## What is an 11 speed bike

The latest road groupsets are now 11-speed, meaning the **rear cassette has 11 sprockets**. Experienced riders will change gear frequently to maintain a high cadence. Avoid 'cross-chaining', which means using a small/small or big/big combination, as this puts additional stress on components.

## When did Shimano introduce 11 speed

The product was introduced to the market in **2010**. It comprises four stepped planetary series offering up to 11 speeds.

## Are Shimano cassettes interchangeable

SRAM and Shimano cassettes, on either road or mountain bike, are **interchangeable with each other** as the spacing is the same between the sprockets.

## Can I put a 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**.

## How do I know if my bike is 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.

## What is the difference between a 10 speed and 11 speed bike

**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.

## Are all Shimano 105 11 speed

Shimano has launched a brand new version of its 105 groupset – the most popular road groupset worldwide – that features an **11-speed drivetrain** and, says Shimano, improved braking power. The new 5800 series 105 features technology that has trickled down from Shimano's high-level Dura-Ace and Ultegra groups.

## When did Shimano SIS come out

1984Apart from indexed shifting (Shimano SIS), which arrived in **1984**, where the lever clicked between gears eliminating the need to 'feel' the chain on the sprockets, there had been no real innovation in this area. Being in the right gear at the right time was simply one of the skills that had to be learned and practised.

## Can you mix and match Shimano components

It is **possible to mix and match as long as you get components from the same generation**. For example: 9000 Dura Ace, 6800 Ultegra, and 5800 105 are all cross compatible. Each have 11-speeds in the rear, use the same cable pull per shift and use the same front derailleur design.

## Are all Shimano 11 speed cassettes interchangeable

When SRAM entered the road groupset market in 2006, it decided to adopt Shimano's specifications for its chains and cassettes. As a result, the chains and cassettes from the two **brands have always been completely interchangeable for any given type of transmission** (e.g. 11-speed).
