Bike noise, creak, click, creaks, clicks, clicking, pinging sound - help

the Athena crankset and BB has got me scratching my head: external BB cups and 2 piece crank, but I can't work out how to remove the cranks.

<2011 UltraTorque or 2012 PowerTorque? UT cranks are removed with an 8mm Allen Key* plus a small screw driver to get the circlip off the drive side cup, PT needs a bearing puller and, apparently, a suitably shaped piece of official Campagnolo cardboard.

• Kidding; unless you have extraordinarily long Allen keys, you need the UT-BB110 tool
