looks to have a manitou axel fork, X fusion shocks and smattering of shimano parts. It has a FSR suspension design and disk tabs front and rear so it would probably make a great beginner bike and the price is really good. Providing the frame is solid and not cracked anywhere you could easily ride that competently until you decided to upgrade then you could pass it on to a friend to help them get the bug.
Shimano doesn't make bikes, they make parts for bikes.The add said Shimano FSL bike.
http://www.hmbike.com/I looked up the HM and couldn't find anything I even ran the Serial number with no luck.
Possibly, if it's in good condition, if it's the right size frame for you and it's suited to the type of riding you want to do.Would it be a good entry bike and would it be worth 100-130 bucks?
