Haven't been around for a while, starting to get back after a few injuries.
Need some advice from the mech experts among us. I had my SRM stolen a few months back Dura ace 7900. Was off the bike getting serviced and it was pinched from work. Made me feel physically sick.
Anyway after moping around I emailed SRM Oceania to see if they had any reco units etc. They were great and sent me out what I thought was a 7900 unit when it arrived it was a 7800 unit (brand new). They have looked after me on the unit however my LBS was worried about it being compatible with my 7900 groupo and also sourcing the 7800 chain rings, Shimano are potentially not making them moving forward also all my spare parts and other bikes are 7900.
So I have two options keep the brand new 7800 unit or return it and purchase a second hand 7900 unit? Both will work out to be the same cost.
Thanks in advance for the advice.
