I've spent about the last 4 weeks failing miserably to source a new schrader valve for my rear shock and refuse to pay £80 for a shock service just to have a new 50p valve put in when new shocks can be had for around £100.
The shock is an X-Fusion 02RC fitted to a Specialized FSR XC. According to the Specialized site it's 7.5" length with 1.75" stroke/travel. I make that 190mm by 45mm. I can't see anything else in that size but can see lots of 190mm x 50mm shocks about. What's the upshot of using a shock with 5 mm more stroke?
Is the shock travel to wheel travel ratio linear or does it change towards the end of travel? If linear then it looks like 120mm goes up to about 133mm with a 50mm shock, but I fear I'm over simplyfying things...?
What other things should I be worried about? BB height? Corresponding fork travel (currently 120mm)?
Ideally I'd like not to have to replace the shock, but I'm just considering my options
