The guides are still on there, the screws were about 3 mm longer than the stock ones to compensate for the raised height due to the thickness of the cage. Hope this helps and the cage works a treat with a 620ml bottle, never lost one yet and it is easy to get to when on the bike.
@LUCKYMULLEN: That helps a lot! I really wanted to run my 600ml bottle that I normally run on my nomad. I just happen to have longer screws that i have from a frame pump too. The roll cage is on it's way as well. Thank you!
