Frequent question: How do I choose a mountain bike cassette?

The rule of thumb for choosing the right bike cassette is that the closer the number of “teeth” from the largest and the smallest cogs, the smaller the variation between gears, which ensures a smooth gear change.

What MTB cassette do I need?

Most MTB bikes use 9- 10- 11- or 12 speed cassettes although more budget models may use 8- or less commonly, 7-speed. A typical gear spread for an MTB cassette (the amount of teeth on the smallest and largest sprockets) would be 11-34t.

What is the difference between a 10 speed and 11 speed cassette?

Tighter spacing on cassettes AND wider range from top to bottom of cassette are possible in the same cassette with 11 vs 10. This can make a pretty big difference when climbing. 4. The 11 speed stuff just shifts better than the comparable line of 10 speed components, it’s actually quite noticeable.

What does an 11 32 cassette mean on a bike?

Numbers denote number of teeth on smallest cog i.e. 11-32 has smallest cog with 11 teeth, and largest with 32 teeth. 11-32 gives you larger range of transmission ratios while 12-25 gives you smoother steps between the speeds.

Is SRAM better than Shimano?

Shimano and SRAM both make quality products, but their approach and styles are different. Looking at the current component landscape, it can be said that Shimano is generally the more conservative of the two. Over the last decade, SRAM has pursued drivetrain innovation more aggressively.

Why are SRAM cassettes so expensive?

The SRAM cassettes are lighter because of the lack of spiders connecting the different cogs, and the smaller driver. That’s why they are so expensive too. and at least the highest end stuff (like eagle, possibly some of the 11spd stuff) is machined from a single piece, and isn’t an assembly component.

Can I replace a 10 speed cassette with an 11 speed?

Luckily, many common and not-so-common wheelsets, as long as they’re at least 10-speed, can be upgraded to 11-speed by purchasing a new cassette body. The body is the part that attaches to the center of the hub and drives the wheel and bike when you pedal.

Can I use an 11 speed derailleur on a 10 speed cassette?

the 10 speed and 11 speed derailleurs are interchangeable as far as the shifters go, the difference is that a 10 speed derailleur doesn’t like a cassette cog much bigger than the 36t it was designed for, where the 11 speed derailleurs are designed for 40 and 42t cogs, and seem to be able to handle bigger.

Will 11 speed cassette work with 10 speed?

It will shift fine with a Shimano or SRAM 11-speed system. And in case any of you were wondering, if you have a 10-speed Shimano or SRAM system and buy a wheelset now, you can still run 10-speed cogs on that wheel. To put a 10-speed cogset on an 11-speed freehub, you just put a spacer behind the largest cog.

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.

Is gear 1 high or low on a bike?

Bikes generally have 1, 3, 18, 21, 24, or 27 speeds. (10- and 15-speeds are obsolete and you don’t see them on new bikes anymore.) Lower numbers are the low gears, and higher numbers are the high gears. First gear is a low gear.

What is the easiest gear on a bike?

The easiest (lowest) gear is when the chain is on the smallest ring in the front and the largest cog in the rear. The rest of the gears range between those two extremes. The bigger chainring is HARDER to pedal and the smaller chainring is EASIER to pedal. The ring(s) in the front are individually called chain rings.

How many miles should a cassette last?

Get at least a 1000 miles out of chain and cassette. Always change both at same time.

Should I replace chain and cassette together?

You should change your chain at the same time as the cassette and/or chainset. “A worn chain on a new cassette or chainrings will only accelerate the wear,” says Chris McKenney.

How often should you change your cassette?

My rule of thumb is to replace it at 75 per cent wear (as measured with a chain-wear indicator). If you stick with this guideline, your cassette and chainrings will last a lot longer. A cassette, in most cases, can last for approximately two to three chain replacements if they are done at the right time.
