No problem, thanks. But I did come back a few days later to buy an 11speed Shimano Derailleur. The store did not have any, the shop assistant told me it was because they were hard to come by and shimano probably doesn't have any either and tried to get me to change the whole system because shimano has changed the pull ratio etc etc. Turned out it was all lies and sales talk. Went to the next store (not a 99 bikes), they said of course we have them and of course shimano is still making them and supplying them. I love bikes, I love your stores, I shop there all the time but I do not appreciate that type of nonsense in my shopping experience.
