No more bobbimg
I bought this fork to replace a suspension fork on an older Specialized mtn bike that i converted to a rail trail bike. I didnt need suspension on the rail trails, and found iI was losing foward momentum because of all the bobbing when I was pedaling hard or standing up. The rigidity of the Surly fork made riding this bike on rail trails or around town made the ride more efficient. As a larger rider, I appreciate the oversized tubes as well to support my weight.

PROS: Durable, Easy To Install

BEST USES: Casual Riding, Mountain Biking

Rediculously fast shipping!
I bought this fork to replace a suspension fork on my Norco Torrent frame. I'm building up a polo bike. I put the fork on as soon as it arrived, 20hrs after placing the order. Can not believe how fast it got to my house in Canada. No shipping damage. After my first test ride I am very pleased with my purchase.

PROS: Super Fast Shipping, Good price, And no duty charges, Good Quality

I really love the...
I really love the feel of these forks. I use my bike as a commuter weekdays 5-6miles one way for work, and Trails on Weekends. These forks make my bike roll so much faster than when I had suspensions on them. I have so much energy left in the tank I always find myself trying to find a longer route home.I have fallen in love with riding all over again. I also bought a pair of Cane Creek Ergo II grips. The combination between the forks and the grips are extremely comfortable.I really wanted to by another bike for commuting and comfort, but couldn't really afford a quality bike right now. Just by replacing the forks to rigid, I now have a true all terrain bike.

Will this work to replace a 100 mm travel Suntour XCT 27.5 disc fork. The A-C seems the right length.
If yes, what adapter should I get?

Will this really fit a 26' wheel or can it hold a 29' wheel? I'm looking for something that will only hold a 26' wheel. Thank you!

BEST ANSWER: this fork holds a 26' wheel perfectly. the biggest concern when buying a rigid fork is getting a fork with the closest axel to crown length of your current bike.
