Our daughter competes and has been using Butcher Grid front and rear for as long as I can remember. When they changed the compound to Gripton which has a softer sidewall she wasn’t happy with the performance or durability of the sidewall. We bought Minion EXO front and rear but managed to get some of the Blck Dmnd Butchers in June so fitted them 2.6 front 2.3 rear and put the Minions on her spare bike.
Managed to ride them both on the same trails throughout the summer in all conditions with the same pressures 22 front 24 rear and the new Butchers have been great.
She came home from Uni for a couple of hours on Sunday and brought the wheels from the spare bike with her complaining that the sidewalls on the Minions were flexing so has gone back with a 2.6 Blck Dmnd Butcher on the front and a 2.3 Blck Dmnd Eliminator on the rear. I didn’t have a problem with the Minions but I dont ride like her
I was having the same sidewall problems with the 2.8 Butcher on the rear of the Ebike so have gone for the 2.8 Blck Dmnd which seems to have solved it.
