Apparently, Kogel says the 10-44 XPLR cassette and requisite 1x drivetrain setup the SRAM XPLR group calls for isn’t only for gravel, that it really works very effectively for triathlon and crit racing, too…albeit with a bigger chainring up entrance.
So whether or not you’re racing across the metropolis blocks, from T1 to T2, or as far-off from pavement as you may get, their new Kolossos SRAM XPLR derailleur cage places ceramic bearing-equipped oversize pulleys underneath the derailleur.
Kogel’s stiff, machined alloy cage maintains (they could argue improves) shift efficiency whereas delivering decrease drag. The bearings get their low-friction highway seals to reduce system drag, however you possibly can add their heavier responsibility ‘cross seals if you already know you’ll be slogging via dangerous climate or deep mud.
They are saying it’s the shortest pulley cage they’ve ever made, designed particularly for the XPLR rear derailleurs, regardless of how you employ them.
A narrow-wide decrease pulley aids chain retention, and tooth counts are 15 (higher) and 18 (decrease). It’s accessible in uncooked and black anodized colours, retail is $475 (pre-order pricing is $375). It matches each Pink and Power XPLR eTap AXS derailleurs.
