Is a 12/25 cassette good for climbing?
The vast majority of road bikes come with a 12-25 cassette, which is suitable for most cycling terrain when paired with a compact or standard chainset. If you ride a lot of hills or struggle with hill climbing, a cassette with a lower ratio largest sprocket (27 or more teeth) may be beneficial.
Does it matter how many teeth on a cassette?
As most bikes come supplied with a cassette with a 25 tooth sprocket as the largest sprocket, if you switch to a cassette with a larger biggest sprocket (somewhere around 28 teeth) it will make a big difference. Bigger than you think. Three little teeth doesn’t sound like much difference but it really is.
What kind of derailleur for a full suspension bike?
A full suspension bike typically needs a higher capacity derailler than indicated by the drivetrain parameters to allow for rear axle movement as through the travel range. I have an older bike that I really like. The bike shop says I should replace my rear derailleur, which is a Shimano RD TY22 WD. I cannot find this derailleur listed anywhere.
What does this mean on a derailleur?
fwiw, SRAm make an apex bar shifter with exact actuation (not X-actuation). THis means you should be able to use a 10 or 9 speed MTB derailleur with a 11 speed cassette on your MTB setup. is not DynaSys on the entry line altus too??
What does the length of your derailleur’s Cage mean?
The length of your derailleur’s cage defines the range, or spread, of gears you can have on your bike – the longer the cage, the more slack in the chain the derailleur can take up. For the sake of simplicity, we have included a quick guide below, but if you’re in any doubt read on to see how we come to these conclusions.
What is the capacity of a Shimano road derailleur?
For the sake of example, let’s assume you are looking at a Shimano road derailleur here. The total capacity of a SS (short cage) Shimano derailleur is 35t and 39t for a GS (medium cage) derailleur.
What is the difference between 11-28 and 11-32 cassette?
In the event you find yourself grinding up a hill at 7 mph, the 11-32 cassette allows you to ride at 81 rpm, while with the 11-28, you’ll be riding at 71 rpm. One final thing to note: The 11-32 cassette needs a longer cage derailleur and a longer chain than the 11-28 cassette.
What is a 12/25 cassette?
A cassette is the collection of sprockets on the hub of the rear wheel. Most road bikes come supplied with a 12–25T cassette, where the smallest sprocket has 12 teeth and the largest sprocked has 25 teeth.
What is the difference between 11-28 and 11 34 cassette?
As shown, the maximum speed is the same with the 11 tooth cog and the 11-28 and 11-30 cassettes share the same gearing combinations until the largest three cogs. However, the 11-34 cassette has easier gearing in every combination except while in the 11 tooth cog.
What size 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 chainring size?
The smaller the chainring, the easier the lowest gear for climbing; the bigger the chainring, the faster you can go in the highest gear. You can calculate the gearing ratio by dividing the teeth of the chainring with the teeth of the cog on the cassette.
What is the best gear ratio for climbing hills?
If you don’t want to stray out too far, a 46/17 to 42/17 are good gear ratios for smaller and occasional hills. These gear rates are considered a good middle ground that can be used in flat and hilly areas.
