    Soften an old fork

    I have one question. Older model forks like the RST 381R use elastomers/springs. Mine fells very stiff. If I take the elastomers/springs out from the ONE leg will it work? I was reading an old mtb magazine saying that somebody took off the spring and oil from a marzocchi fork, instead of putting softer spring and it worked great. What do you think?

    I think

    you'll get a better answer over in the "what fork to get" forum. Jim

    I agree with Jim. Tuning a fork is an adventure even for hobby mechanics. Getting replacement parts for older forks is often difficult. So the standard answer is: buy a new one.

    If you like wrenching: Don't expect fast results and get going. It is fun to see how a fork works.

    I think that would be a bad idea.

    Since those older forks were designed to have springs in each leg, removing one side would make that side compress much much easier than the other. This might make that un-sprung side compress on small bumps while the other side didn't. You could end up with a wheel that tilted sideways on each bump and the force that used to be absorbed by the second spring would be transmitted to the sprung side via the brake arch. Because that arch was never designed for that extra force it could end up snapping.

    I'd be more worried about the axle. Way back when I saw a number of broken axles due to blown seals in oil damped forks. Forks sure have come a long way from bolt-on arches and hubs that where basically designed for road bikes.

    Re softening the old fork... sorry but I think that one is done. Elastomers wear out, and if the manufacturer isn't supporting them anymore, you are pretty much SOL, unless of course you can work out some way to use currently available parts in there. Even NOS elsatomers might not work as they do degrade over time.
