Started this discussion. Last reply by Terry C on Wednesday. 42 Replies 0 Likes
To assist with climbing & not grinding away up long hill rides considering a move to a compact crankset 50/34. Would including the compact be like adding 1 to 2 lower gears & losing 1 to 2…Continue

"Providing that the chain line is still reasonably straight, this is an efficient combination."
Tim B replied to Troy Aberline's discussion Compact vs Standard Crankset - Differences"I actually use my 52 x 21 quite a bit, (i have a 23, 25, 28 above it) but then I also use my 52 x 11 quite a bit too on the downhills around the place, still spin it out at 125+ rpm, 70-75 kph."
"Another very good reference, though maybe a bit detailed for some is this link to a PDF on bicycle chain / sprocket efficiency. Go to page 5 of the PDF for a simple chart on power loss difference between a 52 x 11 and say a 52 x 21 - - the latter…"
"That is correct. A 50 x 11 or 12 is not as mechanically efficient as say a 54 with something further up the cassette. An 11 tooth sprocket is regarded as on the limit as far as chordal action is concerned.
See explanation…"
Matt Jones replied to Troy Aberline's discussion Compact vs Standard Crankset - Differences"Very interesting point from the Giro commentary, I've often heard the comment, "the pro's run a 54 chainring" ....
One of the commentators mentioned that they run a bigger front chainring to allow them to run a little higher up…"

durian rider replied to Troy Aberline's discussion Compact vs Standard Crankset - Differences"Thats my point Tez. Why do you feel the need to ride harder gears at a lower cadence than even a pro on epo would?
But hey, whatever works for you mate. :)"
"Not on my budget, I make do with a very ordinary mobile phone. ."
"Ignorance on gearing ? I have been riding for more years than you have been on the planet !"
durian rider replied to Troy Aberline's discussion Compact vs Standard Crankset - Differences"Not questioning your fitness Terry. Just your ignorance of the importance of gear selection to ensure more efficient cadence aka better power production for the same given effort.
I know riders that are fitter than me but Im faster than them as I…"
"I don't have any sort of GPS device."
"DR, you are clearly not taking many things into consideration. First of all, 27 kph average on this particular ride is considered well above what most people over 50 could do ! It was actually quite a "cruisey" ride for me on…"
durian rider replied to Troy Aberline's discussion Compact vs Standard Crankset - Differences"Simon Gerrans in this years TDU was riding a bike lighter than your steel beast. Gerrans rode TDU with a 38x28 min gear set up.
Given your low average speed, your are over gearing yourself on the steeper sections. Look at the average speed of…"
