Super speedy dinner plates for TT bikes!
These are 7075 aluminium "narrow-wide" single (1x) TT rings for road use. The intricate narrow-wide tooth design gives maximum chain holding ability, meaning it is possible to run without a chainguide or front mech. Black anodised with laser etched decals.
Please note that chainring bolts are not supplied.
Pyramid Cycling Design
Pyramid Cycle Design is a micro business based in Coventry, UK. We are passionate about all types of cycling and want to make the fastest and most innovative products on the market.
Dr Mark Pharaoh established a composites consultancy business, Pyramid Composite Design, in 2012. Before that, he spent nearly 20 years working as a senior research fellow at the Warwick Manufacturing Group (WMG) at the University of Warwick, working on various automotive and aerospace projects involving thermoplastic composite materials.
We were already working on developing bespoke carbon/PEEK chainrings when a chance conversation at Club la Santa in Lanzarote in January 2015 with Dame Sarah Storey and her husband Barney about her impending hour record attempt led to us making bespoke chainrings and adaptor plates for Sarah's hour record bike and spare. The adaptor plates were needed to fit a 144BCD track ring onto a 130BCD Verve Infocrankroad crankset, with special cut outs in both the plates and the rings for the ANT+ transmitter on the crank arm.
From those early prototypes, we have developed a range of bespoke and off the peg carbon/PEEK and aluminium chainrings, supplying them to all levels of cyclists for road, TT, cyclo cross and mountain biking.
We are especially proud to support the Huub Wattbike Test Team as they take on the world (and Team GB) at team pursuiting.
We also supply our chainrings a number of other professional athletes and teams, including: Storey Racing, Team Denmark, Maloja Pushbikers, Albert Torres and Sebastian Mora, Ribble Pro Cycling, Born to Bike-Bridgtown Cycles, Team Bottrill, MI Racing, Vittoria Bussi (women's hour record holder), Cycling Australia's track squad for the 2016 Rio Olympics and professional triathlete Fenella Langridge.
