EZRider Posted August 8, 2013 Posted August 8, 2013 WTFisa "WIFLI" ? It's a rear derraileur capable of accommodating a 32 rear cassette.Originally designed for beginners who wanted to move to a double crankset and keep a wide gear range it was used by some world tour riders on the Vuelta and Giro where keeping high cadence on the climbs is difficult.SRAM now make a RED version because of this.
EZRider Posted August 8, 2013 Posted August 8, 2013 What is different with a compact crank besides the number of teeth on the chainrings? Smaller BCD? Yes but some new cranks can handle both ranges.
javadude Posted August 8, 2013 Posted August 8, 2013 A "compact" crank doesn't instantly make you a better climber. That is true, but it can make the difference between getting up the hill and not getting up the hill. My compact made the Argus a real pleasure. I just spun up the hills in my 34/26, and I wasn't all that fit.
Jacques999 Posted August 8, 2013 Posted August 8, 2013 Just a logic check chaps...the actual number of teeth front and back don't matter - it's the ratio of the two that matters. 53/12 and 50/11 is only about 3% different (effectively the same thing). In a blind test I nobody would feel the difference. A "compact" crank doesn't instantly make you a better climber. Likewise - 39/21 and 36/19 is identical. There are only two ways to make it easier on yourself on the climbs (and by easier I mean pedal faster at exactly the same speed - you will not go faster):1) Less teeth on the inner front.2) More teeth on the inner back. The easiest way to make it easier is more on the inner back - buy a cassette with a 25 or 27. Much cheaper than a new crankset.
Chopper Jr Posted August 9, 2013 Posted August 9, 2013 whats your cadance at 60kph on a 50/11? Ja, just over a hundred...
T-Bob Posted August 9, 2013 Author Posted August 9, 2013 Hit a few hills today in the UK on a compact with a 28 on the back. One climb was 27% and i was happy with every extra tooth on the back! With the Cape Cobra coming might just bring one back.
Bianchisti Posted November 21, 2013 Posted November 21, 2013 Anyone know what the percentage difference between 39/27 and 34/25 would be?
Bianchisti Posted November 21, 2013 Posted November 21, 2013 Or maybe. Does 1.4 for both sound about right? (Apparently it's exactly the same according to my quick Internet research?.(
cadenceblur Posted November 21, 2013 Posted November 21, 2013 Have you checked the Sheldon brown site? Nice comparison chart, iftthat's whatyyou're looking for.
gummibear Posted November 21, 2013 Posted November 21, 2013 BothA 36/50 with 11-25 on one bike and a 39/53 with 12-28 on the other.
