I have a pair of 181mm CQP (Cook Quality Products) Cranks. Silver arms with black spider. Fitting is standard 5 arm 110mm/74mm BCD chain rings with square taper fitting. The crank arms were CNC'd from billet
They are similar to Cook Bros cranks (as there was I understand some connection between the 2 companys).
Whilst I will post to Peru the cost might be quite expensive as I will not ship these with insurance unless you are prepared to take the risk.
Drop me a PM if interested and I'll get some pics off to you but could I have an e-mail address for this.
