what coatesy said, you need the new hope 12mm axle and end caps. Due to bearing size the axle is a bit thin, and when used with a maxle lite tends to snap (been a few threads on here and loads on the wider tinterweb) for the reason coatesy explained. A lot of people replace the maxle lite with a BETD axle which costs an eye watering 45 quid for what is essentially a 6 inch long 12mm diameter bolt. CRC do something similar for a more reasonable 25 quid

and I nearly bought a land rover cylinder head bolt new off ebay for about £6 to do the same job (appeared to be right dimensions and made of stiff, tough but heavy steel). I should probably buy a load, re-package them as a DH upgrade and sell em at 20 quid a pop…
I suspect the Pro 2 Evo was Hope’s admission that the Pro2 couldnt really cope with 12mm axles, Hope advised me against using Pro2 with a maxle lite when I enquired on how to convert mine (having bought a frame with one), which is a bit cheeky when Orange supply bikes built with 12mm Maxle Lite and Pro 2s…
