Tacx Jockey Wheel -

Great, strong and seem like they will last.

Good quality - but, not sure they're really that much better than the standard Shimano ones that come with my dérailleur!Buy them if you want the best!Otherwise be happy with what you have and save spend your money on a holiday.

Good pieces of equipment there's no side play like original equipment giving rock solid accurate shifts 100% of the time. You need less effort through the lever to make clean gear changes, really good

The high quality reasonably priced pulleys are a simple upgrade to replace the cheap nasty pulleys fitted even to higher end derailleurs.

Does what it says on the tin!Good value. Gear shifting better now worn pulleys replaced. Multi-Manufacture-fit item with clear instructions.

Bien fabricado en 11 dientes. Mejora la duración en condiciones de agua y barro por los rodamientos de inox. Sustituye perfectamente al repuesto original Shimano.

Desempeñan su función correctamente, las compre con ese fin y estoy contento con las mismas. llegaron bien en tiempo y forma

Utilizzate per sostituire le pulegge originali di un cambio x0 a 9 velocità. Fanno bene loro parte. Resistono bene al fango.

Han mejorado mucho el rendimiento del cambio, los viejos ya tenían algo de holgura y me fallaba

Con le rotelle originali del mio cambio avevo sempre problemi nella cambiata. una volta montate queste le cambiate sono perfette!

No ruedan mucho, pero un precio muy bueno para sustituir la original.

Han enviado dos roldanas inferiores. Parece un producto devuelto o reacondicionado.

Nice jockey wheels.Works as a good replacement for the lower jockey wheel only.Upper is completely different and once installed shifting degraded. Kept the lower installed, reused the shimano upper to maintain shifting. Hint, 11 sp shimano is super finiky about non-shimano parts, they never seem to work.

I don't let my drivetrain collect a lot of grunge, but I was still surprised that I noticed the difference when I switched from plain bushing Shimano guide pulleys to these Tacx ball bearing pulleys. Shifting is at least as good as original equipment, with the bonus of less drag and maintenance. These are easy to install and easy to live with, definitely worth having.

Smooth, quiet, perfect shifting

Working perfectly on my road bike with Shimano 105 (5800)

Excellent set of pulleys. They really are smooth and quiet.

Good improvement over stock pulleys. Time will tell about durability.
