The group-think that can plague mountain bike culture led me to the new X-Fusion 29er fork. Many riders think you have to ride a 29er; you have to be on Strava. And of course, you absolutely must ride a RockFoxZocchi. (SCROLL TO BOTTOM FOR AN UPDATE)
Which is ridiculous. There are great alternatives out there, and I’ve uncovered one of the best deals in mountain bike forks in the X-Fusion Shox Slide 29 RL2.
Why Be Different?
So, why not skip the X-fusion 29er fork and just get a Fox? Fox makes great mountain bike forks. I’ve ridden a Fox Float R for six years and had it rebuilt once.
Well, the cheapest Fox fork I could find was $600 – more than I wanted to lay out for building my Raleigh XXIX frame into a belt-drive singlespeed mountain bike. You can pick up an X-Fusion 29er fork for about $400 – a great deal for a mountain bike fork. That’s enough extra clams to get a GoPro Helmet Hero so you can make bad mountain bike videos.
Setting Up the X-fusion 29er
I have a good home shop. But no headset press. I turned to a local shop for installation. Good thing, too – the tapered steerer tube combined awkwardly with the Cane Creek headset I planned to use. There was friction while turning the handlebar, and we couldn’t adjust it out. The shop staff put in a Chris King NoThreadSet as an experiment. The result? No friction. A bigger hit in the wallet. But I at least wound up with a cool gold headset.
I guessed at air pressure based on the manual’s 50-150 PSI range. I put it at 100, figuring it might be slightly soft. Did I do the whole bike geek “put a zip tie on the stanchion tube and get on the bike and see if it sags 20 percent into its travel”? Hell, no. The bike stand isn’t real life. Make an educated guess. Take your mountain bike for a ride. Bring a shock pump. Fork blows through its travel? Add some air. You bounce around like a Ping-Pong ball on ice? Let some air out. Done.
On my first ride aboard the newly built Raleigh XXIX, I had questions. Do I have the Gates Carbon Drive Dialed in? Did I install the Stan’s tubeless conversion right? And will this crazy X-Fusion 29er fork detonate into a thousand pieces?
Eight rides in, I’m alive. Looking forward to my next ride. Happy that I didn’t shell out 30 percent more moolah for … a difference in performance that’s indistinguishable from my Fox FLOAT R. The 100 pounds of air pressure was on the money. I backed off a click on the rebound damping, and the fork was dialed.
Oil marks on the stanchion tubes tell me I’m getting a lot of the X-Fusion Slide 29 RL’s 100mm of travel (it also comes in 80- and 120-mm). But no harsh bottoming. No wiggly steering performance. What’s not to like?
Niggles and Nitpicks
The Slide 29 emits a conspicuous hiss when I smack it into a square-edged obstacle. It reminds me a bit of air-sprung shocks of an earlier era that were notorious for the hiss (Old-timers will remember “Amp-physema”). But my air pressure checks show no noticeable drop in air pressure. So the air is staying put.
Also, the Slide 29 stanchion tubes attract gunk more than my Fox Float R. That might mean seals with a sloppier tolerance. Or I could be a fork hypochondriac.
The decals will look thrashed in a few months. I’ll probably wind up peeling them off, rubbing the residue off and winding up with a Spinal Tap “how much more black could it be?” look.
Where Do They Go Now?
After just short of two months, I like my X-Fusion 29er fork a lot. I hope I still like it as much after six months – if I do, I’ll say “Buy without Reservations”. It looks good now, but time will tell. Right now, I ride my Raleigh XXIX and come home happy. That’s what it’s all about.
The hard part is in X-Fusion’s court. It has to make a case with bike manufacturers’ product manager to get spec’d on bikes. They need to make a performance case and a business case. With the brand loyalty and economic power of Fox, Rock Shox et al, that could be difficult.
X-FUSION 29er UPDATE NOV. 9, 2013
A problem cropped up with my X-Fusion Slide 29 RL2. Here’s what I sent to X-Fusion:
Hi there. I’ve been riding a Slide 29 RL2 since February. It’s been a great fork, but I have a problem and wanted to see what you’d recommend.
