SRAM introduced its XD freehub standard when it started rolling out cassettes with a 10-tooth smallest cog. It recently ported this design over to the road with XDR, which also allows the use of 10-tooth cogs, but is slightly wider than the road bike standard. You need to ensure you’re using a compatible rear derailleur if you’re using the 10-52 option, because the previous-generation Eagle mechanical rear derailleur’s cage is slightly too short. Cassettes listed below will fit most Shimano and Shimano-compatible Freehub bodies, with the following exceptions:

In case you're not sure whether your bike has a cassette Freehub or a thread-on freewheel, we have a separate illustrated article explaining how to tell them apart. SRAM also offers just two cassette sizes in its Eagle lineup – 10-50 and 10-52. The 10-52 is the widest-range cassette made by either manufacturer. Although there are currently two options, it’s likely the 10-50 will be phased out in time because it has been superseded by the 10-52. For example, at the lower end of the cassette, you can have as little as a one-tooth jump between the early cogs, and still have the range at the easier end. If you were running a 7- or 8-speed system, for example, in the same range, the jumps would be bigger. Campagnolo 12-speed rear derailleurs can accept up to an 11-32. The only exception is Campagnolo Chorus, which can take up to an 11-34. As of this writing, Harris Cyclery does not sell IRD cassettes, but they are included here for the sake of completeness -- John Allen.

Shimano’s HG freehub design was the most common option for many years. Felix Smith / Immediate Media There are new rear derailleurs on the market that are identifiable as being compatible because they have a ‘520% range’ graphic printed on the derailleur cage. SRAM Eagle AXS rear derailleurs are compatible with the new 10-52 cassettes. Finance is subject to application, financial circumstances and borrowing history.

Proudly designed and hand-finished in the UK, the AirBike UK 10 Speed Cassette 11-32T boasts Hyperglide-style shift ramps for smooth and efficient gear changes. This versatile cassette is designed to replace Shimano and Sram HG splined hub cassettes, fitting MTB, Road, Hybrid and Mountain bikes with ease. SRAM uses some of the same series identifiers for both "road" and "MTB" cassettes. So, if you see a cassette in the list below but don't find it in SRAM's Road listing, look in the MTB listing. Shimano, for example, uses a system it calls Hyperglide, which is engineered to provide smooth shifting. Its latest cassettes have a newer system called Hyperglide+, which Shimano says reduces shifting time by up to a third relative to Hyperglide, and improves shifting performance under power, up and down the cassette.

Cassette materials: steel vs aluminium vs titanium

You may be on a racing team which needs to have all the bicycles equipped the same, for easy parts interchangeability and to match pedaling cadences. For example, SRAM boasts a 520 per cent range with its 10-52t cassettes. How has SRAM arrived at this figure, and how do you work out your gear range percentage? SunRace does not give tooth counts in the 2016-2017 catalog but there are tooth counts in the earlier catalogs. SunRace listed a 12-32 10-speed cassette in the 2013-2014 catalog but did not give tooth counts for it.

This saves weight and, since it isn’t subject to wear from the chain, the carrier is often made of a lighter material – carbon fibre in the case of Dura-Ace cassettes Beyond weight, there’s not much difference in performance between a Dura-Ace 11-28 cassette and one from a Shimano Ultegra or a Shimano 105 groupset, so you can save yourself considerable expense by down-speccing. However, as groupset manufacturers have jumped onto the gravel bandwagon, there are now gravel-specific gearing options available on the market.SRAM eTap AXS rear derailleurs can take up to a 33t for road, and this is denoted by the ‘Max 33t’ written on the inside of the derailleur cage. There is also a ‘Max 36t’ option to pair with the 10-36 cassette, as well as an XPLR rear derailleur, which can take up to a 44t. Grayed-out rows in the table below indicate cassettes not listed in the 2015 new-products listing or 2016-2017 catalog. SunRace appears at this time to be specializing in MTB cassettes, at least among the 10-speeds. SRAM’s eTap AXS XPLR groupsets are designed specifically for gravel riding. SRAM XPLR cassettes have a range of 10-44 and require their own compatible rear derailleur. It is also possible to mix and match drop bar shifters with mountain bike Eagle eTap AXS components if you want an especially wide-range 1x build. SRAM dubs this a ‘mullet’ setup. IRD has many combinations that are different from Shimano's. Some combinations are rather nice, and others have some uneven steps. The cage of a rear derailleur is designed for a certain range of gears. For example, Shimano’s outgoing Dura-Ace R9100-SS rear derailleur is designed for use up to an 11-30 cassette.

Some people may wish to use a road bike cassette on a mountain bike or vice versa. Here, we’ll go over why you may (or may not) choose to do so, and look at the compatibility issues both options may present. For mountain bikes, 12-speed cassettes are largely the default for higher-spec groupsets, paired with a single-ring chainset. The AirBike UK 10 Speed Cassette 11-32T is an exceptional and economical alternative to mainstream brands, specifically designed to meet the needs of cyclists looking to repair or upgrade their bike. This high-quality cassette is compatible with both Shimano Cassette 10 Speed and 10 Speed Shimano Cassette systems, as well as Sram. It would have been uncommon to find a cassette as large as SRAM’s Eagle 10-50 a few years ago. Alex Evans The most common system is the Shimano 11-speed HG-style freehub, which has 9 splines. Most Shimano groupsets up to the 11-speed era used this style of freehub. SRAM groupsets prior to the current generation of 12-speed groupsets also used the same freehub design, although there are a handful of exceptions with the larger cassette ratios on their 1×11 groupsets.As of this writing, Harris Cyclery does not sell SunRace cassettes. They are included here for the sake of completeness. If you are specifically using a Shimano HG freehub, you need to consider how wide the cassette you are buying is. Road wheels have slightly wider freehubs than MTB ones – by 1.85mm – and 11-speed Shimano HG road cassettes are slightly wider than 8- or 9-speed ones, again by 1.85mm.
