Not sure if this exists anywhere but I'm looking for a quick change ratchet allen key set? I know park tool have recently released the QTH-1 and I am looking for something similar but with a ratchet and maybe a slightly longer handle to save my wrists. Any suggestions would be great as I have searched everywhere and not really found much out there.

Metric allen key socket sets should be readily available from a hardware store or e.g. Harbor Freight:

If you don't want to carry around allot of large tools then the screwdriver type bit ratchet sets made by Topeak, Silca and others are a good type of tool.

As John posted I use 1/4" drive up to 6mm and 1/2" drive above on my stand, a buddy has a Snap On 1/4" drive I want with an articulated handle to fit tight spots. That Park Tools looks pretty nice.

I do have one of these sets already but I'm looking for a quick change option (single hand operation and not fiddling around taking bits off and on) .
I think maybe I will have to make some kind of bit holder with the hex shapes cut out. Possibly with a magnet on the back to keep the bits in place.

Something like this, maybe? This is a representative sample only, not a specific recommendation. Many others seem available.

This example doesn't specify the hex driver size used. Seems to be made to fit screwdrivers using interchangeable bits, so I'd guess maybe 1/4" - but I don't really know..

With the appropriate size socket, you could just change the bit vice having to change the socket. At least some sets I've seen are specified as being magnetic.

Here are some options mini ratchet wrench set - Bing You'll have to narrow the choices down to wrenches that have metric hex bits and not T-Handles like OP mentioned from Park Tool but these will give you more leverage and would be less bulky to carry in a seatpack if you wanted to and less $$$. Check reviews on any of these as quality can be questionable on some of them. The Park tool really does look like a nice, quality tool though but not cheap.

I may have found a solution to my problems. Using an old dewalt bit set holder I can fit a 6mm,5mm, 4mm hex and the release button on the ratchet that I have works really well for single hand operation. I have just ordered a rectangular magnet so I can attach the holder and the bits to my work stand. I will post photos of the finished project if all goes well. And thanks for all of the suggestions so far.

Another approach might be to get some additional 1/4" ratchets, so that you can leave a few very-frequently-used bits more or less permanently installed on their own ratchets.

If you ride in wet conditions, you might consider slathering the rust prone tools in a rust inhibiting lubricant stored in a drip-free parcel.
