flubbed the sizing. Only solution according to Evotion is to buy a new one.
Measuring yourself can be hard, but if I remember correctly you weren't off by very much. With the Cage 7 and Cage 8 we can't change the shaft diameter without changing the straps (that's just the way the design is). Bijou and Orion are easier to make adjustments on. We offer discounts on redos, get in touch again to discuss your options (we have lots of options!) ;-)
The quality was excellent but I threw it out. a cage without a base ring doesn't work for me
