That means the outer ring has 50 teeth and the inner ring has 34 teeth. The rear cassette is 11 speed The combination of your selected chainring and cog determine the gear ratio. The gear ratio, combined with the circumference of your wheel and tyre determines how far you will travel with each revolution of the cranks.
To get our gear ratio we divide the number of teeth on the front by the number on the back:. This is expressed as 4. This is the gear I would use on the flat. It is going to take quite a lot of effort to get it moving, but when I do I will move quickly. This would be the opposite end, the small ring on the front and the biggest on the back. The reason for this is that they are the closest together, meaning you get a really low ratio. On the bike I ride this is 34 teeth at the front and 32 at the back — so really close.
This would be the gear I am using on the very toughest of climbs allowing mean to spin the wheels quickly to get my cadence high. There's two buttons behind the brake lever on each shifter. On the left the slimmer dimpled inside button will shift the chain up from the small ring to the big ring. The smooth paddle-shaped outer button below will move the chain down from the big ring to the small outer ring.
On the right shifter, the inner dimpled button will move the chain up the cassette to easier gears, while the smooth outer button will move the chain towards the harder gears if you're riding faster. Like its mechanical cousin, Campagnolo Super Record EPS shifters feature a button behind the brake lever and a thumb button inside the shifter hood. On the right-hand shifter the button behind the brake lever will move the chain up the cassette into an easier gear. The thumb button will do the opposite and move the chain into a harder gear at the rear.
EPS also offers multi-shift, so if you hold the button down the chain will shift multiple gears until you release the button. On the left-hand shifter, the paddle button behind the lever will move the chain from the inner small ring to the larger outer ring.
The left-hand thumb button will do vice versa. The right-hand paddle button, behind the brake lever, moves the chain into a harder gear on the cassette. The left-hand paddle button moves the chain up the cassette into an easier gear.
To move the chain between the two front chainrings, the rider simply needs to push both the left-hand button and right-hand button at the same time and the chain will move up or down depending on its starting position. Chainring: toothed ring at the front end of the drivetrain, attached to the crank. Cassette: cluster of sprockets at the rear of the drivetrain, containing up to 12 gears, of various sizes. Block: another term for the group of rear sprockets, but really refers to the older, screw-on freewheel.
Derailleurs: front and rear derailleurs do all the hard work of moving the chain from one sprocket or chainring to the next. Drivetrain: term grouping together all the moving parts that connect the crank to the rear wheel and hence drive a bicycle along — namely the chain, the cassette and the chainrings.
You get a bigger change when you shift with the left-hand shifter than when you shift with the right-hand shifter. The solution?
Downshift to first gear. How does that solve the problem? First gear moves you a shorter distance for each spin of the pedals, which makes it easier to pedal. Click HERE to check it out.
If you need a small change, use the right one. Try to keep the chain in a sort-of straight line between the front and rear sets, rather than going at an extreme angle from left to right. For example, in the very lowest gear, the chain will be all the way on the left on both sets. In the very highest gear, the chain will be all the way on the right. That stretches the chain and wears it out.
Instead, shift the front set from the left to the middle 1 to 2. That keeps your chain nice and straight. Play around with shifting, and see how it feels to ride in different gears. Typically, the left-hand shifter changes the front bike gears, and the one on the right controls gears in back. Different brands of shifters all function slightly differently, but all shifters are pretty intuitive. Consult your bike shop at the time of purchase on how yours work or simply jump on your bike, make sure to pedal, and push your shifters to get a sense of how they function.
Most geared bikes have one, two, or three chainrings in the front the rings attached to the pedal crank arm and anywhere from seven to 12 gears—or cogs—in the back or the cassette attached to the rear wheel. Moving the chain from the smallest rear cog to the largest eases your pedaling effort incrementally.
Moving it between the chainrings in the front results in a more noticeable change— pedaling feels easier in a smaller chainring and harder in a bigger one.
The best way to get a hang of what your bike gears feel like is to take your bike to a safe place away from traffic, like an empty parking lot, and shift through all the gears in the front and rear to understand how they feel while riding.
Cyclists spend most of their time shifting the rear gears to find their cadence sweet spot. Use a harder gear on flats or if the wind is blowing from behind a tailwind. When in doubt, shift before the terrain changes, especially on hills.
