Rosborn mentioned the Acera groupo on the Kona could be a weak spot. If/when it bit the dust I'd like to know what it should be replaced with. I'm not going to fix what ain't broke (bad grammar hurt me but to say that any other way is just wrong!).
Exactly. My 18 year old son 6' 3" and 205 pounds, blew out two Acera drivetrains. We finally had the last one replaced with a Deore drivetrain and haven't had a problem since. I can guarentee that he didn't put as much torque on the drivetrain as you will be. My mountain bike has a Deore drive train. I rode with him and witnessed how he rode his bike. Acera components are garbage components for adults. They may work fine for teenage kids but they just aren't durable enough for stronger riders - hence the fact that Acera are put on low end mountain bikes that are geared for the entry level rider. The fact that Shimano doesn't even have this groupo on their website should speak volumes.
