Go with the OEM parts and have the LBS do the work. Find out the warranty on their repair. The factory parts will fit better. More expensive? Yes. Still cheaper than buying a bike to ride while you try to save money finding bearing and things. Writing a check is easier than "saving some money". I guess it's pay and pedal or save and rave. not necessarily sold on a real reason to get ceramic bearings over regular quality steel bearings for suspension (maybe wheels?). The ceramic bearings are designed for "high speed" and "high heat" applications. However, these are quality bearings, offer a double seal and cost the same as all other decent kits out there (including OEM). I think the bearings offered by Boca are better quality than what Specialized does for the same price.

Last weekend, I did the Triple Bypass, and got caught in the thunderstorms. When I removed my cranks (2010 Campy Record 11) to pack my bike, I saw that the grease in the crankbearings had turned a dark grey. Should I try to flush and repack these bearings?  And if so, how would I do that?  If that requires a bearing puller, which one should I get? Finally, these bearings aren’t sealed – is it worth considering sealed replacements?

As for the bearings, yes, it’s a good idea to re-pack those bearings. This is the tool to remove them. Here is how you remove the bearing shields, no matter what type of shield it is. Once the shield is off, you can do no further disassembly and then can do a relatively unsatisfactory job of cleaning the old grease out and packing in new grease; I say unsatisfactory, because the bearing retainer will be in the way of both operations. Here’s how you really clean a cartridge bearing, polish the ball bearings and the bearing surfaces, and repack the bearing with grease. This may seem laborious, but if you have ceramic bearings you’ve paid big bucks for, you may find it well worth your while.

I also find that changing my gear ratios and wheel sets with better ball bearings does more for me than dropping a kilo of weight or pedaling uphill with only one water bottle instead of two.Thanks for the direct answer to the fella who wrote to you about bicycle weight. I think it settles something that often gets asked of me. I’ll tell guys that a local climb that takes an hour-forty to summit I could potentially do in 90-something minutes. For the moment, I’m happy with my Corsa Extra and MX Leader by Merckx, and a Columbus SL number by Bottechia.
