I have to admit that I'm a bit skeptical. Why do you think the Surly 1x1 fork will be perfect?

The reason I ask is because the specs for your bike claim that it has 100mm of front suspension travel. The Surly 1x1 fork seems to have an axle to crown race measurement of 413mm. I put a fork of similar length on a bike that was designed for a 100mm suspension fork and it completely ruined the handling! The bike was so twitchy I could barely ride it on the street, let alone off-road.

I've been riding for a long time, but the handling of the bike was so bad I ended up throwing the fork in the trash and replacing it with a Surly Instigator fork. The Instigator had an axle to crown race measurement of 447mm which is obviously what the frame was designed for; it rides like a dream now.
