Vintage 2001 Klein Attitude Mountain Bike Made in the USA – Large (Made by Trek)

Industry Description:

The 2001 Klein Attitude, bearing the “Made in the USA” stamp, represents a fascinating intersection of mountain bike history and brand ownership. At this point, Klein had been acquired by Trek, but the distinct design language and reputation for lightweight, responsive aluminum frames persisted. The Attitude, in its 2001 iteration, likely showcased Klein’s signature features, possibly including their Gradient tubing and unique frame geometry aimed at maximizing rider input. While Trek’s influence may have been present in component choices and manufacturing processes, the core DNA of the Klein brand, known for its performance-oriented hardtails, was still a key selling point. This era represents a transition, as Trek integrated Klein’s technology and design into their own offerings in later years, making these “Made in the USA” Kleins, particularly the Attitude, highly sought after by collectors and enthusiasts who appreciate the blend of Klein’s innovation and the quality associated with that era of American bicycle manufacturing.

A little about the seller: I’ve been in the cycling industry for more than 30 years (I know, that makes me old!). I’ve been a professional bicycle mechanic for most of those years, including working locally at Lee’s Cyclery before they became Trek Stores. Now I work from home as a Customer Success Manager for a software team. But I still love fixing up and working on bikes, and riding them too! Purchase from me with peace of mind. Not only can you trust my years of experience, but I will also fit you for the bike and provide any mechanical insight at the time of purchase. No warranties or refunds are provided. The bikes are sold as-is. But It includes follow-up minor adjustments and fitting if needed within the first 30 days if sold locally.

Shipping information: I ship UPS Ground and the bike is disassembled. I do have a video to help in putting back together. Usually, it’s the Bars, Front Wheel, Pedals, and Seatpost that need to be put back on. I try to keep it simple. It will be packed very well, but if you see any damage to the box or bike keep the box and packing material plus, take pictures. I do insure all bikes that are shipped and require a signature. In addition, if shipped out of Colorado, there is no Sales Tax. Colorado customers, try to buy Local. Info below:
