Sep 28, - The gear ratios you want to use for a hilly cycling holiday in Mallorca The gears on the rear wheel are called 'cogs' and when you put a People who actually ride bikes only refer to the number of cogs in the cassette, so an 8 speed, a 9 The combination of your selected chainring and cog determine the.
Front widths on mountain bikes are either or Cassette size, you need a hub unless using a free wheel that is spaced for the cassette you'll be using. A 7 speed cassette will fit an 8 speed hub with a miuntain.
Cassette type, shimano and sram require a compatible hub, campy requires a different compatible hub. Brake type, rim brakes need a specific rim, disc brakes and coaster brakes require a specific hub.
Axle diameter, on Mountain bikes there's 9mm QR and 15mm and 20mm thru axle on the front and 10mm QR, 10mm bolt up or 12mm thru axle on the rear. If you have 8 cogs 8 speed you 26 mountain bike rear wheel 8 speed have to make sure what ratio you want, the smallest being 11 up to 32 largest cog closest to the wheel spoke there's many ratios you can choose from depending on ride style.
If you go anywhere larger than 28, you may need a midsize derailleur If you swap a low speed cassette for higher gears, then you probably can't use same chain as it will be too tight or too loose. Just something to keep in mind: Home Questions Tags Users Unanswered. pep boys dirt bikes
What do I need to know about fitting new 26 mountain bike rear wheel 8 speed on a bike? Ask Question. I know that the new wheels need to be C's, and that the new rear gear cassette needs to be 7-speed I guess because that's what whsel gear shifters are but I have the following questions: Will any C wheel work with any gear cassette? The first question aside, grow and go bike any cassette screw on to speec mounting on the wheel I buy, or are there different threads?

Let us take for an example a drivetrain with front chainrings combination, and a 6 speed cassette. The exact same gear ratio can be achieved with a combination, as well as with Still, in both those combinations, the chain is mongoose ace bike crossed, twisted, like 26 mountain bike rear wheel 8 speed in the picture below:.
This should be kept in mind when selecting gears. Why is this useful? First it needs to be noted that shifting from one front chainring to another requires a bit more time and is harder to achieve if a chain is under pedalling load.
Omuntain, one front shift results in a great er change of gear ratio than a rear shift.
It can in fact be said that front chainrings provide a wider gear ratio range, while rear sprockets provide differences in gear hweel of adjacent gears. Imagine riding on a flat, approaching a hill.
Say the chainrings on the bike are and the cassette is a 9 speed one: For a decent pace on the flat, one could use aor a combination. They both give almost identical gear ratio, without much biie chaining. However, once a climb starts, a lower gear ratio will citizen bike gotham 7 necessary.
However, if one approaches the hill with a combination, lots of gear range change is achieved by gradual and easier rear shifting. Why can this be awkward?
Mounain, as one starts to climb, a large front shift is necessary.
Gear ratio change after shifting from big to the small chainring is so large, that it requires at least two more shifts on the rear to achieve a similar a bit shorter whee ratio. In practise it looks like this:.
After combination, shifting toor even is required in order to not make a gear ratio change too large. This can be useful on terrain that has lots of short steep climbs and downhills i. Parking Sensors. Fitness Technology. Great Offers in Technology.
