Are cassettes better than freewheels?

A freewheel has a lower number of gears so is better suited for casual riders who don’t require the larger selection of gears available from a cassette. It’s much better coasting, allowing you to rest your legs, and if done correctly, can be useful when climbing hills and easier coming down them.

What are 7 speed bikes good for?

A 7-speed bike is a great bike for a person who rides on tricky terrain. It’s main purpose is to let the bike adapt to rough conditions and accommodate inclines, bumps and other difficulties. On a 7-speed bike, the lower gears make it easier to pedal and the higher gears allow for better movement going downhill.

Can I replace a 6 speed freewheel with 7 speed?

6 Speed to 7 Speed If your bike currently has a regular-spaced 6-speed freewheel, you can generally upgrade to 7-speed with little trouble. Since the sprockets are closer together on a 7-speed freewheel, the overall width is only very slightly wider than a regular-spaced 6-speed.

Can I replace a 7 speed freewheel with an 8 speed?

You can change to 8 speed, but a normal rear wheel for roadbikes will not fit directly into the frame because it’s 130 mm wide. Depends on the stiffness of the rear frame if it can be pushed together safely to 130 mm.

What 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.

How do I choose a Shimano 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.

Are there any Shimano 7 speed jump cassettes?

For example, Shimano doesn’t make any true “corncob” (one-tooth-jump) cassettes for time-trialists or flatland riders. In 7 speed, the closest is the J (13/14/15/16/17/19/21). If you remove the 21-tooth sprocket from a J, you can make it into a 13-19 corncob by buying an 18 to put between the 17 and the 19.

Their function is convenience, in allowing the cassette to be installed slightly more easily. To make a custom cassette, you will often need to remove the screws or rivets.
