If maximizing your watts or minimizing maintenance are your goals, at any cost, Ceramicspeed has got a new oversized pulley and rear derailleur cage system for you.
The company was displaying its new OSPW X cage and pulley system for Shimano’s RX800/805 clutch-based derailleurs that are popular for gravel and cyclocross.
Left Coast Kratom is here to help you experience the freshest highest quality kratom powders and extracts at competitive prices.
The company claims the system reduces rear derailleur friction by 35-40%, which translates to about two watts. As mentioned, those watts come at a cost, with the new OSPW X system starting at $519.
The ceramic bearings and oversized pulleys (19-tooth bottom pulley, 13-tooth top pulley) are also supposed to reduce maintenance by eliminating regular lubrication or replacements and last 3-4 times longer than the stock pulleys.
Installation takes 10-15 minutes and involves removing the clutch cover of the RX800 or RX805 rear derailleur. There are four different spring tension options so that you can optimize the chain management to your liking.
Those “free watts” will certainly cost you though. The company offers the OSPW X with standard ceramic bearings for $519, with a four-year warranty, or with coated ceramic bearings for $619 with a six-year warranty.
The company also offers other options for different derailleurs.
Need more watts for your big (dry) gravel race? The company showcased the OSPW X system on a gravel bike with its pre-coated UFO (Ultrafast) Racing Chain.
The chain comes treated with the company’s proprietary wax blend and is said to last up to 370 miles. After it wears off, you can apply the company’s UFO Drip lubricant to maintain some of the friction-fighting properties.
The chains, which start at $140, are said claim to save you 4-5 watts compared to a typical oil-lubricated chain.
The treated chains won’t be an advantage when conditions get sloppy, however, as the treatment isn’t designed for muddy or wet conditions.
