I measured carefully this time, turns out my BB height is 10.7 inches, so now I have more room to work with.
The frame can take about 26x1.75 as the max size for tires. 2.0 if I am careful and the frame and wheel are true and centered.
Currently running 26x1.25.
If I switch to 24x2.0 my bottom bracket height will drop .25 inches.
If I switch to 24x1.75 my bottom bracket height will drop .5 inches.
Current bottom bracket height is 10.7 inches. I prefer a lower BB height since I use my bike to commute in stop and go traffic.
What are people's thoughts about this?
