Gear Range % Cassette vs Hub Gear

Gear Range % Cassette vs Hub Gear - Intro

I have found it tricky working out how much range I will loose by switching to a hub gear from a 1 x 9 set up on an mtb. Sturmy Archer and SRAM express there gear hub range as a percentage. You can use my gear range calculator spread sheet to work out your current gear range it also includes some gear range percentages for hub gears.

Gear Range % Cassette vs Hub Gear - Comparison

Gear Ranges of some Hub Gears

Sturmy Archer 3 Speed = 177% Gear Range

Sturmy Archer 5 Speed = 256% Gear Range

Sturmy Archer 8 Speed = 325% Gear Range

SRAM 2 speed            = 136% Gear Range

Nuvinci                         = 360% Gear Range

Rohloff                       =  526% Gear Range

Gear Range of Derallier drive Trains

1 x 9 (11-32)            = 290% Gear Range

1 x9  (11 -34)           = 309% Gear Range

1x10 (11 - 36)          = 327% Gear Range

3x10 (Typical)          = 550% Gear Range

Gear Range % Cassette vs Hub Gear - Summary

Unless you want to spend of fortune on a NuVinci or Rohloff, you will not beet a typical 3 x 9/10 derailleur setup. Good ranges can be had from a 1 x 9 setup which provide simplicity of operation with ranges that better most lower end hub gears.
