Shimano Ultegra HG-800 11 speed

Unfortunately, the 11-34 isn’t Ultegra quality (please bear this in mind when ordering). The cassette is heavy and couldn’t be adjusted without making noise, as a) the shift teeth rub against the chain from above (very tight fit) and b) resonance is caused by the spider arm. Unfortunately, it was a bad buy. Delivery from Mantel was excellent!
