Swapping from a double to a triple, or the reverse, is quite an expensive process because you need to change other groupset components too. That said, a triple can be a good idea, especially for something like a touring bike where you need those very small gears to climb while carrying a heavy load. You do get some very small gears with a triple chainset, but there’s a lot of duplication (different chainring/sprocket combinations giving the same, or virtually the same, gears) and most people find a double chainset with a wide-range cassette ample and more convenient to use. Campagnolo offers only Athena in a triple (52, 39 and 30-tooth chainrings) while SRAM doesn’t offer triple chainsets for its road groupsets, although it does for its Via 27 and 24 trekking ranges. In each case the chainrings are 50, 39, and 30-tooth. Shimano offers triple chainsets for its three cheaper road bike groupsets – Claris, Sora and Tiagra.

Options like FSA's Adventure series cranks, Sugino's OS cranks, or the Praxis Works 48/32 cranks give you a slightly lower gear range for those situations.Įxample bike: Genesis CDA 30 Triple chainsetĪ triple chainset is one with three chainrings. You might have blown up, you might have hit a 20% grade or steeper. As soon as you hit seriously hilly terrain, there's going to come a moment when you need the lowest gear you can get. Fat tyres and dirt tracks demand lower gears, especially if you’re carrying anything extra, like clothes and so on for an overnight stay.īut we think they have a place for general riding too.

The gravel/adventure bike movement has been the main driver of sub-compact chainsets. This means that the gears are lower (easier to turn, but they’ll progress you a shorter distance per pedal revolution) than you get with a 53/39 chainset (above) with the same cassette.įor more details on that, see How much difference does a new chainset make? (below).Ĭompact chainsets have become massively popular because they allow you to keep moving up steep hills, albeit sometimes quite slowly, and many people prefer to turn smaller gears at a higher cadence (the number of pedal revolutions per minute) because it puts less stress on the knees. The last bike we tested that came equipped with one was in 2017, so we should probably stop calling it a standard crankset, because it isn't.Įxample bike Tifosi SS26 Aero Compact chainset​Ī compact chainset has a 50-tooth outer chainring and a 34-tooth inner chainring.

The 53/39 chainset is now a rarity outside the professional peloton. SRAM only offers a 53/39 in its Force 22 groupset the high-end Red AXS and Force AXS wireless electronic systems have their own take on gearing with smaller chainrings and a 10-tooth smallest sprocket.

Of the big three groupset manufacturers, Shimano and Campagnolo offer standard chainsets in their higher level road groupsets aimed at pro riders and other racers/serious enthusiasts, but not in their lower end groupsets aimed at more casual riders. Sometimes, though, pros will switch to larger chainrings for time trials or flat races like Paris-Roubaix. This used to be the default option for road bikes and it’s the choice of most racers in the majority of circumstances. Standard chainsetĪ standard chainset (a bit of a strange term these days) has a 53-tooth (or 52-tooth) outer chainring and a 39-tooth inner chainring. Let’s go through the main road systems in turn. However, some bikes come with a triple chainset, meaning that you have three chainrings, and others use a single chainring matched to a wide-range cassette (the group of sprockets that sit at the centre of the back wheel). The larger chainring gives you bigger, harder to turn gears that move you further per pedal revolution – so it's suitable for higher speeds – while the smaller chainring gives you gears that are easier to turn but move you a shorter distance per pedal revolution – so it's suitable for lower speeds, including riding uphill. Most road bikes come with a double chainset, meaning that you have two chainrings. Different chainsets make a big difference to the character of your bike and the way it feels when you ride.Ĭheck out our Beginner’s Guide: Understanding Gears here. The chainset, called a crankset in some parts of the world, is the name given to the chainrings and the crank arms that turn them.
