I have the SLX and I can't fault it. Had it just over a year and still going strong. I would 100% recommend the SLX for spec and value for money. The new Bosch update has made it a beast and is easily on par with the Amflow.
I'm at 4k km, bike has been ridden hard, all issues documented here, need to tighten the bolts after first few rides, some headset creaking I can't get rid of, but still a great bike for the price
