CeramicSpeed has applied its same over-sized pulley technology to the off-road, offering the same friction-reducing upgrade to the gravel and roadplus segments.
“Developed in response to requests from riders and a natural progression of both the OSPW Systems and off-road categories, the OSPW X for SRAM Rival and Force 1 Type 3 is ready to ship immediately. A wide range of cyclocross professionals and gravel enthusiasts fed into the project, including extensive testing with WorldTour professional Mads Christensen and Tom Pidcock, the new UK Elite Men’s Cyclocross National Champion, who has the system on his training bike and one of his race bikes”, says CeramicSpeed.
However, according to CeramicSpeed, its new OSPW X system currently works with only SRAM’s 1x Rival and Force clutch-equipped Type 3 rear derailleurs, which offer enough drag to maintain the necessary amount of tension in order to avoid chain dropping.
“The OSPW X is the first oversized pulley wheel system available on the market compatible with a clutch derailleur. Previous testing demonstrates that clutch derailleurs have higher drag than a non-clutch derailleur. But, through lowering the spring tension (as CeramicSpeed does with the OSPW X), the efficiency gap can be reduced while retaining the overall benefits of the clutch (chain retention on rough roads and 1X chainring setups), resulting in 30-40% less friction than conventional systems”, the Danish company adds. CeramicSpeed.
“The effect is the clutch is a separate function from the backwards spring tension, so each can be adjusted separately to reduce chain drag. Unlike other recent entrants to the market, the CeramicSpeed OSPW X incorporates a carefully designed and tested pulley tooth profile with a narrow/wide design for durability and shift quality.”
Designed, developed and hand-built in Denmark, the new OSPW X features a custom-designed, lightweight carbon fiber pulley cage, which carries a warranty of up to six years and gives a claimed three to five times longer lifetime over a conventional pulley wheel system.
The OSPW X sells €480, which is available with either standard ceramic bearings, or coated ceramic bearings for an extra €80.
As far as future options are concerned, CeramicSpeed likely has plans to further develop the system so it can work with derailleurs from other manufacturers.
“It’s a fantastic step for us… the first step of many as we aim to bring our knowledge and expertise to the off-road segment”, says the company’s vice-president Martin Banke.
