MTB 10spd drive trains - Wear and Tear

[TNT1]

My mechanic at my LBS told me not to go for 10sp as you chain life is approx 350km

where 9spd is closer to 600-750km

 

 

Get a new bike shop and a new mechanic. You should be getting much better life out of a nine or ten speed drivetrain, and there should be no difference between the two.

Good question this.

 

I have just replaced my SRAM PC1071 chain after 2 months use (exactly on 0.75 mark) - around 800km or so I think, which I found to be a bit low. My previous PC991 9-speed chains lasted around 4 months (so say 1500-1800km) if changed at the same wear point (0.75).

 

I'm not sure this is something related to 10 speed though and could just be a "Friday chain" I got. I also could be changing it a bit on the early side, but every time I've held on until it reaches 1% its too late and I need to replace the cassete as well. There was a bit of extra mud riding involved too, so jury will stay out into winter and we'll see how things are in the dry.

 

Having said all that, with CW Cycles' prices of R450 and R550 for an "X9" chain and cassette respectively its probably worth riding them both into the ground and keeping a spare of each. If you're on XX or XO different story entirely!

well I've just recently changed to XO 2x10 and already put 600k on them and not a slight bit of a problem.
