Well, I don't know. I'm looking to replace the whole front of my drivetrain ("singlespeed").

I need a chainring around 30-38T and I'm looking for weather resistance, so I guess I'll need a sealed bottom bracket. Durability (in terms of impact resistance and wear...and I'm not talking about pedaling around the skate park, but thousands of miles) are a priority as is a full bashguard.

Price might not be that much of an issue if it weren't for the fact that I really don't want to waste money on something I won't be happy with.

Can you recommend anything?
