TREK Supercaliber SLR 9.8 GX AXS Gen 2 – Deep Smoke

R145,000.00 INC VAT

The Supercaliber SLR 9.8 GX AXS is an ultra-light carbon XC mountain bike that’s ready to lay down rubber on race day. Its SLR Mountain Carbon frame is as light as it is meticulous, with a high modulus lay-up that gives you all the stiffness you crave, and none of the weight. XC courses get rowdier every year, so it’s equipped with a 110 mm fork and 80 mm of IsoStrut rear suspension to smooth your roll without kicking pedalling efficiency to the wind. It’s all topped off with carbon wheels, a carbon cockpit and SRAM’s wireless GX AXS Transmission.

Disclaimer (Warranties):
I understand that my bicycle needs to be built by an authorised dealer for the warranty to be valid and that it is best to practise for me to fit and inspect the bicycle in-store.
Disclaimer (Size):
I understand that some bicycles are ordered according to size. The size I have provided is my confirmed and correct size, and I will not request a refund should the size I have ordered be incorrect. It will be my responsibility to sell the bike before I order a new size.
Disclaimer (Online Orders):
I understand it is best practice to visit my local BSC to fit, order, collect and set-up my bicycle rather than opt for shipping.


TREK has this rule: if it’s not built by an official TREK retailer, there is no warranty for you.

We’ve got your back! Just pick out your favourite TREK bike on our website, and we’ll shoot you an invoice. Once you settle the bill, we’ll work on building your bike in-store for FREE, pack it up, and ship it straight to your doorstep. Easy peasy, right? No fuss, just an awesome new bike day!

Madone SLR 7 is the ultimate race machine. An 800 Series OCLV Carbon frame with exclusive IsoFlow technology adds an aerodynamic advantage, cuts weight, and smooths the road ahead.
