B33 Crank balance factor

[Nicky Burgess]

Hi,

I am currently rebuilding my B33 and I am struggling to find any information on what balance factor I should be using for the crank. Does anyone what they were set to from the factory ?

Or as I plan on using the bike a lot on the road does anyone know what would be a good balance factor for this type of riding ?

Thanks,

I think it's around 55%.
