Some may say the original RoubX rim is an overkill for gravel and light XC, yes, we know it can do more, and this is how the story of the new G33-B wheelset began. The new M1 Boost hub changes the character of the wheelset entirely - 102T engagement for lightning-fast reaction, wide and tall angles ensure robust wheel geometry. With all rim features inherited from the original RoubX, extra toughness and steering precision, the G33-B is a MTB wheelset you can trust.
