Often I want to know the front center of an existing bike frame, but very few geometry charts list this value. However, geometry charts almost always list the wheelbase, bottom bracket drop, and chainstay length, and the front center can be calculated from these values. Here is the relationship: $latex FC=\left(\left(WB-(RC^2-BBD^2)^{1/2}\right)^2+BBD^2\right)^{1/2}$

Having grown up in a place where the weather … Continue reading SaltAir

This disappointing combination makes for a particularly loud and unenjoyable experience during the 12-hour, 750-mile … Continue reading Speaker Bracket
