Shimano Tiagra 4700 10 Speed Cassette Cycling Equipment

Product Information

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. Knowing when to switch and how to stay balanced during the switch only makes climbing with the 11-34 cassette better. 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. 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.

Terms & Conditions Apply. we need to be clear what we mean when we write 'gears': do we mean cog and chainring teeth (11-12-13 &c and 52-39 &c)? Cog & chainring combinations (52x13)? 11sp vs 10sp? Gear sequence (1st to 22nd)? Gear relationship (higher/lower; highest/lowest)? Cog number on cassette (1-11)? Gear ratios (1:1, 2.74:1)? Gear inches (30–135")? Metres development (4.56)? 'Gain'? Speed at rpm? Or the whole system (derailleurs, chain, cassette, [internal hub] chainrings)? As mentioned above...I'm running a 50/34 10 speed with 11-32 cassette but would like to change to a configuration that would make climbing hill easier.

Both sets of cogs are metallic and made from steel precisely. The last set of cogs, or the largest trio, is in sizes 24, 27, and 30, made of steel with spider aluminum plating.

It’s important to note that this figure is only indicative of the range of gears you have on your cassette, and is not the same as working out how far you will travel with your chosen gear ratio.If you have the 11-30 cassette and intend to climb, upgrading to the 11-34 cassette would be better, as that is the best option for climbing. Please be aware that depending on your specific hub and set up, you may require a spacer for the 11 speed 11-34 cassette to function smoothly. This may be a 0.5mm, 1mm or 1.85mm spacer, available in store.

This shows how far you can push the envelope. I have even run 11-36 using a derailleur hanger extender and nothing suffers except bigger gaps in gears. Longevity of components is not compromised and chain cassette combo is still fresh after 3500 miles. Well, the smallest cog is a 10-tooth, and the largest cog is 52-tooth, which is 520 per cent larger than the 10-tooth cog, thus giving a 520 per cent range. The 11-30 is a good option as a road bike cassette but not the best for hills or mountains. What Size Cassette Do Pros Use; 11-30 or 11-34?

With enough knowledge and a perfect understanding of these two cassettes, many pros prefer to use the 11-34 cassette. If you wanted to use an 11-34 cassette, as well as buying the relevant cassette, you would need to buy a compatible rear derailleur. In this example, it would be an Ultegra R8050-GS or 105 R7000-GS rear derailleur. The GS denotes that these are ‘medium cage’ derailleurs. The same rule applies to Shimano Di2 derailleurs. It is also good for climbing, but the 11-34 is much preferable. The 11-34 is a good option because it will give you the easiest gear, which makes pedaling easier and thus, aids your climbing. An 11-30 cassette is a modern-age product with very good features and serves primarily as a road bike cassette. Shimano only goes to 11-34 with its 105 components, but there are reports of people getting SRAM 11-36 cassettes to work in Shimano systems.
