Super speedy dinner plates for TT bikes. These are 4mm 7075 aluminium "narrow-wide" single (1x) TT rings in three different patterns; 130BCD 5 bolt, 110BCD 5 bolt and 110BCD 4 bolt. The intricate narrow-wide tooth design gives maximum chain holding ability meaning it is possible to run without a chain guide or front mech. Black anodised with laser etched decals.
130BCD 5 BOLT
Pre-cut and completely anodised. They will fit the majority of 130BCD 5 bolt cranksets.
110BCD 4 BOLT
Pre-cut and completely anodised. They will fit 110BCD 4 bolt cranksets and the newer Shimano 110BCD 4 bolt cranksets (105 R7000, Ultegra R8000, Dura Ace R9100 onwards). The cut out has been enlarged to avoid clashing with the crank arm.
If you have a 110BCD 5 bolt, an older Shimano 110BCD 4 bolt, SRAM hidden bolt crankset or require a specific cut out please select this option and email us at email@example.com with your specific requirements. E.g if you need your cut out to suit a Pioneer powermeter please order as normal but email us with your requirement.
These are machined from a blank chainring to suit your individual order. As a result the internal cut face will not be anodised black. Please allow for a longer delivery timescale with these individually manufactured chainrings.
If you are unsure which chainring you require please email us at firstname.lastname@example.org.
If the 130BCD 5 bolt and 110BCD 4 bolt are out of stock but the blank are in stock you can order a blank ring and request a 130BCD 5 bolt or 110BCD 4 bolt cut out.
