I did it on a Brother Kepler Disc last year with 42s. There are fewer sections that would have benefited a MTB compared to those that didn't in my opinion.
Coming down the back of the Corryarick pass was pretty mental though. The only time I wish I'd had some suspension.
Anyone ridden 'Badger Divide' route Inverness to Glasgow. Assessing bike options/suitability of current gravel bike hence post in gravel thread.
Should I repost to routes etc?
