Is there another sub-compact crankset compatible with Shimano 24mm spindles?

Probably yes but you're committing to buying two cassettes each time you replace chain/sprockets. Last week we replaced a 34x50 Campagnolo crank with the new IRD Super Compact 30x46 (w/ 11~32 cassette) which worked out well; happy rider. Many paths to victory. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 Here's the 14 problem: with a strong tailwind I could only ride at 28 mph with a 13. On downhills you can easily exceed that speed and not being able to pedal limits your control. I really don't know what you mean by "wide ratios" since I have an 11-28 and with a normal compact crankset since that the lower gears are too close together - 11-12-13-15-17-19-21-23-25-28. On the lower gears you WANT wider ratios so that you can actually feel a change in the necessary strength required to pedal. I'm climbing 9% hills in the 21 and 23. And the 21 gets easy as the grade flattens out a bit. On a local 6% climb I'm in the 17 or 19 and the group is running away from me in their higher gears. So I think that you ought to consider your own training rather than making odd choices of gearing. They don't make these expensive cassettes because the manufacturers are stupid. I think the OP knows best what gearing he needs. Among my riding buddy's climbing longer ( 3-4 km) 9% stretches in 34-21 or 34-23 is very unusual.. I use a 11-32 cassette in the mountains: 11-12-13-14-15-17-19-22-25-28-32.. I would trade in the 11 and 12 for a 18 and a 30 in an eye blink. 11-12-13-14-15, WTF? On the flats I ride a 12-25 cassette; 12-13-14-15-16-17-18-19-21-23-25. I would trade in the 12 for a 28 so I could ride that cassette in the hills in my backyard which are not longer than 2 km with grades up to 15% for a couple of 100 meters. YMMV. Lou you weakling! You need to do more training. NOBODY should ride any cog larger than a 23t -- with a 49t front ring, like Jobst Brandt the human diesel truck. Personally, I ride 11sp: 11,11,11,11,12,12,12,12,13,13,14 (bail out gear) with a 50/53 compact. I ride 17% grades both ways to work and climb all weekend. Yeah, I'm weak but the funny thing is that I ended up in the upper half of the all time Strava ranking on all climbs I did during my Tour through the Alpes this year and that with my 11-32 cassette and my age of 61 years. Unbelievable. One of my riding buddy did the same mountains on a 11-25 cassette though but he was an exception. Lou |

Actually, I did a 17% descent on the way to work this morning, and contrary to TK's assertions, the fact that I spun out and quit pedaling did not reduce my control. My control was reduced because I was airborne over bad pavement. This hill, except going down: https://www.youtube.com/watch?v=HsaGtzCbSmc (****ty video, hill starts at about 1:00) I usually climb that in my low gear of 50/14, spinning like Chris Froome. Really, I'm that strong. Say hey to Tom Dumoulin if you see him, and remind him of our ride this weekend. We were going to do some hill repeats on Monte Zoncolan. Everyone who's actually fast rides Record 12 speed: http://www.yellowjersey.org/photosfr...t/2018ca12.jpg -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 Look at the cassettes they offer: Model Index: 11-29: Gradation: 11-12-13-14-15-16-17-19-21-23-26-29 t Factory Number: CS19-SR1219 11-32: Gradation: 11-12-13-14-15-16-17-19-22-25-28-32 t Factory Number: CS19-SR1212 They keep insisting using the 11t and still don't get understand the needs for the 'normal' people. The super compact cranks come for a reason. Lou |

Thanks in advance Dimitris No reason why it shouldn't work. I've done the same with less expensive cogsets. I've had no problem with the cassette locking ring coming loose even though it butts against a non-serrated cog. Cheers |

A bike with 48x12 high, another with 44x11 high, and another with 52x13. All three are slightly, slightly, slightly under geared. The 44x11 is my touring bike. When riding it unloaded, with a tailwind, and downhill a bit, I can and do spin out a little too soon. It needs just a bit higher gear. Maybe a 45x11 or even a 46x11 high gear. A 4:1 high gear is just not quite high enough. Close, but I want/need just a bit higher high gear. A 50x12 high gear would be near perfect. |

Probably a straighter chainline and not on a lousy running 11t sprocket. I know but what I meant was if I’m on the small ring doing rollers it’s because they’re a bit steep so when I top one I can stay in the same ring by going to the 11. Otherwise I’m probably not using 36/11. -- duane |
