Help with servicing my Rolf Sestriere Hubs(4 posts)

Help with servicing my Rolf Sestriere Hubsspincircles

The hubs were made by DT Hugi I believe. Here's the deal, they saw some nasty weather last year and the front hub is no longer smooth. It has that gritty feel. I've gotta say my chorus hubs on my training wheels have seen 10x the rain, snow, salt, and mud, still running flawlessly. Anyway, I do my own wrenching, but have only ever had to service threaded axle hubs. So I'm looking at my endcapped Sestriere hubs and I'm not quite sure how to crack this nut. The manual is no help, it just tells me to bring them to an authorized dealer for service. Anyone have advice on how to overhaul these things at home? Thanks,
Um, don't?TJeanloz

The Sestriere (DT/Hugi) hub uses a sealed bearing design which was built to be replaced, rather than overhauled. If I recall correctly, one of the endcaps screws off, which will make the other fall off - but that will only get you to the cartridge bearings, which you really can't do anything about besides replace.

most likely, the gritty feel is just dome dirt in the exterior rubber shield. This is a rubber shield under the end cap (that you see) but on top of the cartridge bearing.

Use an axle clamp or pair of pliers+rag to simply pull the end caps off. You will see. This is a very nice, well sealed design. Even if the bearings ARE a bit crunchy, you can still regrease them. As in most all cartridge bearings with rubber seals, you can carefully pry off the rubber seal with a needle, knife or whatever and clean/repack with grease.

yeah, i had the same problem, so out come the robogrips and off come the end caps, then whack the axle with a dead blow to push the bearings out, then get the new ones from the local bike shop, press them in, and presto, new feeling front wheel
