Well, we upgraded my gravel bike “Candy” to be a MUCH better climbing bike (really we turned it from a “cyclocross” bike to a super-light gravel bike). After upgrading the tires, we upgraded the rear cassette (and derailleur) and front chainring.
Hunter figured out Shimano GRX, with a longer GRX derailleur, could take a much bigger rear cassette, all the way from 34 tooth biggest gear to 46T:
We also made the front chainring smaller, from 40T stock to 36T:
Candy now has the same “gain ratio” in its easiest setup:
- 46T (rear) + 36T front – which climbs the same as:
- 51T (rear) + 40T front :)
And, wow she can climb now.
