Having said that I have the feeling the cotic is just a tad light for the Alps!!
AQR use Cotics for guiding in the Pyrenees and they stand up to that just fine. They’ve got a couple of Hemlocks as hire bikes as well. Unless yours is built particularly light I reckon it’ll be fine…
The guide bikes probably see more mileage in a year than most peoples bikes will see in 5 years, in fact Cotic use AQR for product testing. If a Hemlock can go for a year of constant use in the Pyrenees, it’ll do 2 weeks in the Alps with you!
