Super speedy dinner plates for TT bikes! These are 7075 aluminium "narrow-wide" single (1x) TT rings on 130BCD standard 5 bolt pattern. The intricate narrow-wide tooth design gives maximum chain holding ability meaning it is possible on some bikes to run without a chainguide or front mech. Black anodised with laser etched decals.
54T and 56T rings are machined to order from our solid centre rings so the inside cut out and bolt holes will not be anodised black.
Note that some TT frames are not designed to take very large chainrings. Please check the largest chainring size your frame is designed for (using the manufacturer's specifications) before ordering. We cannot advise whether a particular chainring will fit on your specific bike frame.
Also, some bikes may require a chain guide to prevent the chain from falling off when using a single ring - this is likely to depend on the width of your bottom bracket and the range of cogs you are using on your cassette.
