![]() The seat tube can flex fore and aft a few degrees, and between the tubes are two additional elastomer inserts. The tubes don’t directly touch but are joined by a horizontal shaft and two sealed cartridge bearings. The top tube is split at the seat tube junction and the seat tube passes through it. It provides extra comfort without the weight or complexity of suspension. Unlike Future Shock, Trek’s IsoSpeed Decoupler system is a passive system with no moving parts. The cover at the seat tube and top tube junction hides the IsoSpeed shaft, bearings, and elastomers that allow the seat tube to flex. The top tube slopes down and the seatpost is clamped low to provide ample room for the post to flex when hitting bumps. At the rear, the Diverge relies on high-volume tires and seatpost flex for comfort. ![]() Future shock only suspends the front of the bike. The wheelbase doesn’t change through the suspension's travel and there’s no power loss due to a suspension fork compressing. ![]() Specialized claims that because Future Shock is positioned under the stem, it doesn’t affect handling or efficiency. Springs are also less complex and have less stiction than traditional suspension systems (e.g., an air fork on a mountain bike) and require less force to initiate their travel. Specialized chose to use a coil spring system because it can actively absorb the frequencies commonly encountered on road and gravel without adding excessive weight. Specialized partnered with Formula 1 innovators, McLaren Applied Technologies, to design Future Shock, which uses a spring in the head tube that suspends the rider with 20mm of vertical travel. The Diverge and Checkpoint take two different approaches to improving comfort on gravel roads. The mechanism is hidden by the rubber boot. Checkpoint: OverviewĨr (Base, Sport) / 9r (comp, expert, pro) / 11r (S-Works)įuture Shock is clearly visible beneath the handlebars. Instead, this comparison aims to explore the history of the two bikes, the technology they use, and the features they offer so you can make the right choice. If you’re interested in a Diverge or Checkpoint, how do you choose between the two? Unfortunately, we can't definitively answer which bike is “better” (sorry). Not only are they both high-tech, highly capable gravel machines, but they are also two of the best-selling bikes in the business. When it comes to shredding gravel, there are two bikes that rule the roost: the Specialized Diverge and the Trek Checkpoint.
