Can you run 53 34 chainrings?
You can get large outers that will fit on a 110mm BCD compact crankset, so you could have a 53/34 setup in theory (but if you are able to push a 53T, you shouldn’t be needing a 34T to climb!). But yes, you’d be way beyond the specification of the front mech (16T on most Shimano front mechs).
What does the 52 36 MT mean on an Ultegra chainring?
A semi-compact chainset, sometimes called mid-compact or faux pro, has a 52-tooth outer chainring and a 36-tooth inner chainring. This means that the biggest gears aren’t quite as big as those of a 53/39 chainset but they’re not far off, and they’re larger than those of a compact.
Can a 52 34 chainring run?
52-34 will work but the problem is that when on the 34 the chain will start catching on the big ring up front when you are in the two smallest cogs of the cassette, I ran a bike for years like it.
Can you run 53 36 chainrings?
The ramps and pins on the 53 ring are placed to provide a smooth transition from the 39 ring. With a 36 the transition won’t be as smooth, but it will work.
What is an 11 32 cassette?
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). The combination of your selected chainring and cog determine the gear ratio.
What is 50 34t chainset?
Standard Setup Currently, the most common gearing setup on new road bikes is a 50/34 chainset with an 11-28 cassette. This means that the big and small chainring have 50 and 34 teeth, respectively, and the cassette’s smallest cog has 11 teeth and its largest cog has 28 teeth.
Is a 52 36 crankset good?
“With 52/36 and 11-28t, the gear range is increased both up and down the range (compared to 50-34 and 11-25t), while maintaining adequate shifting. “Plus, a 52/36 chainring combination is still mechanically efficient for the front derailleur.”
Is a 52 36 crankset good for climbing?
Basically, the 52/36 will allow 5% higher top-speed before spinning-out compared to the 50/34. (Many say that your aero-tuck and other factors are more important at those speeds anyway.) But on the hills, you’ll find the 36 to be harder to turn than the 34.
What is a 50 34 crankset?
The basics. Standard cranks are often called racing cranksets because they offer the fastest common gearing (bigger chainrings are available but must be bought separately). Compacts have a 50/34 gearing, so losing three teeth on the big ring and five teeth on the little ring compared to a standard.
What is a 53/39 crankset?
Standard cranks have 53/39 gearing, meaning they have a 39-tooth small ring and a 53-tooth big ring. Ring is short for chainring, which is what the front gears are called that are bolted to the cranks. Compact cranksets are preferred for climbing races or for people who like to ride fast but not race.
What’s the difference between a 53 and 39 chainset?
Put another way, if you pedal at 80rpm, you’ll move at 8.7mph. If you have a compact chainset, your smallest gear (34 x 28) is 32in, so quite a bit smaller than that of a 53/39 chainset. That means it’s much easier to turn the cranks.
What’s the difference between 53 and 49 tooth chainrings?
It’s simple logic – the jump between a 53 and a 39 tooth ring is a 14 tooth difference. Between a 50 and 34, the chain has to jump a 16 tooth difference. It’s not much, but it’s there. Should you switch? Your 53×39 setup should be fine unless you feel the gears are too big/hard for the hills you climb regularly.
What do numbers like 53×39 on chainrings mean?
Hi Charlie, The first part of your question is very simple. The numbers on the chainrings simply refer to the number of teeth on each chainring. A standard crankset will have the 53 and 39 tooth rings (obviously the 53 tooth ring is the large one and the 39 tooth one is the small one,) while a compact crankset typically has 50 and 34 tooth rings.
Which is better 50 / 11 or 52 / 12 chainring?
There are tables available which show the gear inches for different sizes of chainring and cassette. Interestingly a 50/11 will provide a longer gear than a 52/12, meaning that a 50 tooth chainring and 11 tooth rear sprocket will be ‘faster’ than a 52 tooth chainring with a 12 tooth rear sprocket.
