The gear ratio on a touring bike depends on a number of factors: where you plan to travel, your terrain, your experiences, if you do not have a good choice start with choose from scratch. Choose a gear low enough to climb to the top and have gears high enough so that you can go at high speed and not be blocked by the wind. choose bicycle touring gears how to go with the best effect. Please refer to the knowledge below to choose for your touring!
1. Determine the bike touring gear range and ratio
The best way to be able to determine the chain link drive ratio combined with the cassette track on a bicycle is to check the inch lengths on your gears. They are very easygoing, which is the diameter of the wheel times the size of the front disc, divided by the size of the rear gear. With the obtained parameters you can compare bicycles with wheel sizes and can set the drivetrain. On a touring bike, 18 is the low disc and 113 ”is the large disc.

1.1 How to compare gears between different types of road bicycles
Given that the trio of gear (48-36-24) will be in the 18 ″ to 113 ″ range how does it compare to different drivability on sport bike steering systems.
- Typical types of road bike discs
+ Traditional road bicycle – 53x39t with 11-23t = 44 to 126 ”
+ Semi-compact bicycles – 52x36t with 12-25t = 38 to 114 ″
+ Bicycles with small frame – 50x34t with 12-25t = 33 to 110 “Frame
+ Bicycle with long tray – 50x34t with 11-32t = 28 to 119 ”
+ Road bike with trio – 50x39x30t with 12-27t = 29 to 110 ″
- Typical types of cyclocross discs
Traditional CX-46x36t with 12-30t = 32 to 104 “
CX1 – 38t with 11-36t = 28 to 93 ″
- Typical MTB discs
Single – 32t with 11-40t = 22 to 79 ”
Singles XX1 – 32t with 10-42t = 21 to 89 ″
Pair – 38x24t with 11-36t = 19 to 96 ”
Three – 42x32x24t with 11x36t = 19 to 106 ″
- Control center
Alfine 8s – 38t with 20t = 27 to 84 ”
Alfine 11s – 38t with 20t = 27 to 111 ″
Rohloff 14s – 40t with 16t = 19 to 100 ”
- Recommended gear ratios for touring bike lines
It really depends on where you are riding, the terrain, your experience, and how strong you are. These are the guides we put together for the average racers looking. Gears are suitable for touring vehicles to climb the hills during their travels.
+ Without panniers: 33 to 110 ”
+ Panniers with 5kg: 29 to 110 ″
+ Panniers with 10kg: 25 to 110 ”
+ Panniers with 20kg or more: 20 to 100 ″
+ Off-Road Touring: 18 to 100 ”
Disadvantages of wide range of gears
While a wider range of gears is often a necessity for cycling, it is also important to note that there are greater gaps between each gear than the lower steering system. These gaps are most noticeable on flat terrain as you may be looking for the perfect gear to maintain your pedal speed. The wide drivetrain shouldn’t be a problem for touring cyclists but if you’re on flat terrain you might consider a narrow range rear cassette for easy control. tune your beat.
2.Speed components
2.1 7, 8, 9, 10, 11 speed actuators
Modern transmission uses 10, 11-speed sprockets with front and rear sprocket. Component makers have also gradually phased out the 7.8 and 9-speed powertrains, although spare parts will be available for the time being. Although the 10, 11-speed chain system uses a narrow chain, when in operation they can still prove to be robust and reliable. Keep in mind that an 11-speed steering always requires a wider cassette box on the center by up to 10 speeds so compatibility with older wheels is likely to be an issue.
Another problem with running 10 and 11 speeds on car rides is not that shops around the world have access to these modern moving parts.
2.2 Cranksets touring
Crankset on bike touring always has a wider range of gears on a crankset’s Mountain bike or a road bike. The smallest disc is usually 24t and the largest is 48t with an average gear lag of 36 t. The trip control requires a MTB cage long enough to cover large differences in chain size.
2.3 One, two or three discs
Conventional bicycles typically use a trio of discs on the front crankset although the new crankset and cassette technology allows wide transmission over a large range with singles and double discs. Most MTB crankset will give you enough proportions so you can go up any hill with the panniers.With the single front system you will have to sacrifice some gears high or low compared to the system. 2x, 3x system. With single setups it is best to give the bike a softer touring when riding on relatively flat terrain.
