PRODUCT DETAILS
A more comfortable riding experience with rigid and lightweight construction
Made from 6061 T6 material, with a thinnest wall of 1.3mm on the down tube and 1.0mm on the top and middle tubes using three-segment drawing technology. The forging process is divided into sections for a strong tire capacity without sacrificing pedal rigidity.
Good compatibility with more options
ROCK CRUSHER AL is compatible with both 29"2.4"/27.5"3.0" 27.5PLUS specifications. It is also compatible with internal cable routing and height-adjustable seatpost, with a RC length of 440mm for better stability on challenging downhill sections. With the same BOOST148 specification and compatibility with side-pull front derailleur installation and BSA threaded bottom bracket, maintenance and modification is very convenient.
