All I've been able to find is 1" as well but I previously asked about this and some people find it may be dangerous. The cable operation is not as smooth, and could bind. If the spring ever breaks, and cable binds, you may find yourself going full throttle through a red light
so I would go with the push pull if they exist as an extra precaution. On another note, seaweb, I remember you saying your frame was bent. Is everything all good now? How's the weather on the west coast? I just moved back to s*itty Ontario and miss the ocean, mountains etc.
