Increasing OLD comes up fairly often with your customers, does it?

Like I said, if you don't often find yourself on the small cogs, I really can't see the big deal of giving yourself 3mm of leeway to make a stronger wheel. As far as the chain's concerned, the cogs are only there to the extent you use them.

Also, it's the fact that you're intermittently SHOUTING that's (kinda) random, and as I said, distracting.
