Calculate effect of lighter wheels?

**[email protected]** · #1 January 19th 13, 03:48 PM posted to rec.bicycles.tech

Hi All!

I've scrounged up a new wheelset for my track bike.

I wonder if anyone can help me calculate my theoretical time savings for a standing start 250m?

Assuming the moment of inertia is the same, it's just the mass.

All-up weight 105kg, 250m time of 20.0 sec.

Old wheels: Front 1350, rear 1700g. New wheels: F 850g, R 1250g

So all-up 104kg with all that taken from the wheels = how-quick 250m?
