I've been running a set of 2010 Rockshox Lyrik coil uturn forks on my Nomad for a few months now and have noticed that during the course of a ride the forks feel as if they are stiffening up. This feels at the time like a loss of 'plushness'.

The forks were serviced only about three weeks ago - new seals, oil and a mission control damper (under warranty). All geared up I'm about 205lbs and I'm running the stock spring. I'm sure the forks used to feel much better than they are at present. It possibly feels as if there's alot of stiction going on.

Any ideas anyone? They're ruining the overal feel of the bike.

I have a two step Lyrik so I can't comment on the coil versions. But could you put some more description into the loss of plushness? Is it slow speed or high speed, small hits, big hits, How quickly is the fork moving? Does if feel over dampened? How much low and high speed compression are you running? This may seem insulting but have you turned down all the compression and dampening settings just to see if t makes any difference? I know you have a RS Lyrik but these Fox videos are super helpful in set up. See if they have anything that can help you with the settings. If its not the settings they its a service issue.

Maybe they didn't put enough bath oil in and as it cycles and the oil splashes around, there isn't enough to keep the fork lubed up? I've read the dampers are very fussy as to how much oil is in them as well - perhaps not enough/too much oil in them?

Wilsonblur, Gticlay

Thanks for your thoughts.

Lately I have been running the forks with no LSC and no HSC dialled in and the problem still exists. Basically, the forks feels very over damped, but interestingly not when you first set off. It kinda kicks in after about 20mins or so and the travel seems to lock out at about 120mm (but it will fully compress if you put enough weight through it). Small bump sensitivity feels non-existent.

I've carried out the 'Pinkbike Floodgate removal' procedure but there's no noticable change.

Unless someone can suggest a quick fix there off to TF Tuned so that they can work their magic on them.

I have had a Lyrik coil U turn for about 3 years and have fought with this same problem. After tearing it apart, re-lubing/re-build, etc I've decided that the design just doesn't allow for enough oil in the lower legs. I think that the oil gets knocked down to the bottom during the course of riding and doesn't appropriately lube the stanchions. Try turning your bike upside down for about 10 minutes or so before a ride. it really allows the oil to coat the stanchions and makes for a smooth ride. Sometimes I even turn my bike upside down on the trail if I'm resting or waiting for a friend, etc. Seems to work for me, but it is annoying.

Do you pics, I want to see how you mounted a set of Rockshox Lyrik(s) on your bike?? Ive only ever been able to mount 1 fork to any of my bikes, never a set (2). :thumbsup:

Will get the pics to you soon. Bike feels great being run as a tricycle with two wheels up front

Glad to see you have a sense of humor, very refreshing.

I have a thought about your fork issue too, maybe they used the wrong weight oil in the rebuild (too heavy). RS forks are very sensitive when it comes to oil weight.
