Last year, Specialized had a “bike launch” at Woodward West, where a few of us Ride guys got to ride around on Specialized’s new completes.For us, the Fuse IV held up perfectly (even with a few nose-cases-to-over the bars). But, a few editors getting loose for a day is hardly a test, so we passed on the Fuse IV to our tester…

What did you like about the bike?

“Pretty much everything; there’s nothing really wrong with it. The only thing that’s weird is the bars. TKTKTKTKTKTK”

Did you have any problems (bending/breaking/repeated adjustments)?

“The pedal cracked all the way down the center, but I don’t know when it happened exactly. If I landed hard again it’d probably break…”

What kind of stuff did you ride with it?

“Street, park, and dirt-everything.”

Would you consider the Fuse to be a good value?

“Are you kidding? Yeah, it really is. This is has to be one of the best completes you can buy.”


Pros: “The small gear, the weight, and the geometry is excellent.”

Cons: “The weird bars.”
