Rockshock Recon 351 spring change?

xgeek

Hi Guys,

Had my GT XCR for almost a month now and I think I need to get the spring changed on my Recon 351 U-Turn . I am not sure what spring comes as standard but I have a lot of sag. I.E. if I set the fork to 130mm and sit on my bike it compresses the forks well past the 85mm mark. :oops:

I currently weigh 109kg (down from 135kg in July!) and my target is 90ish kg. I found the below on the net and it looks like I need a black spring.

I live in North London (Enfield) and was wondering if anyone knew anywhere I could take it locally to get the spring changed? I guess it needs to be done in a LBS rather then me changing it out?

Many thanks in advance for any suggestions.

The official ratings from RockShox are as follows:
<140 lb. (63 kg) Yellow spring
140-160 lb. (63-70 kg) Red spring
160-180 lb. (70-80 kg) Blue spring: Firm
180 lb. (80 kg) Black spring: Extra firm

hey i would say get the spring and try it yourself. its a matter of two bolts as the spring should come as a whole assembeley. you just need to undo the top cap on the fork and drain the oil out, under the bolt at the bottom of the fork leg and the spring will come out. then put the new 1 in using nice new oil.
job done!!

Many thanks for the info.

New to biking so a bit scared of messing up. Do you know of any guides on how to do it?. I guess the spring is in the U-turn side but not sure if the spring can come out without messing with the lockout/motion control side?


Cheers

After doing some more digging I found this guide on TFTuned.
Seems pretty straight forward (famous last words!) so I will order the spring and give it a go.

Correct. But in the Sram service manual it says I have to remove the lowers first but images show the lowers still on :?. The Sram web-site seems a bit of a pain to find info so thought best to try and get a 2nd opinion

You don't need to remove the lowers, but you do need a hex socket for undoing the top jobbie. A 12point one will most likely round off the nut rather than turning it, oh and do it at full extension and don't put any part of yourself above the spring just in case!

Okay changed the spring over to an extra firm (black) and the forks are much better.

In the end I did remove the lowers as I wanted to see how to service the bushes, plus I wanted clean out and change the shock oil in the lowers.

Now I do have one issue and that is my u-turn is now stiff to turn. I got a pot of grease from TFtune when I got my spring and I made sure I lubed the spring up as well as the nylon part that screws up and down the spring at the bottom to adjust the height. I have also read the FAQ and checked the top bearings are clean and greased as per this post but it is still stiff.

I am not expecting to have to change the height much but nonetheless it is a bit of a pain. I think the spring is clamping on to the nylon part and causing too much resistance when I try and adjust it.

I am hoping it will loosen up after a few rides but if not I will wait until I have to service it again
