Your standard racing bike (triathlon or road) has **10 gears** attached to the rear wheel, collectively known as the cassette. Each one of those gears is a cog. Up front, attached to your cranks, are the gears we call the chain rings.

## Which cassette ratio is best for climbing?

For hill climbing and mountainous terrain, we recommend a road cassette such as the 11-32T SRAM Red 22 XG1190 11 Speed Cassette (A2), or the 11-34T Shimano Ultegra R8000 11 Speed Cassette.

## Can you do a triathlon on a single speed bike?

Subject: RE: Singlespeed bike for sprint tri? I’ve got a fixie and at some point will ride it in a triathlon. You wouldn’t really have any additional disadvantage over a geared bike that you don’t already have (you’ll spin it out going down hills and have to grind going up).

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

10 speed chains are slightly different from 11 speed. 10 speed chainrings are slightly different from 11 speed, but in most cases, you can simply swap out the chainrings instead of buying a whole new crankset. Some rear hub cassette bodies are only designed to accomodate up to a 10 speed cassette.

## How do I choose a cassette ratio?

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.

## Can you put an 11 speed cassette on a 10 speed bike?

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 gearing does Chris Froome use?

Gearing consisted of 52/38 chainrings, and an 11-28 cassette, which he turned at an average cadence of 97rpm. Using this information, and some complicated maths, we can estimate that Froome spent most of his time using a 38×21 gear ratio.

## Can you use a fixed gear bike in a triathlon?

you won’t be granted a competitive advantage with the fixed gear but you’ ll be able to finish the race just fine! If you really want to be safe, use the freewheel side of the flip flop hub and then you’ll be just like every other bike out there.

## Is 10 or 11 speed better?

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.

## How do I know if I have 10 or 11 speed?

Multiply the front gear number by the rear gear number to get the number of speeds. For example, if you have two front gears and five back gears, you have a 10-speed bike.

## Can I use an 11 speed chain on a 12 speed cassette?

An 11- speed chain will cause chain rubbing and poor shifting when used on a 12-speed cassette because of the extra width. If your goal is optimal shifting, it’s recommended to avoid this combination. Also, an 11-speed chain will accelerate component wear due to the stress on the drivetrain.

## What is an 11 32 cassette?

That means the outer ring has 50 teeth and the inner ring has 34 teeth. The rear cassette is 11 speed 11-32. This means there are 11 cogs ranging from 11 teeth up to 32 teeth (the exact cogs are 11/12/13/14/16/18/20/22/25/28/32).

## Can I change a 9 speed cassette to 11?

Converting a 9-speed wheel to 11-speed You will have to buy a new 11-speed wheel and replace the entire wheel. On the other hand, if your current wheel is an 11-speed wheel, you can convert it to 11-speed by removing the low spacer from the low side of the 9-speed sprocket and installing an 11-speed sprocket.

## How many speeds should a road bike have?

A road bike will have either a triple, double or compact crankset. This refers to the number and size of chainrings (located by the pedals). A triple crankset has 3 chainrings; it is often paired with a 9-speed cassette on the rear wheel to give it a total of 27 gears.
