Max Load of a bike

[PennyFarthing]

When the manufacturer states Max Load - is that strict (ie you can be no heavier) but also I presume you include anything else you carry on that bike - or is there room for 'more'.

Yours, not a lightweight (well not in the Pub anyway)

i think if we was to all stick to the recommended stock load weight i don't think any of us would riding. Well maybe the fly weight cyclists.

A bike has to put up with alot more than say 85 kilo's for example. There would be alot more stress and load points when hitting a bump than a max load point. I'd imagine my bike with me, bike and luggage exceeds the 100kilo mark.

I wonder about the value of maximum load figures, since I've known of many broken frames that have been used well within their recommendation. We've seen a few of them in this forum and it's a phenomenon that has become far more common in this era of alloy frames.

well alloy tends to crack where as steel will bend to a certain degree.

I'd hope cracked frames are due to manufacturing faults or the wrong tempers.

Indeed, and it's why alloy framed bikes are generally less comfortable than steel framed ones.

From my early Tech . days in the 50`s , I recall that the shock load design criteria was twice the normal load !
