What is the difference between 11-28 and 11-32 cassette?
In the event you find yourself grinding up a hill at 7 mph, the 11-32 cassette allows you to ride at 81 rpm, while with the 11-28, you’ll be riding at 71 rpm. One final thing to note: The 11-32 cassette needs a longer cage derailleur and a longer chain than the 11-28 cassette.
Is a 12/25 cassette good for climbing?
The vast majority of road bikes come with a 12-25 cassette, which is suitable for most cycling terrain when paired with a compact or standard chainset. If you ride a lot of hills or struggle with hill climbing, a cassette with a lower ratio largest sprocket (27 or more teeth) may be beneficial.
What is 50 34t chainset?
Standard Setup Currently, the most common gearing setup on new road bikes is a 50/34 chainset with an 11-28 cassette. 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.
What size cassette do pros use?
Pros often use a 55×11-tooth high gear for time trials. On flat or rolling stages they might have 53/39T chainrings with an 11-21T cassette. In moderate mountains they switch to a large cog of 23T or 25T. These days, they’ve joined the big-gear revolution like many recreational riders.
Why do I need an 11 tooth cassette?
For example, take a look at this table, showing cruising 1 speeds for a 11- 21 tooth cassette: And compare to this table for a 12 – 25 tooth cassette: You can see that the 11 tooth cog is only really useful for cruising speeds that riders at the professional level can maintain, or for short bursts.
Where does the 11 cog go on a cassette?
The 11 cog does not actually go onto the splines like the other cogs. It sits on the end of the hub, and partially goes onto the shortened splines. It requires a special variant of the lock-ring, which comes with the cassette.
Is it worth it to change cassette from 12-25 to 11-28?
I went from a 53/39 12-25 to a 53/39 11-28 on an 8 speed transmission and the gear ratios are fine, the 28t does help a lot but it won’t be that big a difference to suddenly start doing hills you couldn’t before with ease. Worth getting if you are struggling with hills and you also have to option of swapping back to the 12-25t later.
Can a 11-25 cassette be used as a small ring?
Therefore, with a 11-25 cassette, you can ride on “small-ring”/12 rather than “small-ring”/13 like you can on a 12-25 cassette (regardless of whether the “small ring” is 34, 39 or anything else). In the same time, the 11 cog is not useless either as it can be used in downhills or sprints.
