I'm reading that the calculations are off by double. No there not, you count outter links( every other one) . I use this app off line and don't get ad interference. My opinion is 5 stars all day long.
Not accurate. Was told 112 links, so I reduced my brand new chain from 126 to 112. Guess what? Rear mech isn't clearing the 10th cog on the cassette, because the chain is too short.
simple, easy and fast way to calculate ratios and speed for a given cadence. thank you guys!
Calculation is incorrect. Off by 50% at least. The bicycle in question is a Specialized Ruby. The chains Tay is 416mm. Largest chain ring is 50. Largest sprocket is 32. The stock chain is 108 links. When attempting to calculate the chain required for a 36 tooth sprocket, this app says 55. The standard length of a chain at retail is 116 links.
You have to double the given value otherwise it's not even close to the correct chain length.
Very intuitive. Has most (if not all) the parameters you may need.
Size in centimeters is good, you have to divide it by 1/2" to get number of links. 1/2" is 1.27 cm.
Calculated chain length is at least half of what it should be.
Not even close to the needed links
The result should be double.
Unusable with ads and incorrect measurements. Each time I amend the data input, I get an ad. Once I was finally at the end, the calculation was 4 links out from optimal size required.
