Mountain Bike Action Bike Test: Giant’s Custom Reign Enduro Bike

 

 

a RockShox Yari RC DebonAir fork and Shimano Deore components. The Advanced Pro features top-of the-line Fox Factory suspension and a lightweight carbon wheelset. Our custom build stands high on performance while landing at a price right in the middle of these builds.

With our custom Reign, we added the pedal power with a mix of Shimano and TRP components for the drivetrain. We took advantage of the TRP TR12 rear derailleur/shifter with a Shimano crankset/chain. However, readers should note that TRP does not recommend using the TR12 with a Shimano 12-speed cassette that goes up to a 51-tooth as we did. Nonetheless, it proved to function fine during our testing with no failures. We also stuck with TRP’s latest DH-R EVO brakes for a system that you can read more about on pages 56–57 of this issue. Everywhere else on this build we used quality Deity and OneUp Components. Sticking this 35-pound brute to the ground are 27.5 × 2.6-inch WTB tires wrapped around Industry Nine’s Enduro S Hydra wheelset.

SUSPENSION

Our Reign’s drivetrain is built up with a mix of reliable components from Shimano, TRP, and OneUp.

The Reign’s frame is designed to run 160–180mm of travel at the front. We ran the latest 2021 Fox Factory 38 with a 2021 Fox DHX2 coil shock at the rear (see pages 74–75 for details on the new Fox 38). The proven Maestro suspension has four strategically positioned pivot points and two linkages that work together to create a single-floating pivot point. By design, this is to create an active and efficient suspension system. Even with heavier compressions, the rear end doesn’t seem to sink and allows us to carry speed in berms and literally plow over any sort of obstacles.

GEOMETRY

A long frame, medium-long chainstays and a long wheelbase are the beginnings of a rowdy rig. So, what have engineers changed to keep up with this trend? From 2019 to 2020, the Giant Reign 29 got some big geometry updates. While keeping the 65-degree head tube angle, the team at Giant steepened the 29er’s seat tube by 3.8 degrees, bringing it up to 76.8 degrees. This was to move in a direction that improves pedaling performance for enduro racing while in a climbing position on the bike.

Between 2019 and 2020 there were no changes to the geometry on the 27.5 version of the Reign. As for 2021,…
