Shimano Ultegra RD-R8050 Tension & Guide Pulley Set
Quote | Reply
Has anyone pulled apart the Guide Pulley Set for an Ultegra RD-8050 Di2 setup yet? Curious as to if the pulleys are riding on acutal bearings, or did Shimano use plastic races like they did in the the previous model group to keep the price down. TIA
