Hypothetical frame and wheel weight question
Take your tyre off your front wheel, hold the bike in the air, spin the wheel fast, turn the bars about. Repeat with the tyre back on.
thanks, i have not considered the impact of angular momentum. would that have a big impact in how the bike handles then?
What I am really after is where it would be best to cut weight off my bike. If I replace my frame with something thats 1kg lighter vs replace wheels with wheels that are 1kg lighter – which would be the best option for single track?

Keep going until you have a negative weight in the wheels
thanks mike, do you mean that lighter wheels are always better than the same weight saved on a frame for example?
i thought so too, at first. but i am interested in the steering response. take fo example a car – at high speeds on a curvy country road you do not want super light steering right? its better for the steering to be a bit ‘heavy’. some cars like BMW’s? servotronic I think would actually make the steering less sensitive at higher speeds.Posted 4 years ago
Something I wonder about quite often lately.
Say we have two bikes, A and B, on flowing single trail going slightly downhill, but not much.
These bikes only have frames/forks and wheels nothing else.
Bike A: Frame weight 1kg, wheels weight 9kg (total 10kg bike weight)
Bike B: Frame weight 9kg, wheels weight 1kg (total 10kg bike weight)
How would the ride characteristics differ going around bends and corners? Which one would be best for say going around a long smooth bend at say 30km/r?

Why not take into consideration the pressure and volume of the tyres? If Air weighs about 1.15g per litre at sea level with an atmospheric pressure of 14.7 PSI the rotational weight on your bike will increase with higher pressures/larger volumes.
In all seriousness to the OP’s question i have no idea. Im guessing the lighter wheels will feel more agile on a twisty trail but in a straight line they will probably feel the same.Posted 4 years ago
