The Cache bottle holder has the side entrance (to adapt to all frame sizes) and is combined with a tipper for use with the left or right hand or for mounting on the saddle tube (where it is necessary to reverse the entrance). For mounting on the oblique tube the design has been optimized for the recessed section on the Spark but it will work with all the bikes. One aspect we have paid particular attention to is the retention of the bottle and our engineers have conducted extensive tests to ensure that the bottle remains on the bike for when you need it.
