Description
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 a time, and the structure is simple and lightweight, and it is also hard to break.
Givenalle changed its name to Givenalle and began to focus on the development of components that match the diversified needs of dirt riding, and has now become an indispensable manufacturer.
GEVENALLE GX1
Since Shimano released MTB components with 6 speeds 30 years ago, the number of speeds has steadily increased, finally reaching 11.
While there was almost complete compatibility between road and MTB components up to 8 speeds, it became slightly dubious at 9 speeds and completely disconnected at 10 speeds when the name Dyna-sys was introduced and the components and shift wire pulls completely changed, making it impossible to run a 10-speed MTB shadow rear derailleur with a road STI lever.
This is a big problem for some enthusiasts, as it means that the combination of a shadow rear derailleur with a stabilizer and a wide gear ratio cassette of up to 36T to control chain wobble cannot be used on a drop handlebar.
In addition, wide narrow chainrings, which have rapidly become popular, are only effective in preventing chain fall when used with a rear derailleur that has a stabilizer function, and cannot demonstrate 100% of their power when used with a normal rear derailleur.
Therefore, there was a wall to realize the use of a 10-speed shadow rear derailleur and wide gear ratio cassette in MTB and fat bike drop handlebars, cyclocross, monstercross, and gravel grinders.
GX G is for Gravel, short pull compatible brake levers and SHIMANO Dyna-sys or SRAM MTB compatible right shifter set.
