X-Fusion 29er Fork – Slide 29 Gear Review -UPDATED

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.

Let’s Ride!

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. 

Here’s the situation: I did some work on my brakes yesterday, and had to remove the caliper from the threaded mount on the fork. The problem occurred when I re-installed the caliper. As I was tightening one of the bolts, I felt it something give and I could tell that somehow the threads had stripped. I removed the bolt and sure enough had some metal come out. Before I started tightening, I had the bolt lined up properly and there was no unusual resistance that would indicate cross-threading. 
If this info helps, I was using an old set of Hayes 9 hydraulic discs. I’ve also attached some photos. Do you have any advice that can get this fork back on the trail?
X-Fusion replied with advice to use a longer bolt on the affected mount. That’s a workable solution since only a few millimeters of thread are damaged. If more of the threads were trashed, we’d be in real trouble. The mounts are molded into the fork’s lowers, unlike the mounts on my Rock Shox fork (its mounts bolt to the lowers). So if this problem gets worse, I’m looking at a new set of lowers. Not really ideal. My guess is that the molded lowers let X-Fusion keep the price a bit lower. But it might be worth a few extra clams to have removable mounts.
Oh, and X-Fusion responded to my question within hours. I deducted points for the molded-in mounts on the Slide 29 RL2 (a factor I hadn’t considered before). But the company earned points back for being responsive.

Raleigh XXIX, Belt Drive, X-Fusion – A Few Thoughts

Raleigh XXIX, singlespeed, belt drive, McDowell Mountain Regional Park
An awesome new bike, my favorite local trails … what’s not to love?

Something about this bike that makes me a happy, friendly rider. I realize it as I greet a mountain biker headed the opposite way. Every time I ride this thing, I get so chipper that I’d say "hello" to a rattlesnake.

It’s more than "New Bike Syndrome." I’ve had plenty of new mountain bikes, and there’s something different here.

Maybe it’s the Gates Carbon Drive; I’ve wanted to try one for years. I salivated when I first saw the Raleigh XXIX with its belt drive. And hey! Wouldn’t you know it? That’s pretty much what I’m riding. I found a Raleigh XXIX stripped of all its parts at a local shop. They also had its belt drive bits lying about; I took those home, too (and ordered a new fork – more on that later).

Seven rides into life as a belt-drive singlespeeder, and I’ve had no problems. Haven’t touched a shop rag or a bottle of lube. Every bit of power I put to the pedals goes to the rear wheel. In just more than a month, I see a difference in my abilities.

And that belt drive. Many a mountain biker scoffs about it: "Is it really that hard to maintain a chain?" No. It’s not. But any extra work is a barrier – a barrier that can make it easier to say "You know, I’m tired and don’t feel like getting my bike ready. I’ll ride tomorrow." Maybe that never happens to you. But it does to me. And the belt drive is, as Forrest Gump says, one less thing. It’s also light and reliable, though the rider bears some responsibility for dialing it in right. By the way, you don’t have to be a mountain biker to ride a belt drive – they’re popular with the commuting crowd, too.

Hmm, what else about this bike makes me such a cheery nutjob? The X-Fusion Slide 29 RL2 suspension fork. I love the Fox FLOAT on my Santa Cruz Superlight. But those things are expensive! For about $400, the Slide 29 does everything my FLOAT does. And even something it can’t – it locks out.

On the trail, the Slide 29 works hard. Square-edged hits make it hiss a bit. But it steers where I point it. It makes short work of stuff in the trail. It didn’t cost me an arm and a leg.

A close look at one of the X-factors of my Raleigh XXIX – the X-Fusion Slide 29 RL2.

So we have a steel hardtail belt drive with a cool fork. Oh, and it’s a 29er, a novelty for me. If you’re a 26er holdout and expect me to say the Raleigh XXIX handles like a porker, sorry. It just doesn’t. And it rips through fast corners. The combination of hardtail and singlespeed pairs well with the 29er wheel; the big wheels softer the ride and preserve your precious momentum. I’m still not convinced 29er wheels are a must for every mountain bike (or mountain biker), though.

Speaking of wheels, I ordered some WTB Frequency i23 rims built on SRAM 9.0 hubs and added a Stan’s tubeless conversion. The wheels seem durable, but the Stan’s wheelset on my Santa Cruz Superlight spoils me. The bearings roll like nothing else, and the SRAM hubs don’t compete. The WTB Frequency i23 rims, though, look like they can take a flogging from a heavy-riding mountain biker. So far, they have.

Other bits: A gold Chris King NoThreadSet. An old set of Hayes Nine hydraulic disc brakes. A Shimano SLX crank, Answer carbon handlebar, Thomson seatpost and an excellent WTB Vigo saddle. Some people complained that the Raleigh XXIX looks goofy with its World War II graphics. Hmph. Maybe it’s because I grew up watching Black Sheep Squadron, but I like it.

There’s really only one thing I’d change: the top tube. I’m 6’2 with a 34-inch inseam. When I stand over the top tube of the XL frame, there’s flesh-to-metal contact (feel free to chuckle and infer whatever you wish). Raleigh could make a nifty bend in the top tube like my XL Santa Cruz Superlight. Boom. Problem solved.

Chris King headset aside, there’s nothing fancy here -- but each part is an upgrade from a regular Raleigh XXIX. It all adds up to a bike that’s one big chunk of fun to ride.
