recumbent fit?
Hi all,
Have recently changed from an upright bike to a recumbent - what is the rule of thumb (rule of thigh?) for setting the seat-to-pedal distance? Thanks, Kerry |

Thanks, Kerry Heels flat on the pedals with your legs fully extended, or about a 20° minimum knee bend when pedaling. Make sure you are fully back in the seat when doing so. You may also want to consider shorter than normal cranks and lower gearing than you used on an upright. Doing "leg presses" uphill will quickly tire out your muscles, and may lead to joint problems. -- Tºm Shermªn - 42.435731,-83.985007 I am a vehicular cyclist. |

Am sure I don't want to do "leg presses", as that sounds like a recipe for joint problems. I interpret "20° minimum knee bend when pedaling" to mean that my knee should never come within 20° of becoming straight, yes? Have been playing with the seat adjustment, and think I was at less than 20° yesterday, but more than that today. Thanks again, Kerry |

Heels flat on the pedals with your legs fully extended, or about a 20° minimum knee bend when pedaling. Make sure you are fully back in the seat when doing so. The fist bit of that is what I use as a rule of thumb, but note that rules of thumb are where to /start/, not where to finish. Fettle empirically fore and aft from that and test it to see it's right for you. I find on the 'bent I'm less sensitive to the exact distance than I am to saddle height on a wedgie. Others seem to find differently so you can't assume "set it /here/" advice will necessarily apply to you.

I find that I have huge knee problems when I can't get my leg almost straight when I pedal, but for many people having a few degrees of bend when the leg is extended more or less will not hurt. As always YMMV. Humans, deviating from the specification for 13 million years. |
