I have a mountain which is great, It was a Felt Q720 which I've upgraded with a Shimano M770 Hollowtech II bb and chainset + 540 SPD, Avid Juicy 7 brakes with 203mm (8") rotors on front/rear and RockShox Revelation 426 Dual Air forks + PopLoc, I currently do about 18 mile round trip from where I live and I try to get out as many times as I can, this can be upto 5 times a week.

Over the Christmas holidays I took my bike to France while I stayed at my parents house. Some good riding though the weather was a bit hit and miss, which was a shame as my parent house has 200 sq/km forest right on it's door.
