Historic manufacturers Renold are offering a limited number of their ultra-efficient chains used by the British Olympic team to the public – but it’s going to set you back a few quid.
British Cycling approached the Manchester-based firm in 2011 after they identified problems with their existing equipment.
Renold were tasked with creating an super-efficient and hardwearing bit of tech, fit for Britain’s Olympic track stars.
The result was the 138 Velo CT single-speed track chain.
Engineering director at Renold, Detlef Ragnitz, said: “British Cycling came to us with some very interesting and specific challenges.
“Elite athletes make extreme demands on the chain. We looked at our technology portfolio to see what might be a good fit.”
The design was based on Renold synergy technology, which is widely used in the industrial sector due to its efficiency and durability.
Ragnitz added: “In industrial applications, greater efficiency means reduced carbon footprint.
“In cycling, it means more speed.”
The chain has a specially treated pin and bush to improve efficiency and reduce wear.
Its side plates are precision-formed and holed, before they are pre-stressed.
The plates are then nickel-coated before assembly to prevent corrosion.
Head of technology for the Great Britain Cycling Team, Tony Purnell, said: “Any loss of drive train efficiency means that some of the power from the riders’ legs gets wasted into heat, so it absolutely makes the bike quicker.”
The chain was used by the British track team at the 2016 Rio Olympics, where they picked up six gold medals.
Purnell added: “We knew when we were on the starting gates in Rio, we had the best chain in the world.”
In 1880 engineer Hans Renold invented the bush roller chain, which took the bicycle into a new world of efficiency and flexibility.
The basic technology is still used around the world.
Renold are selling a limited run of 138 sets of the Olymic-standard chain to mark the 138th anniversary of founder Hans Renolds invention of the bush roller chain in 1880.
But the single-speed chain will cost you, as the price is £250.
