I've been looking to put clip on aerobars on my bike and was looking at the oval concepts stem cap system.

luckily the bike came with an oval concepts stem when I bought it so naturally I decided oval concepts but I need some clarifications on all their options.

What do all these over/under, over/over, under/under terminologies mean? I assume it's the position of the aerobars and elbow pads with respect to the handlebars.

Then I see it comes in 26mm or 31mm, meaning that the stem cap is for 26 or 31mm handlebars?
I saw on slowtwitch that some people don't bother with the elbow pads, wouldn't that be a pain on the arms?

What are some experiences and setups that you've chosen with this system?

I had an over under system but sold the bike I was using the faceplate with. Hell, if you are interested in an over/under 26.0 faceplate and a set of armrests, give me a holler.

But to answer you questions:
1. yup face clamp size
2. I've ridden without pads and its okay for 10 minutes at a time, but I went with the armrests myself
3. I liked the system while I had it. It's fairly light, the armrests sit low, and it's fairly easy to install

thanks triguy, I think I finally get it. Did you like it over traditional style bars where it clamps directly to the handlebars? There's a bit of a price premium and was wondering if it's worth it.

Unfortunately I need a 31.8 faceplate
