Honestly, They have not been on the top tier of bikes in over 20 years. Not saying they are bad. Depends if you get the ones build for Dicks Sporting Goods or you find the bikes spec'd for the LBS. For $2500.00 you can find Trek, Specialized, Cannondale, Giants................
Mechanical failure isnt the issue. I test rode a few bikes before bought. Pedaling efficiency was the issue. Cheap bikes break you sooner.
I bought 2008 specialized enduro expert for $950. Having the front and rear suspension rebuilt was an unexpected $650 extra. That sucked and the pedaling efficiency of the enduro is prety terrible, but my suspension is like no other. Considering my list of past injuries, not having to stand up on most of the trails is a significant advantage for me.
I really like my buddy's 29er stump jumper fsr for efficiency but the ride on my bike is so plush that i have no complaints.
