I bought a Shimano RD-M772 Derailleur fitted it onto the bike in place of the X-9.

 

Set it up etc and if you press the lever up to first gear the derailleur is in first gear when the dial on the quickfire lever says it's in 3rd .

 

I went back to the shop and asked him if he had sold me the 7 gear one as mine is a nine gear cartridge. He reckons I set it up wrong and to try again.

 

I did and its the same, now I am thinking the Shimano is not compatible with my change levers.

 

Put my old derailleur back on and set it up, perfect, no probs

You will need a new shifter, lbs should have told you, SRAM and Shimano have different actuation ratios. Any particular reason for the switch?

 

The guide rollers on the deraleur had teeth missing so me being me decided to stick a complete new deralleur on, the guy in the shop didn't stock sram so gave me a shimano.

 

Took the deralleur back the other day, told him he didn't have a clue and went somewhere else and got some new guide wheels as a spare, cleaned and service my sram X-9 and it's good as new, just had to get a new chain and the bike feels much better. I feel happy with it now.

 

Just had to put some extra psi in the front forks as I am nearly 16st and the lad I bought it from couldn't have weighed more than 5st wet through , I must point out however, that my 15st of my 16 is pure muscle, the other stone is my manhood :001_smile:

That doesn't leave many ounces for brainpower!:001_smile:

 

You need to find a good bike shop that you can trust (I used to work in a fairly major one) and now would only let one of the 12 staff there touch my bike, the rest are muppets.

 

You will probably want about 40psi in the tyres for general riding and 25-30 if you want some traction, I run about 18-20 off road but I am only 10.5 stone.

 

Any more problems?

 

Heres a pic too, never looks as steep, sketchy, rutted, loose, in the pics.

Not sure if this has been mentioned but going back to your seat pal, Instead of getting a comfier seat, Buy some shorts with a padded arse, they make the ride so much better, The seat on my scott is a killer with normal shorts on but the padded ones on its comfy.

 

Dont know if you have a decathlon sports shop near you but they do them for £20 mate, :001_cool:
