The four-pot Shimano calipers should have provided plenty of stopping power Dan Milner / BikeRadar Key figures in a Large are the 470mm reach, a 66-degree head angle and a 75-degree seat angle. Trek uses its Mino Link chip in the suspension’s rocker link to give two geometry positions : High and Low.įor the bulk of the testing (and in the geometry chart below) I kept the bike in the Low position, which is around 0.5 degrees slacker than the High position, and a margin shorter too because of how geometry adjustment chips work. This latest generation Fuel EX benefits from a tweak to its shape, with a longer geometry that looks more contemporary on paper. This reacts to the shock’s shaft speed as it moves: faster shaft speeds mean the compression circuit opens up more during impacts, while slower shaft speeds (generally generated via pedalling) lead to a more closed-off circuit for better pedalling performance. Trek has worked with Penske suspension for a number of years, developing the Re:aktiv suspension tune for its shocks. The Mino Link gives adjustability to the bike’s geometry. Seen on carbon Specializeds for a while, Trek also has its own down tube storage solution, located under the bottle cage. Cables are routed internally, with clamped stops. The frame comes with the pre-requisite down tube protection, as well as chainstay protection. This is a keyed frame/spacer/stem system, which limits the rotation of the fork during a crash. This does mean that the down tube could be prone to fork-crown strikes in a crash, were it not for the Knock Block system built in to the headset. Unlike many brands, the tubes are largely straight – both the top and down tube feature barely a curve. Trek has been using carbon for decades, and its OCLV Mountain Carbon is the material of choice for the Fuel EX 9.7. Trek Fuel EX 9.7 frame and suspension details
