K2 Sidewinder?

[Carbon_Angus]

the EVO frame main pivot location is on the down tube at about big ring level where the canti-swingarm attached.

yours seems to be at/behind/near the BB.

it looks like an inbred cousin to an old Trek

Good luck with finding out more about it. Let us know how it rides and handles, too.

Your right Carbon, the pivot is directly above the bottom bracket.  I am not sure about the old style single pivot suspension, is one pivot point better than another?

My friend has a sidewinder fram as well, and on another forum someone told him that there was a section of K2 that would make "custom" production runs for companies such as department stores that wanted their own bike but with the K2 brand name.  And the Sidewinder is one of those bikes.  I may be a bit off on the details but that's the gist of it.

Yes, go ride and give a report.

One upgrade that may really turn your sidewinder into a jewel could be a used Manitou Swinger, 5th element, or Fox stable platform shock.

Many companies have been abandoning proven swingarm geometry royalties in favor of lesser designs that are saved by infinataly adjustable stable platform air shocks. I got a new 7 7/8" i2i x 2 1/4" stroke Swinger for my Oz that gives me 6 inches travel on the rear for $99. Got it from a Santa Cruz Factory online inventory sale. I am sold on them.

I have gotten used air swingers for as little as $50.

Just a thought.
