Thinking about a new chainset - the existing Shimano 105 (5505) on the Galaxy is getting battered and the rings have seen better days, too. What's the panel's opinion on Hollowtech II? The bottom bracket looks vulnerable to environmental crud, and non-cartridge system seems retrograde... I'm looking for good, smooth shifting (9 speed) using sram chain. And what series to replace it with 105? Ultegra?
Cheers in advance
Tim

They are cartridge bearings AFAIK, just in two halves. Technically it's a better solution because of the wider-spaced bearings, although it's always disappointing to see new incompatible "standards" appear on what should be a fairly well-developed piece of technology by now.
The original Octalink BB (big axle, normal cartridge inside the BB shell) holds up well in my experience - I'm a serial destroyer of UN- series BBs - but the cranks have a tendency to loosen because the splines don't have a taper built in.

Sigh... all things being equal (same seals, same loadrating for the bearings, same precision on alignment) it would have been..

My HTIIs are doing brilliantly and are rarely cleaned of the mud and stream crossings I do with them. You can genuinely feel the increased stiffness over a normal similar-price crankset and the shifting is great, though I hear the rings wear quite rapidly - though there are as many people claiming thats rubbish as there are claiming it. I've been pleased with mine overall, and its a very noticable weight saving on my setup. Its a piece of cake to take them on and off if required. I didnt get my frame faced as recommended.

Cheers guys... that was interesting. Food for thought.
