The chart below compares two gearing setups using 53/39 and 50/34 chainsets with the same 11-28 cassette.Īs shown, chainring size has a large effect on speed. So, for example, if your bike has a 53/39 chainset and a 11-30 cassette, your easiest gear, 39-30, has a speed of 15.0 km/h at 90 rpm compared to a speed of 13.2 km/h with a compact chainset and the same cassette. All of these sizes are compatible with the same cassette and derailleur combinations. Shimano chainsets currently come in three chainring configurations: 50/34 (compact), 52/36 (mid compact), or 53/39 (standard). You may need to change your derailleur to get the range you want.Īnother factor to consider is the size of your chainrings. Older systems generally have lower capacities and it’s best to check with us if you’re not sure what your derailleur can handle. Current 11 speed SS derailleurs can handle up to a 30t cog, while GS derailleurs can handle up to a 34t cog. Shimano road bike rear derailleurs have two possible derailleur cage lengths: short cage (SS) or long cage (GS). The largest cassette your bike can handle depends on your rear derailleur cage length. However, the 11-34 cassette has easier gearing in every combination except while in the 11 tooth cog. The chart below shows the speeds of each gear combination using Shimano 11-28, 11-30, and 11-34 cassette with a 50-34 chainset.Īs shown, the maximum speed is the same with the 11 tooth cog and the 11-28 and 11-30 cassettes share the same gearing combinations until the largest three cogs. These cassettes have the same 11 tooth small cog, so maximum speed is not affected. Switching the cassette to an 11-30 decreases the speed from 14.1 to 13.2 km/h and switching to an 11-34 decreases it to 11.6 km/h. However, what if you can’t sustain 14.1 km/h while climbing and you don’t want to drop your cadence too much? In that case, the easiest change to make is to swap your cassette to one with larger cogs. This setup has a good range in which the shortest (easiest) gear combination, 34-28, has a speed of 14.1 km/h at a cadence of 90 rpm and the tallest (hardest) combination, 50-11, has a speed of 52.8 km/h. This means that the big and small chainring have 50 and 34 teeth, respectively, and the cassette’s smallest cog has 11 teeth and its largest cog has 28 teeth. For ease of understanding, the units for a particular gear will be in km/h at 90rpm cadence on a 700x28 tyre rather than gear ratio or gear inches.Ĭurrently, the most common gearing setup on new road bikes is a 50/34 chainset with an 11-28 cassette.

It will also discuss the effect of the number of gears on a bike. This post will describe the advantages and limitations of different gearing setups including the maximum possible range for Shimano equipment. With hilly events like the Wicklow 200 and the Ring of Kerry, easier gearing is a great way to save your legs and not wear yourself out too fast. There are a few reasons to change gearing, but most customers want to make it easier to pedal up hills in relative comfort (i.e. Recently, a lot of customers have been asking about changing the gearing on their road bikes. This post examines the effects caused by the size of a bike's cassette and chainrings, as well as the number of gears on the bike.
