Date Reviewed: May 12, 2008

Strengths:    Cheap, very strong, v-brake/disc compatible

Weaknesses:    Heavy, shudders in heavy braking

Bottom Line:   
This fork is perfect for riders > 200lbs. as it is pretty strong. However, I find that it shudders under heavy braking on descents but maybe I'm the only one? I'm running 185 discs. I paid only $35 so I shouldn't complain too much.

Date Reviewed: March 14, 2007

Strengths:    Solid rigid steel fork that complements the Karate Monkey frame quite well. Can be run with V brakes or disc brakes. Holds line like a champ. Price is affordable.

Weaknesses:    Heavy and probably best suited for the heavier/larger rider.

Bottom Line:   
It is hard to beat the price since the fork came with my KM frame. I like the stiffness of the fork and it performs well on most Iowa singletrack. One needs to gain some suspension with a front tire that provides some cush. One could add a carbon handlebar and comfy grips so the fork will be less harsh, but this is a steel rigid banger. It's nice to have a maintenance free fork. One less thing to worry about.

A Karate Monkey frame and fork can be built up light. My size XL with gears coming in at 23.9 pounds does not feel like a heavy bike underneath me at all. It flat out flies on the trail and for where I ride, the fork rails the corners and allows me to hammer ride out of the turn with no flex.

Lots of chilis for value.

Submitted by Ivan a from Red Republic

Date Reviewed: December 21, 2006

Strengths:    Cheap - especially since it came with my monkey frame. Stiff (which is both good and bad). Looks fine.

Weaknesses:    No disc only version. yeah it goes against KM spirit of changeability - but my canti-bosses are rusting from the inside out.
Stiff - damn thing rattles out my teeth on baby-head downhills. For everything else - works well


Bottom Line:   
For the price (free with your frameset) or on sale - this is a bargain fork. If you're wanting a more forgiving rigid ride you may want a Ti fork. Perhaps talk to Walt. But for cheapie - this is it.

Submitted by Martijn a Cross Country Rider from Holland

Date Reviewed: December 4, 2006

Strengths:    Cheap, stiff and clean looking

Weaknesses:    Stiff as in harsh on bumps, not that light, not enough rake

Bottom Line:   
Nice fork for smooth trails but a bit harsh on bumps.
Tree roots, stones and trail bumps make it a bumpy ride with this fork mounted.
Next fork will be a carbon one with a bit more rake and a bit more give.
For commuting it might be the ultimate fork, cheap and stiff.

Submitted by GlowBoy a Cross Country Rider from Portland OR

Date Reviewed: December 1, 2006

Strengths:    Cheap. Stiff. Looks good. Extra rake may quicken the handling slightly and helps prevent toe overlap.

Weaknesses:    Stiff. Harsh ride for 165 lb riders like myself.

Bottom Line:   
Cheap rigid fork that gets the job done. Others say it's fairly compliant under 200+ pound riders, but for smaller guys it's downright brutal. I went from a lightweight rigid 26" bike to the 29" Karate Monkey (frame and fork), and the ride actually got harsher.
