Gates CDX Carbon Timing Belt System

sku: CR0200-220

Gates Center-Track Timing Belt Kit



The Center Track (CDX) timing belt system from Gates Carbon Drive is one of the best performance upgrades you can install on your tandem. This timing setup reduces overall weight, reduces maintenance and lasts longer than an equivalent chain drive. There is no stretching, no rusting and no lube required. That means no more greasy chain tattoos on your legs!

Your tandem will need to have a bottom bracket center distance of 28.5" (724mm) to use either kit listed. This distance is measured from center of the eccentric shell to center of the stoker bb shell. Most stock sized Co-Motion tandems have this configuration already. Your tandem cranks need to have 5-bolt and 130bcd spiders on the timing side, or 4-bolt and 104bcd pattern. It is recommended that you have 68/73mm bottom bracket compatible cranks like the FSA Gossamer or SL-K models, Truvativ Firex, and Co-Motion compact cranks to help with clearance between the rings and frame. Contact us for any assistance or questions about fitment.

  • 2 Gates CDX Center Track rings
  • 1 Gates CDX Center Track Carbon Tandem Belt
  • Chain-ring bolts/ nuts
*Please specify in the drop down menu;
