2018 Men's Stumpjumper ST Alloy 29
£1800.00
Alloy loyalists rejoice! The new Stumpjumper ST Alloy 29 represents a short-travel frame with all the agility of its S-Works older brothers. Radical new shape designs and exciting new tube profiles promise to grant riders a trail bike experience like no other. Nothing is purer than the simple bond between a rider and their bike, a telepathic connection between human and machine creating an exhilarating ride experience. This connection is something we set out to achieve with the new Stumpjumper, in the hope that it would live up to the acclaimed title of ultimate trail bike'. We found that the key to rider-bike telepathy is stiffness, so we focused in on the shapes and materials of the frame that would allow us to get to work on achieving such stiffness. Though suspension and stiffness are sometimes thought of as counteracting forces, a balance between the two features is vital in the pursuit of ultimate' trail bike credibility. A custom Rx Trail Tune on both the fork and rear shock lets the rider fine-tune their ride, with a specific Rx Tune for each wheel size platform to accommodate even the pickiest of riders. Whatever wheel size you choose, the Rx Tune will ensure you'll get perfectly linear suspension every time. Major efforts have been made to make this bike not just great fun, but also a constant and flexible companion. We've brought back the threaded bottom bracket and made room for a 3.0 tyre, ensuring that you get the most versatility out of your new trail bike. The components of the Stumpy are also easily upgradable, none more so than standard metric shocks that allow complete freedom when considering future rear shock upgrades. Want to dial in your Stumpjumper ST Alloy 29 to suit your personal riding style Just flick the Flip Chip and you'll drop your bottom bracket and slacken the head tube in no time, perfect when navigating the more technical bends and berms on your favourite trail. A ribbed chain stay protector assures peace of mind, anger-inducing chain slaps now a thing of the past. If high-performance at an attainable budget is your kind of thing, the Stumpy ST is the perfect alloy alternative to keep the everyman smiling from one trail to the next. The Shimano SLX front and rear derailleurs, a custom X-Fusion 02 Pro RL rear shock boasting 120mm of travel, and wide alloy wheels all come together to create an impressive but affordable build that it is impossible to turn down.
- The all-new alloy Stumpjumper ST frame features an M5 alloy front- and rear-end, an asymmetrical design, and our 29 Trail Geometry, so it's both capable and comfortable.
- The X-Fusion Metric rear shock features rebound adjustment, lockout, and our coveted Rx Trail Tune to ensure you're getting the most out of your Stumpjumper ST.
- A RockShox Recon RL provides 130mm of travel up front, and it lets you adjust both rebound and lockout.
