    First service: what to look for

    Hi all,

    In the next month or so, I'll be taking my quite new (Mar 2011) Helius AC into the LBS for a couple of tweaks I don't have the tools or expertise for.

    While I'm there, I thought I'd ask them to have a look at X.

    Now I can't remember what X was. I remember reading about it months ago and it was something fairly specific that Nicolais in particular (compared with other brands) should have checked soon after purchase. Something to do with the bottom bracket perhaps? Or bearings or bushings?

    I checked the Nicolai manuals page. It's in German, which is fine. I can read it OK and my LBS is German-speaking (and they built the bike), so I can point them to any relevant document. But there's no Helius AC section and, more importantly, nothing is reminding what X is.

    Thanks!

    Bearing preload.

    Nicolais must be checked for bearing preload after some use.

    Also, check for any bearing/bushing wear, just for kicks.

    I like to fix my bike myself but Ive never had a FS before. I own a Helius AC 29er. How do I check the bearing preload? Are we talking the bearings where the rear triangle meets the frame near the bottom bracket or alle bearings on the frame?? Are you supposed to disassemble, assemble and tighten, or could I just tighten it a bit? And how do you know what kind of preload? Just so theres no play and it moves ok?

    Just wondering if anyone had an answer to Rockefoten's question on exactly how to do this?

    no play in the bearings and the rear triangle should need about 2-3kgs of pressure at the rear axle to break loose (obviously rear wheel + shock unmounted). I set up my Ion with about 3-4nm at the swingarm bearing and round about 2.5nm for the rest, that normally fits perfectly....

    Well, I couldn't find the info exactly in either language, so it's good it's out there for others to find now.
