GEVENALLE HOUP

Retroshift, the idea of Portland's Adam Kremen with the help of Mark DiNucci, is a new and old item that has been attracting a lot of attention. In a word, it is an analog version of the STI brake lever with the W lever or bar control moved above the brake lever.

Local riders in Portland are all saying that it has the advantage of being able to shift 4-5 gears at once, and the structure is simple and light, and it is also hard to break.

Retro Shift changed its name to Givenalle and began to focus on developing components that match the more diverse dirt riding needs of today's riders, and has grown to become an indispensable manufacturer.

The HOUP has one tooth removed from the top and a spacer placed on the low side to increase the clearance between the rear mechanism and the spokes, preventing the rear mechanism from getting caught in the wheel and breaking. This is especially effective in cyclocross racing.

11s would be reduced by one piece to 10s, and 10s to 9s, but the top teeth are used much less in races, even by professionals. Because the inner low combination is almost never used because the chain tension will be much looser, which means more troublE Also, the outer top is not used unless the track is very fast, so the disadvantage of one less tooth will almost never be felt.

The compatibility is as follows

Shimano 5700
Shimano 5800
Shimano 6700
Shimano 6800

HOUP = Halo Of Ultimate Protection
