rear shock query

brett1980

Hi,
I have a Fusion Shox o2-R rear shock on my marin alpine trail. When the bike is ridden there is a squelching sound comingfrom the shock. Is this a leak or is this the norm.
Also if I was to consider upgrading the shock what would be your preference? I will try to go with something which is light and has a lock out facility.

Squelching is probably normal (just oil moving around the compression and rebound cicuits).

Change of shock depends on budget, but my preference would be a Fox RP23. No lock-out but it does have pro-pedal which reduces bobbing whilst keeping the shock active (excellent for XC and trail centre riding).

Many thanks. How is the rear shock measured, If i remove my existing and measure the distance between the eyelets it this fine?

Need distance between eyelets at full stroke and stoke length. So it will be something like 190mm long x 50mm stroke.

You also need to think about mounting hardware. Some use an eyelet diameter of 1/2" (12.7mm) (e.g. Fox and old RS) and some use metric 12mm (e.g. Manitou and new RS). So if your existing shock uses the same eyelet dimensions your existing mounting hardware will be fine, otherwise you will need new hardware too.

P.S you've duplicated this question in "General" - you should delete that one.
