Hey I've got a used set of Echo 7075 CNC cranks and a Raceface bottom bracket but i only have one crank bolt. I was wondering if it was possible to use the trialtech isis bolts with this set up? http://tartybikes.co.uk/product.php?produc...;category_id=55 (these ones) Instead of getting the Echo ones which somebody advised me to get. http://tartybikes.co.uk/product.php?produc...;category_id=55 (these ones) Cheers, Matt
