New low-friction cage choice for SRAM Transmission ‘dynamically extracts particles’ however comes at a excessive worth.
If you happen to’ve splashed out on SRAM’s newest T-Kind Transmission, however search additional potential positive aspects by way of effectivity, the CeramicSpeed’s newest luxurious improve might be for you. Changing your complete cage meeting, the brand new OSPW X is CeramicSpeed’s latest derailleur hop-up.
Priced at €579 (no UK pricing as but), think about a SRAM XX T-Kind mech at €700 (£695), and it takes the potential price of a derailleur to an eye-watering €1,279. In return to your hard-earned, CeramicSpeed claims the OSPW will ‘
present peak efficiency deep in races or within the season when riders want it probably the most’. Definitely we highlighted many benefits of SRAM’s T-Kind Transmission in our first trip evaluate, notably its simplicity of set-up, clean shifting beneath load, and sturdiness, however will probably be fascinating to see whether or not CeramicSpeed has improved on that already excessive bar.
The decrease alloy pulley wheel has 20 narrow-wide enamel for lowered friction and an additional mud guard over the low-friction bearing.
To attain this, the model brings its trademark free-spinning pulley wheels to the desk. On this case 14-tooth and 20-tooth two-piece aluminium pulley wheels with a stable aspect profile that stops sticks getting caught within the spokes, whereas, it says, rising pulley stiffness. Additional safety comes from the stainless-steel mud shields, that maintain filth and grit away from the bearings with out resorting to contact seals that enhance friction. And the narrow-wide profile enamel are created from a composite materials that’s mentioned to be sturdy and quiet. Along with the low-drag bearings, CeramicSpeed’s decrease pulley wheel is 4T bigger than SRAM’s at 20T, which reduces chain angulation because it wraps the pulley, which can assist scale back friction.
CeramicSpeed’s OSPW X derailleur cage is offered with a silver pulley wheel cowl, or…
Across the bearing is a characteristic CeramicSpeed is looking ADR, or Lively Particles Removing. Described as a bladed groove construction that successfully chews up and spits out something that will get wedged between the cage and the pulley. It sounds a bit like one thing Boudica would have sported on the wheels of her chariot, however is definitely impressed by rotating snowploughs. Whereas SRAM makes use of a two-piece pulley wheel the place the enamel can proceed to rotate even when the spokes are jammed, ADR, together with the mud shields, is actually an easier system. With no holes for particles to get caught in, the pulley shouldn’t have the ability to jam, though we’ve but to check its effectiveness ourselves.
…black pulley wheels.
Total weight for the cage is claimed to be 111g, and becoming appears to be like to be easy. There’s no have to take away the derailleur from the bike, or regulate the size of the chain, and solely the rear wheel wants to come back out. A few bolts to take away and reinstall and also you’re away, with maybe the most costly derailleur ever made (this aspect of a Paul’s mech from the ’90s) hanging from the dropout of your bike.
