Great site. A quick one:
The Bighit 2003 came out standard with a 24″ rear wheel. I’ve changed the seatstay to accommodate a 26″ wheel and I use the most progressive (bottom) hole on the frame and position A on the shock link. How will this affect the headtube angle? I do a lot of DH and some “downhill” freeriding if I can call it that. I know with the 24″ rear wheel the slackest angle is 66.3 degrees, but I’m concerned it has negatively impacted that angle. I have a 2004 Boxxer Team up front – 7″, and a Fox Vanilla RC at the back.
I raced that bike for a couple seasons. Loved it. I’m sure it’ll be even better with a full sized wheel.
I think that change will steepen your head angle by about 1.2 degrees, theoretically to about 67.5 degrees. These days that would be considered a good “freeride” head angle.
Real quick, here’s how I attacked that question:
