I currently use Avid AP3 levers with my Ergon GP5s. The Avids are 'shorties' and seem to work very well using two fingers. There is limited space available for hand movement owing to the GP5's grip shape, my hands and the position of the 'horns' Bearing that in mind: I was wondering if using a 'standard' brake lever such as a Shimano LX Deore was possible or desirable. If you are using GP5's which levers are you using? I think Bikerta has GP5s?
