29er With Double Crankset

Hi All

I'm in the market for a 29er hardtail and a lot of the bikes that I fancy (e.g. Grand Canyon AL 9.9) come with a double crankset rather than a triple. I live on the edge of the Lake District and tend to ride on the road for 10-20 miles to get into the Lakes before riding off road. My concern is that a 38 chainring will be too small for the road? My current MTB has a 44/32/22 crankset.

Opinions welcomed?

    It probably won't be. You just up your cadence a bit, which is very good for your fitness levels (not that schlepping up a load of hills in the Lakes won't be)

    Thanks Giraffoto. I agree, I think it will be rare for me to be spinning out on a 38/11. Especially with the larger 29" wheels which will increase the gearing anyway.

    A mixture of that and also allowing for the larger gearing of a 29er (big wheels/tyres etc.) it'll be fine.

    I find my 29er, which has 38/24 at the front and 11/34 rear slightly high geared in bottom gear (24-34), I think a 11/36 rear would be better. I'm in the yorkshire Dales, which isn't that different to the Lakes.

    I agree. I will be using a 36-11 cassette.

    You'll be fine - that's almost equivalent to a 42/11 on 26" wheels, which is plenty.

    Thanks for your reply. I have to admit, initially, I hadn't taken that fact that the larger wheels will increase the gearing into account.
