I've really been enjoying the Motobecane Fantom Cross Uno singlespeed cyclocross bike, but was not happy with the bottle cage placement. I have a Backcountry Research Mutherload strap to hold a tube, mini tool, and patch kit, but had to mount it under the down tube near the bottom bracket. Sure, I could have put it higher on the seat tube, but I was going for a lower center of gravity. After scouring the interwebs, I came upon Mount Skidmore in Australia and their bottle cage adapter.
The adapter came in a nice little bag that can probably be used as a dry bag for an iPhone. I have a Samsung Android phone that's just a little too big for this bag. I did however find it useful to hold replacement parts for my gardening shears. Perfect.
As you can see in the above photos, the adapter allowed me to push the cage up to give enough room to place the Mutherload on the seat tube at the bottom bracket shell. Other benefits are that the bottle is now a little easier to grab and I have the option of mounting a second bottle in a reasonable location. Well, there aren't bottle cage bosses on the seat tube, so I have that little issue to deal with.
This is a really well made handy product that is well worth the price. Also, shipping to California from Australia was pretty speedy. I hope they come up with other nifty products.
