Kogel’s latest ceramic bearing pulleys give SRAM Transmission riders a bigger, more colorful option for modding their rear derailleur.
The alloy pulleys use the stock cage on GX, X0, XX and XXSL Transmission derailleurs, but increase the lower pulley tooth count to 18, up from SRAM’s stock 16-tooth unit. The upper pulley remains at 14 teeth, same as stock. Kogel says there’s no need to lengthen your chain with that small of an increase.
Available in six colors (black, blue, red, gold, raw, and purple), they retail for $199.99 for the set.
Pair these pulleys with their recent pre-waxed chain for maximum friction reduction, and keep an eye out for bundle deals…Kogel frequently has discounts when you buy a bottom bracket with pulleys or their Kolossos oversized pulley cage.
