I'm debating running a regular gear ratio with tiny chainring/cog. I've got a 36t ring and 14t cog sitting around and I'm curious if anyone has run something like this for any length of time? Its 69 inches so it will work great around here as far as the actual ratio is concerned.

Any issues with excessive wear? I've been getting 1200-1500 miles out of my chains and 7000-8000 miles out of my cogs, this is with pretty normal 46 chainring and 17/18 cogs.

I ask because even when the ratios are essentially the same the ride feels a lot different. I spent about a year on 46/18 and loved it, often going to 46/17 for flatter rides. Gearing felt good, easy to spin, nice power on the hills and really matched my riding style. When I switched to 52/20 which is about the same ratio (70 inches) I hated it. The ride felt sluggish and I never felt like I had a good spin, maybe due to the added mass in the extra chain links and larger ring/cog? I'm not sure, anyway if you have input that would be great.

Thanks
