Thinking about getting a coil shock for my Blur 4x, keep the air for longer XC and swap out to the coil for playing on the downs.
The shock length (i think) is 200mm x 50mm
The 200mm is eye to eye fitting, and the 50mm is the stroke length, right? So I have to get a 200 to make sure it fits the frame, but i've seen quite a few 57mm stroke shocks, presumably these will fit, but potentially give me more travel, with the possibility of the frame smashing into the rear triangle?
Has anyone got a coil shock on their Blur 4X?
Does anyone have any recomendations? Thinking something fairly basic like a Van RC.
Then the coil "weight", does it make a massive difference? is this just for tuning it to your weight?
oh yeah, the bushings, can i swap the bushings form my air shock onto the new coil shock, or will i have to budget for new bushings as well?
thanks
There's a few people on the MTBR forums who swear by both the coil and the 200x57 shock - the longer stroke ups you to about 125mm travel, if I remember right. I'm told it won't hit the frame, but I'd be careful about checking it first.
Have a browse here

Saw the mtbr thread, and the fella on there was talking about adding a bit of oil to reduce the stroke length. that kind of fettling is beyond me, shocks are left well alone!
Not sure how to check without getting hold of one first? and would an extra 10mm of travel even be noticable?
Buy a coil shock. Get the correct spring for your weight because yes it does make a difference. Springs come in different lengths as well. I use a 750lb x 2.30 fox and Im 17stone and like it a bit firmer. Theres a spring calculator on mojos site,I believe. Bushings from a fox aircan should fit a fox coil - I moved some from an rp23 to a vanilla the other night with no bother. Fit it to the bike and it shouldnt hit the frame as long as the i2i distance is the same. Tweak it,get it feeling right then forget about it.

Beyond me too - but there are more than a few people who've done it. The tyre would bottom out on the frame rather than the snock hitting it, but apparently it's fine.
There's no way to check other than fitting a shock with no coil on it, and cycling the bike through the travel - can you borrow a suitably sized shock before you buy?
I replaced a Fox DHX 4.0 Air with a rather more basic Vanilla R on a 2010 Giant Reign. The bike rides better and I don't notice the extra weight, about 400g. My shock had a 57mm stroke and the bike should have a 50mm stroke shock. I got my mate to make me a 7mm nylon spacer that fitted onto the shock shaft to reduce the stroke. Been riding it for a few months now with no problems at all...

A 200x57 will fit, I ran one on mine for a bit. IIRC it takes the travel up to just over 130mm.
Didn't cause any contact issues.
thanks hobnob, what shock did you run?
Was it any good?
I didn't do it for long to be fair as I stole it off my wife's bike.
It was a Push'd RP23. It rode really well to be fair, never felt the need to put a coil shock on it, as it would make a reasonably weighty frame a bit of a porker.
thanks,
yeah, its not light!
Was thinking on keeping the air (RP3) for longer XC days and getting a coil for more downhill stuff. With a 130mm coil, coil pikes and some dh tyres and tubes, i'm hoping it'll be perfect for the passporte du soleil and a little bit of downhill in the alps.
sounds a great idea, id be tempted to run some 160m plus forks for dh stuff though, just cos its fun!
