Went out yesterday after i ended up putting the 1 mm spacer on the cassette as the shifting had never been crisp and rumbled, after looking i saw even though the lock ring was tight there was a smidge to much play in the cassette .
Even though i was not pushing at 100 % i managed to better the average round my standard short loop of 23.5 miles in 1 hour and 8 (and a bit ) minutes.
The shifting was slick again and the wheel did not seem to vibrate with the road surface so i am a happy bunny !
