DUB WIDE technology
Can I just use older Boost cranks?
No. If your bike is specified as CL55 or chainline 55, our MTB Wide cranks are the only option that will work. SRAM's MTB Wide crank uses a wider axle and Q-factor to provide clearance between the bike's rear forks and chain to allow for proper chain top alignment. Using a standard Boost crank can cause irreparable damage to the rear or lower الواضع (protrusion - the attachment part of the seatpost) of the bike, posing a risk of injury or death to the rider.
Can I upgrade my existing bike to the Wide standard?
An MTB Wide with a 55mm chainline may not be an upgrade for current cyclists. Most new bikes will be built around the 55mm chainline, which is achieved through differences in the design of the rear forks and the rear of the bike. This is only necessary for frames built around this design and requiring higher ground clearance. When in doubt, always check the specifications.
Many frame designers who have used the advantages of MTB Wide in the design of their new frames have also switched to the Universal Derailleur Hanger (UDH). So if you see a mountain bike with a UDH, it's probably designed to take advantage of the space offered by the 55mm chainline.
