Hi, A have a 2004 Scott Mountain bike, which despite its age is a decent bit of kit.

However the rear shock has gone, it is a DNM MM-22AR - I estimate it has 17cm travel and the spring is rated for 550lbs/in

I can't find a UK distribitor for DNM, and the product code I have seems non existant. How do I replace it ?

Thanks all

you wont find that shock for sale as its so old it will have been updated with a better model. your best bet is to try someone like tf tuned who are a shock service company but may have something in a box out the back?...

I assume though that someone somewhere makes another shock with the same dimensions ?

It definitely doesn't have 17cm travel!

You need to know the eye to eye length, and the stroke.

Eye to eye is measure from centre of one mounting hole to the other, with shock uncompressed.

Stroke is the amount of travel, with spring removed you can bottom out the shock and measure again - subtracting this from the free length will give you the stroke.

You mention 17cm though, what exactly have you measured to get this? What model is the bike? Reason I ask is I may by complete coincidence have a fox vanilla r up sale this week thst may fit!?

Sorry the 17cm is eye to eye. The bike is a Scott SX3 from around 2004.

How sure are you of that? As 165mm is a very standard size, never ever seen any thsts 170mm.

165x38 mm Is what I'd put my money on, (6.5x1.5 i'n imperial) very common older size. As mentioned above - I have a Fox Vanilla R going cheap that would fit - of your interested PM me as I'll get told off for peddling wares on here!

As you can see from the link they make a 170mm.. I have emailed DNM to see if they have a uk stockist. That is the correct shock but it doesn't have quite the same fitting on it.

Thanks for the offer on the Fox, but I am not sure that is the right item.

Have now removed the shock completely and we take it to a couple of places this week and see if anyone has a better catalogue

thanks

If you have the money to upgrade it is a perfect opportunity. You can transform your bike very easily with a new shock.

I think I'd risk loosing 2mm of stroke and 5mm of eye to eye if it meant running a better shock than that.

Indeed, the Fox is streets ahead of your present one.

Well indeed that was really my question. If I were replacing it and accepting that I can't get a like for like replacement, what should I replace with ?

The bike isn't state of the art, so lets not put a new bit on that is worth more than the rest of the bike. I use the bike for rough trails and easy (but lumpy) downhills.
