a NW, some type of guide and a bash for the belt and braces approach.

But personally never had a problem with a correctly set front mech. But I'm not that hardcore.
