Get the Junk Out of Your Jockey Wheels!

Muddy race? Dirty trails? Gunked-up drivetrain? Meet Jockey Junk!

After a muddy gravel race, mountain bike adventure, cyclocross event, or everyday ride, your rear derailleur jockey wheels can collect a nasty buildup of mud, dirt, grease, and grime.

Jockey Junk by Shamrock Workshop makes cleaning those hard-to-reach jockey wheels quick, easy, and hassle-free!

No need to remove your chain (which you can clean with our ChainThang), disassemble your derailleur, or spend unnecessary time scrubbing with oversized brushes.

Simply position Jockey Junk against your jockey wheel and use its compact, specially designed bristles to scrub away accumulated dirt and debris.

Less time cleaning. More time riding!
