It’s a proper Shimano M8000 crank which is a 2 ring crank.
Few mm won’t cut it unfortunately so moving the EBB across a few mm won’t make a real difference.
Not really keen to fit a boost crank as have just paid out £125 for the M8000 one which has been fitted so can’t really be returned. Also not sure that 3mm is going to be enough to stop any rubbing and sucking (oh er) when riding!
Does anyone who is running a double upfront care to share which tyres they are using as I know different makes and models come up differently on size and I’m running 29×3 Knards so possibly switching to a different one might help 😕
