I had some jockey wheels which had different adapters including one for 8spd. However, they were too narrow. These 10T jockey wheels were perfect for my Shimano 105 rear mech and 8spd cassette. I fitted them but yet to ride the bike as I am rebuilding it.
Product is as expected and good quality, work well once fitted. Arrived quickly without issue.
Great price,fast delivery,fitted to my 80's peugeot,work really well.
Value for money, good quality and in perfect conditions.
