Rated 3 out of 5 by CheKhonte It's X7 Jockey Wheels of course, but not at all and you have to keep in mind it.
I mean that it is X7 jockey wheel, but X7 made around 2004. Actually it is the same as X5 jockey wheel. Lower wheel have no sealed bearings like in modern X7 jockey wheel. But at other side of the coin is the lower price and it is still work properly. So it's OK, just buyer should keep it in mind.

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...