2.4 Cranksets Splined
Some manufacturers such as White Industries attach their discs to cranks with a latch interface rather than using a bolt-on chain. This system allows for different chain configurations a maximum of 24 teeth spacing between the largest and smallest disc (eg 48x24t or 50x26t).
Crankset can expand his range with just two rounds.
- Diameter of Bolt circle (BCD)
This is a bolt measurement used for different types of discs, the MTB disc and the road vehicle disc are incompatible due to the difference between the corresponding BCDs. The disc for traditional road bikes and compact bikes are also incompatible.
- Below are the sizes of the standard BCDs
+104 / 64bcd: MTB 4 arm cranksets
110bcd: Compact and semi-compact with 5-arm cranksets
130bcd: Traditional road bike with 5-arm cranksets
+130 / 74bcd: Bicycle with trio with 5 arm cranksets
135bcd: Campagnolo 5-arm cranksets road bike
2.5 Lower shaft
The console where your crankset attaches is called the lower middle bracket center shaft often referred to as the BBs. BBs screws directly to the BB cover on the bike frame. Old BBs are commonly known as square, this system works well and is commonly available at bike shops around the world.
A latest technology for the bottom frame is the use of compression pressures whereby rings are pressed rather than threaded into the bottom housings. You probably won’t find much on touring bikes, but it’s now very popular on cyclo, mountain bikes and road bikes.
2.6 Bicycle trailer
The rear cassette tweezers were increasingly expanding their range due to the push by the bicycle industry to get rid of the three-disc drive system. The wide rear cassettes often allow touring cars to successfully set up a double disc.
- Trail bikes and mountain bikes
Standard sprockets typically have a top speed of 27t but now have gears up to 32t (you have to use a long-distance roller). MTB cassette cassettes are available from 11 to 32 to 11-36T (need to reverse derailleur MTB long until double and triple setups)
Shimano and SRAM recently carried a cassette with 40t and 42t gears. The wide bands are designed specifically for mountain bikers to run on a single track. Although the SRAM’s chip requires you to have a specific hub with an XD driver, Shimano’s chip will match 11-speed modern hubs.
- 11-speed Cassette Tweezers
A wider range of cassettes is required on your hubs to accommodate 11-speed cassettes. Please proceed to check if your hub is compatible or not when setting up on your bike.
- Modified backboard with a large band
To be able to convert the 10-speed type from 11-36 teeth to 11-40 teeth, some companies have created space by removing one of the smaller aliases (16t or 17t) with a larger one. (40t or 42t) With this new setup the company has demonstrated good performance on single-drive systems.
2.7 Derailleur
Not all gear switches will work with all disks and discs. The length of the deralleur cage has many lengths depending on the type of gear and sprocket you want to use. Any trio system must use derailleur with long cage.
+ Short cage deralleur can accept chutes from 28-30t
+ Deralleur long cage for road bike accepts chucks up to 32t
+ Deralleur long cage mountain bike accepts chucks up to 40t
+ SRAM 1 × 11 Derailleurs: Only recommended for use with cassettes of 10-42t range
2.8 Hub and gearbox inside
Bicycles with inward directional centers generally have a reduced range compared to touring’s crankset with a wide rear axle. The Rohloff hub is the only product that gets close to a 526% jump from smallest to largest disk. Similarly, Shimano’s 8-speed Nexus has 309% range and the 11-speed speed is 411%.
The minimum gear ratio you can use with Shimano’s Hub is 1.9: 1. Therefore, a 26-inch “8-speed bike will have cogs between 26-79” and a 700c bike will decrease down to 27-84 “. A 26-inch “11 speed bike will have cogs from 26-105” and a 700c bike will drop to 27-111 ”.
The minimum gear ratio you can use with the Rohloff hub is 2.5: 1. So on a 26-inch Rohloff bike you can get between 15-95 “and on a 700c bike you will receive 19-102 ”.
- Gear drive gearbox
Gear-drive gearboxes have a huge range (636%), offering both lower and higher gears than a Rohloff hub.
It is becoming increasingly difficult to find high quality spare parts to replace the 7.8.9 speed however if you are on a big adventure in a remote place, it is difficult to find accessories. For replacement and repair you should use a system with 9 speeds for the system bicycle touring disc gear mine . You will then be more likely to be able to find replacement as well as repair accessories.
If you are new to cycling touring who do not have much knowledge about sports bicycles, please consult useful advice from veteran cyclists to get the best trip.
