First Impressions: Bontrager Switchblade Race X Lite Fork

October 2nd, 2006 by Guitar Ted

I have gotten to mount up the Switchblade Race X Lite ACC Carbon fork and I have gotten a few rides on it. Here are my first impressions of it.

The fork installation was a breeze. Nothing out of the ordinary. I managed to save some weight by installing this fork over the previously installed Inbred 29″er steel fork. The Inbred fork with an eight inch long steer tube and star nut installed weighed 1225 grams. The Switchblade Race X Lite weighed 950 grams for the same length steer tube and star nut installed. After getting the head set adjusted, it was time to start riding it.

The first few shakedown cruises were commutes back and forth to work to get a handle on what I might expect out on the trail. The first thing I noticed was that road feel was damped out and smaller vibrations were not there that I had felt with the Inbred steel fork. Steering was a bit different too. More on that in a bit. When I slammed the front disc brake, I noticed that the fork really wasn’t flexing a whole lot at or near the crown, like alot of forks do. Instead, it was flexing backwards more and more as I looked closer to the drop outs. Almost in the same manner that a fishing rod might flex. Hmm……different!

The flex was backwards about a half to three quarters of an inch at the drop out. This was in almost nose pick mode, mind you. Normal braking didn’t see that amount of flex. Once I was satisfied that there were no funky handling quirks on road, it was time to delve into the singletrack.

The previously mentioned damped feel on road was also noticed off road. Vibrations that might “buzz” my hands with the steel fork simply were gone. Not a really big deal. I suppose my hands could still get numb after a bit, it’s just going to take longer with the Switchblade on the bike. More importantly, I noticed a big difference in handling around corners.

The Inbred fork has more offset, the Switchblade has less offset. This manifests itself in how the bike handled turns. With the Inbred fork up front, the turns required less input and body english. The corners were negotiated with a more solid, carving type of feel. With the Switchblade, the feel was one of a need for more rider input. I had to “set” the bike up for the corner and it seemed the steering was more from the hips. It liked to snap the back end loose more and had a “flat tracker” kind of feel with the Switchblade. Counter steering seemed more intuitive with the Switchblade. It also seemed that the bike steered better with more lean into the corners. All in all a very different feel.

This is because of the offset more than anything, I think. The offset of the Switchblade gave the bike more trail, and thus a bit “slower” handling. That’s not necessarily a bad trait, it just might not be your cup of tea, that’s all. A “slower” handling bike could also be said to be “less twitchy”, so it’s a matter of degrees in handling. the differences not being so great that it was unrideable either way. But it sure gave my Inbred a different personality!

That’s about it for this installment. I have to wring out this fork some more on some different trails for awhile before I post some final observations. Look for another update in a few weeks. Also, look for another carbon legged beauty to show up for testing on Twenty Nine Inches in the near future! Stay tuned!

    Ted, I noticed the same thing with the flex when braking. Is that still a problem for you? Its odd, if the disk starts to shudder, the flex is visable, weird.

    dave hill: Yeah, I was using a 185mm rotor on that fork too, so a smaller rotor may set up a different frequency and not shudder like it did with the bigger 185mm rotor.
