Title: Clydesdale 856 Rear Shock Feedback Please
Post by: Neffro on February 15, 2012, 06:38:11 pm
When choosing between Noleen and Risse for a rear shock replacement on a ProFlex 856 for a 250 lb rider, what is my best choice?

My current set up is a firm Speed Spring, but my ODS has a oil seal problem.

Any feedback from others 856 riding Clydesdale's is appreciated.

Thanks

Scott

You can't go wrong with either. I like airshocks, so I like the Risse airshocks, but they do have a bit of sticktion.

The Noleens are really smooth but not as tunable.

Either way is a winner.

The ODS is rebuildable as long as the shaft is not scored.

I think it depends on whether you prefer air springs or coil springs. I prefer coil springs, so I got a Noleen NR-4. Having two-way-adjustable damping is awfully nice, as is having a spring that doesn't behave differently in different weather.

............... as is having a spring that doesn't behave differently in different weather.
surely the elasticity of the steel varies dependant upon temperature?    <SMILE>

Within a range of 50C? The properties of a steel spring won't change nearly enough to matter, and the same is true if you're lucky enough to score a titanium spring. The properties of air and/or rubber elastomers change far more between those temperatures. Perhaps if you live somewhere where the climate is fairly constant it's a minor concern, but where I live it can be 35C one day and 20C the next day. Having to adjust my shock every time I go for a ride would be very irritating.
