Well to give you a bit more detail.
Mate bought a Scott (he posts on here too)
When he took in for first service, they left him with only 9 gears instead of 10, saying “can’t quite get it to work right”.
They left his lockout cable frayed and all over the place at top of fork leg.
They then sent them to Mojo to be repaired.. 8 days after saying “they’ve been sent, they were still in the workshop”
After completion, he still didn’t have 10 gears… he then brought to me and I got him all 10 in about 40 seconds upside down in his front garden.
That for me instantly said “Stay away”
As for Mountain Mania in didcot, I called them up wanting a PF30 on a Friday afternoon. The guy then drive 45 miles that evening to their other shop to collect it for me, drive back in the morning and fitted it by 9.30am All in all, excellent service.
