Get the comment about bearings, but unless they are ceramic they just seize after the first wet ride, so these are perfect replacements.

Too much friction with plane bearings and wear out in no time. For £3 more you can get Rollerboys with cartridge bearings in both pulleys - probably the most cost effective upgrade I ever made...
