On holiday with Mrs B and the B-ettes last summer I slipped my lease on a couple of mornings to go on two guided mountain-bike rides. I had never been on a mountain bike before, but I had about the best fun with my clothes on I've had for years. I thought it was the location (Greece), holiday spirit etc, but it's now several months since our return and the yearning to ride an MTB again has not left me! What bike should I buy (the holiday ones were Gary Fisher)? I wouldn't get out on it too often, I already own 4 bikes so a 5th may proove domestically (both politically and in terms of storage!) tricky, I live in Birmingham (not noted for it's off road riding unless you know different), I just want something I could occasionally have a bit of a blast on, I'd prefer to have your thoughts rather than stipulate a budget. Any sensible suggestions will be gratefully received. I have read the What MTB thread and to be honest got a bit confused.
