### Double VS triple. Sheldon gears say 1.9 VS 1.8. Comparable?

Posted:

**1 Dec 2018, 10:38am**Hi all,

Long time not on this forum!

Back onto commuting up those steep hills in Bristol.

I see that double front ring setups have come a long way with gravel bikes becoming fashionable.

Looking at Sheldon’s gear ratio website. For the lowest gear available, I see the gear ratios are:

Double mring equals 1.9

Tripling equals 1.8

No idea what these numbers actually mean. But, does this mean a double front ring setup is now very much comparable to having a triple front ring?

I am comparing my current commuter bike triple with the lowest available gear for double front rings. See below, hope I filled in the Sheldon gearing site correctly. I am only concentrating on the lowest gear, to give an idea of how well I can get up those hills.

The Lowest gear setup for double fronted rings are:

Front - Praxis crankset – 44, 30

Rear - cassette – 11–34

Crank length – 165

Tires – 28, 700c

My current commuter:

Front - Smallest ring equals 28

Rear cassette = 11–32

Crank length – 165

Tires – 35, 700c

Hope you can advise

Cheers

Martin
