Lyric coil - possible to reduce travel from 170 to 160mm?

[AndrewQ]

Does anyone know what parts are required to reduce travel from 170mm to 160mm on a 2011 RS Lyric (coil) ? RS sells both, but I can get the 170mm for significantly less money but my bike frame is spec'd for the 160mm axle to crown height.

I searched the forum and only found info about the air sprung lyrics.

I don't see a fixed travel 160mm option available. You could purchase a U-turn spring assembly & top cap.

Can Fixed Coil 170 Lyrik Be Reduced to 160mm?

if only these forums had some way to search...

10mm axle crown isn't that much either. I'd give it a try before shortening.

I agree 10mm isn't that much but that link was almost useless. Shortening the spring rod (done properly) isn't the easiest option for a home wrench. Just slapping in a spacer preloads the coil by the amount of the spacer height.

Thanks for the link, I didn't see that in my previous search. Some of those ideas weren't very good (like the ones resulting in excessive preload), but cutting that shaft down by 10mm and re-threading isn't too tough.

Pretty sure the end of the spring rod is stepped. I contemplated shortening the rod on another RS fork but done properly would require a lathe - not working w/ much material in that area.

Agreed, but it should be pretty simple on a lathe (I have access to a machine shop). I'll either go that route or just buy a u-turn coil assembly.
