Is a 30t chainring good? This is good for riders who struggle with climbing, regularly ride steep terrain, or carry extra weight with bike bags. On a mountain bike, the small change of swapping from a 32t to a 30t chainring gives you gearing that is 6.7% easier. For gravel, going from a 42t to a 40t provides 5% easier gearing.
How big should my chainring be?
Typical gearing for a standard double is 53t-39t which offers big enough gears for competition usage. Then there is the compact double which gives the same number of gears (2×10 or 2×11) but smaller chainrings meaning lower gearing options for leisure and sportive riding. A typical compact setup is 50t-34t.
Is a bigger chainring faster?
A higher/bigger gear will not make you go faster. (Before going any further, the basics of gearing are that the larger the front chainring, the higher the gear. For the rear, the smaller it is, the higher.)
What does 32T chainring mean?
T is the number of teeth on a sprocket or chain ring. Your lowest gear would be with 32T at the rear and the smallest number of teeth at the front chain ring. Conversely, the smallest at the back and largest in the front gives you your highest gear.
What is an 11 32 cassette?
That means the outer ring has 50 teeth and the inner ring has 34 teeth. The rear cassette is 11 speed 11-32. This means there are 11 cogs ranging from 11 teeth up to 32 teeth (the exact cogs are 11/12/13/14/16/18/20/22/25/28/32).

Is it harder to pedal with bigger chainring?
The bigger chainring is HARDER to pedal and the smaller chainring is EASIER to pedal. The ring(s) in the front are individually called chain rings. Geared bicycles come with one, two or three rings (notated as 1x, 2x and 3x) and together the set of chain rings is called a crankset.
What size chainring 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.
What gear ratio is best for climbing?

Is 1x better than 2x?

What tooth oval chainring should I get?
Which size of an oval should I choose? We always recommend swapping like for like, so if you have a 32T round ring at the moment, you should consider getting a 32T oval. The same applies to our shiftable road ovals, we recommend that you purchase ovals with the same teeth count as your round rings.
Why are oval chainrings better?
Oval chainrings maximize the part of the stroke where power is produced and minimize resistance where it isn't. As a direct consequence, Oval rings enhance a cyclist's ability to spin with a smoother power delivery and feel much easier on legs while climbing. Meaning you will go faster and get less tired.
Are absolute black chainrings worth it?
Aesthetics aside, I really like the absoluteBlack chainrings – the shifting is really good, and the benefits of the lower gearing and smooth pedalling style they produce works really well on gravel. It's an investment, but one that is worthwhile.
What is the difference between 110 BCD and 130 BCD?
BCD stands for Bolt Circle Diameter. It is the distance from side to side of a circle that goes directly through each bolt hole in a crankset. The diameter of that circle is the BCD. When you see a measurement like 110 or 130 BCD, that means that diameter is 110 or 130 millimeters, respectively.

Changing rings is not that difficult, and in some cases, it's possible to replace chainrings without removing the crank. That possibility is limited by what ring sizes you're using, but hey, it's always nice when you can work smarter not harder. This trick works for most road cranks and some mountain cranks.
What is the best chainring size for MTB?
Broadly speaking, if you ride a 29er and/or ride in steep mountains go for a chainring with 32T or fewer (the 11 speed Sram XX system goes down to 28T if your bike has the XX drivetrain). If you ride 26″ or 27.5″ wheels and/or ride in less mountainous terrain then go for a 34T or possibly even 36T chainring.
Do I need to change chain when changing chainring size?
If you ring changes by 2 teeth, the chain only sees a 1 tooth difference. You can only change the chain in 2 tooth increments and almost always you can change a ring by 2 teeth and not need to change the chain length. Of course you should always check.
Which sprocket is faster?
You can gear up by using a smaller rear sprocket or a larger countershaft/front sprocket. Gearing up adds more speed and decreases the final drive ratio. You can gear down by using a larger rear sprocket or a smaller front sprocket. Gearing down reduces speed and increases the final drive ratio.
Which gear is hardest to pedal?

How do I choose gear ratio?
The conventional procedure for selecting gear ratios is to pick ratios that run the engine rpm to redline at the end of the medium and longest straights, and pick the lower gear ratios to minimize the rev drop at each shift. This method minimizes the number of shifts per lap.
