Rear Derailleur (RD)

[Aul Han]

So a while a go I got new shifters and cables, got it set up relatively quickly and didnt pay much attention. Sow when the gears started playin up I put it down to lack of attention by me.

The X9 RD works really well, never misses a shift, until recently. Ive been cursing the derailleur in and out of hell for two nights... trying to set it up.

I recently replaced the mech hanger - well a few months back anyway - so it couldnt have been the source of trouble it... Could it?

Yes it bloody could, and was! And I was very :annoyed:

Thats two this year!

Im always gonna hit it so what can i do to stop this???

[kylemalco]

buy a road bike?

Avoid hitting sh*t with your mech?

Some are quite soft, I went through 5 in a year on one bike, then none in 18 months on the next, same type of bike same trails etc

Would you rather replace your hanger or your frame though?

Dont know how effective these http://cgi.ebay.co.uk/Massi-Rear-Derailleur-Protector_W0QQitemZ260459349379QQcmdZViewItemQQims xq20091105?IMSfp=TL091105187002r21825 are but my specialized enduro came with a similar one as standard and i never had any bother. Might be worth a try for a tenner

Did both in the end :D

Auld Han You want to try ripping your rear hanger in two , the chain cutting through the cage of a now badly bent rear mech and bending and twisting the drop out on the frame all on an Innocuous bit of Kirroughtree, and then no bike for 2 weeks :( much worse than the £20 or so for a new hanger.

PS i don't think Kirroughtree lends itself too well as a pump track

for solid hangers try betd goldtec stuff, hard as nails bit more pricy than a regular hanger tho

or you could go for my favourite option which is to just go shimano, even a standard style one seems to have a lower profile than the sram, especially in the lower (larger) gears.

x9 mechs stick out quite a bit, also watch because the parrallelogram linkage is quite soft around the pivots so you can dinge it which can restrict the range of movement of the mech (easy enough fixed tho)

Sram have addressed the sticky-outness for 2010.

Looks like an older sram mech thats shrunk in the wash, works well

[the goat]

so they have too, looks a better job, then id say get that wired on :D

[Aul Han]

Ill have a look at that protector but for now just stick a new hanger in there.

I like the sram shifters and RD tho, never had any issues. The Front SRAM Derailleur failed pretty bad on me tho, so stuck an XT on there - great job.

As JJ says maybe I should just try and stay on the bike!

[barry_kellett99]

I'd be wary of putting on a stiffer stronger mech hanger or anything to stop them bending, surely them bending is a design feature?

If you put something on that stops it bending, where does the force get transferred to? The frame?

I'm not sure, maybe someone with a cert in something relating to it would know better.


My only useful advice is to go with JJ on this and stop falling off, or at least learn how to fall off with some grace.

Failing that, SINGLESPEED

'Aul Han'.. you don't even know what it's like mate! In the last year, im on my 4th mech hanger and have just recently bent my 4th rear derailleur, as well as breaking one front derailleur..
Really not good! :'(

[Aul Han]

Solid hanger might do away with the whole point of the thing. Its cheaper than a new frame I suppose.

Your not havin' much luck Monty!

Surely there are one (http://www.rohloff.de/en/company/index.html) or two (http://bike.shimano.com/publish/content/global_cycle/en/us/index/products/0/alfine.html) other more effective options worth considering.

[drummerboy]

What about a mech hanger alignment tool, never used one before but i got my mech hanger straightened once or twice before, it sorted out all my gear problems.

I saw somethin like that in Belvoir a long time ago, not sure whos bike it was but it was internal gears.

Not sure if this would work on mine as its pretty mangled. But if its worked for you in the past there must be somethin to it...

Update: Hanger is purchased, bike will be back out asap!
