Hi, I'm building up a specialized stumpjumper fsr120 frame (I think it's a 2006 model). Does anyone know the rear shock dimensions or have any suggestions about which would suit this frame best? I believe they originally came with a fox shock but I'm not sure what to go for now. It''s a budget build so I'm scouring eBay for a bargain!!!

    Looked at the file in the FAQs? If it was a fox it will be on it.

    Cheers, I found the details in the FAQs. It states 7.5" eye to eye and 1.75" stroke. Do I have to get exactly the same size or is there a bit of leeway when it comes to replacing it? Obviously if I put a massively different shock on it will throw the geometry out but would 10mm here or there make that much difference?

    needs to be the same or you will lose travel.

    Having a quick look around the web 7.5" x 2.0" (190mm x 50mm) seems to be the standard size. Apparently the 7.5" x 1.75" that specialized used on the '05 stumpjumper was a custom jobby.
    Does anyone know where I can get one from or if the 2" stroke version can be adapted?

    Call TFTuned, they'll sort you out. Probably Mojo too.

    ry - this info used to be on the specialized website under 'archive' but it looks like they've recently ditched being helpful.

    The fox septunes these bikes were fitted with almost never come up secondhand so, as Yeehaa says, best speak to Mojo or TF about customising a standard shock.
