BROKE OVER A WEEK THE BEARING SIZE BORKE THE SEAL AND WAS MOVING IN AND OUT

A bit of bling for my rear derailleurs. Warning not all derailleurs allows these to be replaced. I bought a new set to fit these and found out they could not be fitted. Upgraded the old set instead.

Pensaba que no habría problemas, han durado un mes, el rodamiento se ha abierto y la cadena queda encajada quedando fuera de la guía, mala calidad

Really really good, fits my 9 speed XT Deore with no problems. Its firmed up the gear changing.

Bought these, just a punt, not that expensive. The bearings seem good, and the product is well anodised. But note the external alu covers sit a bit to wide for shimano road. so you can't get the bolts full tight in your rear mech. i think the external plates just need machining a bit closer. i was trying these on 9150 rear mech. might be ok on an older shimano mech.
