Per Request..2 bottle Adapter now avaiable
This is a robust seat post mounted water bottle cage/bike kit capable mount (Minus the bounce you get from some of the seat mounted designs). In it's basic concept this is a mount that attaches to your seat post (check models, will do requests for special sizes or hole patterns) You can easily add 1 water bottle, 2 co2 catridges, inflator head (microflate works great), and a tube possibly 2 with tire levers. And clears weird seats like the ISM's with leaps and bounds. Another cool thing about this design is that it's not printer intensive, short print took 4 hours on my Fusion 400 at 4500 mm/min 1.75mm abs at 0.25mm layer height, solid.
For Felt DA1 model it mounts to the DI2 pattern on rear of seat post
27.2 & 31.8 it snaps on I recommend zip ties and a wrap of electrical tape under neath for grip.
Water bottle mounts are setup for M5 screws and nuts
The hotshot mount is for mounting the cygolite hotshot under it again M5 screws
For C02 and microflate head I recommend tapping hole out but screwing the cylinders can work, same for the post run a die over it will give clean threads
Tubes should Velcro nicely under the bracket. i like to put my tire levers in the middle of the tube seem to stay nicely. See Pics Usually use 2 straps.
As every bike is different let me know if you need a mod. you'd be surprised by how many others might be able to use it.
Tap And Dies
As I stated above if you intend to use the CO2 holders running a tap and die over then helps a ton. 3/8-24 threads
