GRX Limited Edition Flat Bar Build Kit, 170mm (TAKE OFF)

**MOUNTED / NEVER USED**

There is a rich variety in the field of gravel bikes. Among those bikes, there are unique, handmade bikes crafted in steel, titanium, and aluminum that are tailored to meet their owner’s preferences. There we find aficionados who embody bicycle culture and builders who take pride in what they offer.

The new 12 speed GRX is a much-anticipated update to Shimano's gravel shifting range, bringing its gravel groupset that has been predominantly best suited for 2x setups in line with competitors' offerings. After its pre-launch runs in the wild at multiple gravel races, we've now got all the official details of the 12 speed version of the groupset giant's gravel-specific components.

The largest change is obviously the addition of another gear to the setup, in this case meaning the GRX 820-2x series has a 11t smallest sprocket. This has been allowed by adopting the Microspline-free body and redesigning the rear derailleur.

Although the changes are visually minimal, the 12 speed GRX comes with revamped GRX shift and brake levers which Shimano says enhance control through pressure point reduction and increased surface area. They have also been optimized for flared drop bars commonly used by gravel riders.

In conjunction with the 12 speed GRX, Shimano has also introduced a 12 speed 105 groupset to its lineup, and a set of new gravel wheels.
