gear ratio

anybody got any idea on gear ratio 27t brushed stock with 78 spur thanx:bored:

29T pinion should give around 6.5 (78/29 x 2.43 if I remember correctly and you have any XXX bar the BK2 which has a different 'box) which should be OK with a 27T. I admit I've even run 23 or 24 /78 with a 10 single so you're not going to be over geared!
