I’ve been looking at the canyon grail as a replacement for my old caad x that I use for commuting and road riding as well as a few forest trails. Am torn between going for the Al 6.0 or the Al 7.0, the difference being tiagra hydraulic groupset or 105 hydraulic groupset for an extra 250 pounds.
I’ve had the previous generation of shimano tiagra, 105 and dura-ace and didn’t think shifting performance was significantly better to justify the cost so in that sense I’d be happy with tiagra from the shifting point of view. However, I have no experience of tiagra or 105 hydraulic discs. Is there much difference in performance?
I’m inclined to say tiagra suits my basic needs perfectly as I don’t want an overly posh bike for commuting but want it to be reasonably nice for occasional sunny days out. But I don’t want to find out that the tiagra hydraulics are rubbish as there’s no way to change just the brakes easily being that it’s 10 speed rather than 11.
Any thoughts? Anyone tried either brakes or own a Canyon grail?
