I’d say go test ride a few other bikes, might help you decide what it is about the Heckler your not getting on with? I had a 2007 Heckler, loved it but never quite gelled with it, if you know what I mean. After trying a few other bikes I found it was the comparatively short front end. I now ride a Cannondale Prophet, same size as the Heckler, but the longer top tube means it feels quite different and this one is a keeper for a good while yet.
