Thanks for the replies guys. All this stuff is new to me - but definitally something I'm interested in. I've been browsing the forums for a bit now and I see some people saying things that a MTB would be uncomfortable to ride on a street.

Can you tell me the main differences between a MTB and a Hybrid?

Like I said, I'd like to use it for commuting but also leave myself open to trying some trails. I think there is a single track near here too.

Thanks a lot,
