Rear Suspension measurements

Help!

How do you measure a rear shock so you can buy an upgrade??

I am new to full sus rigs (old school hardtail previously), but wanting to upgrade. In order to upgrade the rear shock, I need to work out the size to order …… HELP!

Thanks

eye to eye (c-c) measurement (when uncompressed) and travel stroke I think are the main ones.

you need two numbers, eye to eye (centres) and stroke length. ie 190mm i2i, 50mm stroke is a popular one.

hi was thinking the same question the other day

can do it the top way, after working out how far it compresses
but suppose you can measure the eye 2 eye length of both compressed and extended and the difference is surely your stroke length

FANTASTIC – Thanks guys

What bike is it ?

the i2i length with the stroke length are a start but you also need to know the width of the shock eyelet and the internal width of the frame mounting points where the new shock is going to sit(incase you buy a different brand of shock, because manitou and fox use a different diameter eyelet so therefore you would need new bushes to fit)

have a look here…it explains everything you need to know

Think they are distributed by Fishers, ask them for exact details.

worth phoning mojo to find out what compression and rebound tune works best with your shock as well as each one comes with three levels of tune depending on your frame, i have two turner 5 spots one with push (long) rockers and one with stock rockers and the pushed one works better with a high tune and the stock one works best with a medium tune, worth a phonecall to find out imo
