Without much fanfare, Giant has snuck some modernized updates into their World Cup winning carbon cyclocross bike – the same TCX Advanced ridden by Dutch crosser Lars van der Haar. The bike get updated thru-axle and disc brake standards for smooth compatibility with the latest components and wheels. At the same time that their top bike gets updated, their more affordable aluminum TCX SLR bikes get reworked with those same standards. And for your budding cross grom, a pair of new alloy Espoir bikes will give young riders a solid start. Take a closer look after the break…

TCX Advanced Pro


The new Advanced carbon bikes drop last year’s 15mm front thru-axle in favor of the now dominant 12mm axle standard both front and rear. Up until this season it had been a mix of axle diameters, so now it’ll be time to stick with 12mm end caps for all of the wheels in your cross pits. We already had a preview of the update when we saw the gravel-focused SX version of the bike back in June.

The bikes also switch to flat mount disc brakes. Giant had already been one of the few companies offering compatibility with the smaller 140mm rotors in their previous post mount, but now with the swap to flat mount calipers, riders get an easier and cleaner swap to the rotor size of their choice.


The TCX Advanced comes in two builds. The top TCX Advanced Pro 1 in lime/black (above) sells for $4400/4200€ with a Shimano Ultegra Di2 1×11 drivetrain and Giant’s own CXR1 tubeless wheels. The TCX Advanced Pro 2 is a good bit more affordable at $2575/2400€, sharing the same full carbon frame, fork and D-Fuse SL seatpost but with a SRAM Rival 1 groupset and lower spec house brand wheels.



On the alloy front, the TCX SLR gets the same upgrade to 12mm axles and flat mount discs. That’s an even bigger update here, as last season’s aluminum TCX had still been running QR axles out back. The alloy bike gets a bit of a reworking of its seat clamp as well, to get the same performance as on the carbon bike with the D-shaped proprietary carbon seatpost. Even though the TCX SLR carries over the race geometry and focus of its carbon big brother, it still retains more versatility with fender mounts on the fork, and hidden rack+fender mounts out back.


The aluminum TCX will be available in one or two specs this season, depending on where you are. A black/blue TCX SLR 1 with a Rival 1 group will be available in some limited markets (above), while in the US and EU the black/silver TCX SLR 2 will sell for $1240/1200€ with a 105 double and TRP Spyre mechanical disc brakes.

TCX Espoir


On the kids side of things Giant has a couple of new alloy bikes either with 24″ (orange) or 26″ (lime green) wheels to suit smaller riders. Built around a couple of light aluminum frames with the same ALUXX tubing concepts as the adult SLRs, the Espoir bikes get compact sloping geometry better suited to getting kids into the sport, with more standover.

Matched with the smaller wheels are low Q-factor cranks,  short-reach & narrow drop bars, and bar top brake levers for added confidence. Braking is handled by mechanical disc brakes as well, to keep the bikes under control. The kids’ bikes do stick with QRs and post mount brakes, but at least they do get size-appropriate small rotors.

Their availability appears to be limited as well, although we do see some of them popping up in the US and at least some European markets($710/675€ for the 24″ bike).

    Giant’s questionable departure from 29ers and always leaving out models in the US has made me really question my support of them. They used to be the “newer” Kia of the bike market. Now their stuff is kind of middle-of-the road on price but continues to retain none of the resale value versus other brands.

    great bike. saddle clamp design is atrocious though. you need 15NM and carbon paste to avoid slippage…this is a Cross bike afterall…its telling that Giant changed the head on their dropper post to avoid this problem…sad to see they made all the Shimano-compliant changes to the 2017 but didnt fix the saddle clamp.

      I’ve got a 2014 TCX SLR 2. No problems so far on my saddle rail clamp, although it does work best with 15 Nm on the bolt. Haven’t needed carbon assembly paste on mine.

      The through-axle front and rear on all the SLR models is new for this season (it used to be a front TA for the SLR 1 only) – those look pretty tasty. That said, I haven’t really had any problems with stiffness or rotor rub on my bike’s QR axles all round.

    Single bolt seatpost are stupid for a CX, at least for a CX deemed to be raced, dismounted, remounted. It is not a question of if but rather of when will the saddle point upward or downward after a slightly botched remount.

    people on this site really love to complain. perhaps trying something before you knock it might be a good approach to take…Ive had this bike for a 2 months, raced it multiple times, and ridden in the woods quite a bit. zero dropped chains, zero saddle slipping when torqued to spec, no carbon paste needed.
