is the DVD player plugged in and is the disk inserted?
best ridind DVD ever, so so good. Me and Kyle L have started a porter fanclub. PM me if you want in!
A higher BB makes a bike more stable on the back wheel as you're further over the back, but less stable on 2 wheels 'cause there's a higher centre of gravity.
And lower BB vice versa. I'd say higher BB for comps 'cause you spend more time on the back wheel. Hence why most Koxx bikes are +55/60 bb.
