2 and 2.5 mm Allen Keys...What for?

I recently bought a mini-tool at my LBS. I didn't really need it, but it was on clearance. The price was too good to pass up. It includes 2mm and 2.5 mm allen wrenches. Now I have those wrenches in my home tool kit. They see only rare use. I can't quite fathom out why I would need them on a take-along mini-tool. What would I use them for at the side of the road or the trail?

They are sometimes used on road bikes.

I need a 2 mm wrench for the XT V-Brake adjustment. Unfortunately there is not such piece included in my multy-tool...

Perhaps you miss my point. I realize that tiny Allen keys are sometimes needed when the bike is on the stand. I'm asking what use I would have for them when broken down by the side of the road or trail. I really don't expect to adjust my brakes, road or mountain, while out on a ride.

If they are causing you soooo much greef! Clamp the offending allen key in a vise and strike smartly with a hammer! Make sure to wear protective eye wear also! You should not be bothered by them any more!

Perhaps this tool is the Swiss Army verson, designed by the Boy Scouts (be prepared).

Go ride your bike.

Well, if you happen to have one of U.S.E.'s new Alien seat posts and somehow knocked your seat out of alignment (nose up/down - seat fwd/back) you'd need the 2.5mm to loosen the two clamp bolts. Worst clamp design I've seen yet but, hey, it's light.

Say you damage a cleat and need to make a pedal adjustment... I think 2.5mm is used for that.
