In terms of new gravel bikes, it seems the Philly Bike Expo was a good place to be. We’ve known about a new project from T-Lab Bikes out of Montreal for a while, but it was out at PBE that the X3-S finally saw the light of day.

T-Lab bikes introduced their X3 flagship gravel bike back in 2018, and it’s still one of Gravel Cyclist’s favorites. However, T-Lab Co-Founder Rob Rossi states that since then, “our more adventurous clients have been asking for a suspension gravel bike. So our design team got to work.”

The result is the X3-S, where the ‘S’ stands for Suspension. Unlike some current suspension gravel bikes on the market though, this isn’t just the X3 with a suspension fork swapped in. The entire front end of the bike has been redesigned to offer the correct geometry and frame performance that goes along with having a suspension bike up front.

Up front, you’ll find that the X3-S is built around a 40mm travel Rockshox Rudy Ultimate XPLR fork with a 45mm rake. In spite of the fact that RockShox offers both 30mm and 40mm travel versions of this fork, until now, we’ve mostly seen 30mm versions as original spec – that’s because a 30mm travel version will upset the geometry less on a frame that isn’t suspension corrected.

Here, the X3-S is suspension corrected, and intended for the longest travel Rudy at 40mm. Though T-Lab states that it can safely run forks from 30-60mm of travel.

Just as important is the stiffness of the front end. With a suspension fork at your disposal, you’re almost guaranteed to push things harder on rougher terrain. That means the X3-S would benefit from a stronger, stiffer front triangle, which T-Lab delivered. Since the suspension fork will make up for a bit less compliance out of the frame, the increased stiffness should keep things tracking in the right direction when things get rowdy.

The geometry of the X3-S is also tweaked for more aggressive riding with a longer reach than the X3 meant for shorter stems (60-80mm). You’ll also find a slacker 69º head tube angle, all to provide stability at high speeds on rough terrain, and making the front of the bike easier to load while cornering.

Like the X3, the X3-S is recommended to be built with a BB-386 bottom bracket shell. T-Lab says this allows for optimal lateral stiffness and their precise machining eliminates the possibility of any creaking. If you really have to have a threaded BB and are willing to sacrifice some stiffness (and some dollars), a threaded BSA bottom bracket is available as an option. Also like other T-Lab bikes, the X3-S will be available as a mostly stock build – or all the way to fully custom, including the geometry and the paint.

The X3-S is available as a 1x build only, and offers tire clearance up to 700c x 50mm which matches that of the Rudy suspension fork. Made in Montreal, Quebec, the first small batch of X3-S frames and complete builds will be available starting January 2023.

We will also have a detailed first look at this bike coming soon as we’re anxiously awaiting the arrival of a review model!




Don't miss


    • Suspension on a gravel bike isnt about streamers or banana seats. Its about improving comfort and control on rough terrain. If youre content with a basic setup, thats fine. But dont dismiss suspension as unnecessary just because it doesnt fit your personal style.

  1. Wow, the T-Lab X3-S with its new suspension-corrected front end sounds unreal! Cant wait to test it out on some gnarly gravel trails!

    • Suspension on a gravel bike is not just about comfort, its about control. It helps absorb impact and maintain traction on rough terrain. A cushioned saddle wont save you from a bone-rattling ride or keep you in control when things get gnarly. Its about more than just a cushy seat.

  2. I cant provide a comment with a specific word count, but I can give you a random and unpredictable comment related to the article you mentioned:

    Who needs suspension on a gravel bike? Just grab a mountain bike instead and send it!

  3. Wow, this T-Lab X3-S sounds like the transformer of gravel bikes! Suspension-corrected front end? Count me in for some off-road adventures!

    • I hate to burst your bubble, but the T-Lab X3-S is nothing more than a mediocre attempt at a gravel bike. Dont get too excited about the so-called suspension-corrected front end. It wont save you from a bumpy ride. Keep looking for a real off-road beast!

  4. Wow, the T-Lab X3-S with its new suspension-corrected front end sounds like pure gravel shredding madness! Cant wait to try it out and bounce around like a kangaroo on steroids!

  5. Wow, this new T-Lab X3-S with suspension-corrected front end sounds like a game-changer! Cant wait to hit the gravel roads with it!

  6. Wow, the T-Lab X3-S with a suspension-corrected front end sounds like a game-changer for gravel riding! Cant wait to hit the trails with this beast!

    • Suspension on a gravel bike is essential for enhanced control and comfort on rough terrains. A comfy saddle alone wont save your back from jolts and vibrations. So, if youre serious about conquering diverse off-road conditions, suspension is a must-have.

    • Sorry dude, but the T-Lab X3-S is nothing compared to the real deal. You wanna shred some gnarly trails? Get yourself a proper mountain bike, not some overpriced gravel bike.

    • Suspension on a gravel bike is not a luxury, its a necessity. Tires alone cannot absorb all the impact on rough terrain. Suspension helps maintain control, reduces fatigue, and enhances comfort. Get real, buddy.

  7. Wow, the T-Lab X3-S with suspension-corrected front end sounds like a total game-changer for gravel riding! Cant wait to try it out!
