Is your Race Inc bike axle moving or sliding making your chain loose? Well Billet BMX has you covered with our Chain Tensioner kit. This kit was designed to solve this issue and was specifically made for the Race Inc 20mm dropout frame. 

Billet BMX chain tensioners feature an internal bolt that does not stick out like other brands on the market. The Shield slides front to back with adjustment making it easy to match axle position on both slides using numbered markings. These are made from 6061 T6 aluminum that are fully CNC machined. The 20mm Washer/Adaptors are made from Stainless Steel for Maximum Strength. The CNC parts are tumbler polished then bright dip anodized for glossy appearance and corrosion resistance. They are finished with Laser engraving for high end detail. 


  • 20mm RACE INC Frame with 10mm Axle
  • 6061 T6 Aluminum Full CNC Tensioners
  • 20mm Stainless Steel Washer/Adaptors for 10mm Axle
  • 47mm of Adjustment
  • Stainless Steel Hardware
  • Anodized
  • Laser Engraved
  • Sold as a Kit (2 Chain Tensioners and 2 Washer/Adaptors)
  • Patent Pending


Note: Not recommended for use with Pegs. Shield may hit peg when adjusting chain tension depending where axle sits in dropouts. Moving axle towards front of bike in dropouts by shortening chain will move shield slider farther from axle allowing more clearance for pegs. Shields are also removable to get more clearance if needed. Many of our customers do have our Tensioners installed with Pegs but modification to the chain may be required for proper fitment. Billet BMX is not responsible for clearance issues with pegs.

Better than expected

The quality on these tensioners are awesome. My wheel doesn’t move due to the adapters and tensioners, plus they look amazing on my Raceinc.

James Barbee

Nice stuff recommend it all day

Bill Nicholson
Great problem solver!

Worked great to run 10mm axle hubs on the new Race Inc frames. Clean looking too - I like the internal bolt design.

Great products and great service

Mark Baricko

Very well made , great design, would be much easier to install if Race Inc had straight dropouts on the frame, need to spread the frame to get them on.
