Anyone know where I could buy replacement bearings for these hubs online?
Are they standard bearings? If yes, any idea about size?
Nevermind, sorted now.
Have a look at them? You'll need to take them apart to replace them.
6902 in the main I think (on a 240 anyway).
Yes, thanks njee20. They're 6902 like in the 240. I didn't have the wheels right in front of me to check and needed to order spares in a hurry. The bearing size is actually stated right there in the official manual, but I blame my caffeine deficit this morning for missing it 😳
Easily done. I have a vague recollection they're different in the freehub body if you're doing those.
When I rode the bike last weekend the front was very rough. Should be a straightforward job as the exploded diagram shows that the axle caps and dust covers just pop off easily without special tools. I think I might just service the rear as well since I bought the wheels second hand and the rear bearings might be on their way out soon, too. That said, if the rear has the DT Star Ratchet I think I remember reading somewhere this needs a special tool to remove/refit. I'll have to take a closer look at all of this tonight.
