Truvativ Rouleur BB/Crank installation question

Does anyone know if it is necessary to install the clear plastic shell
assembly that connects between the two bottom bracket cups? The manual
shows it being installed, but when I do it rubs against the screw used
to hold the bottom bracket guide to the bottom of the frame. I'm just
wondering if it serves any purpose.

Thanks,

KJ

The BB will work without the plastic sleeve, but it serves a useful
purpose: it helps seal the bearings. I'd want the sleeve installed if
it were my bike.

I'd consider shortening the screw used to hold the bottom bracket cable
guide to the bottom of the frame, or just install a washer (or presta
valve nut) under the head to keep the end out of the way so you can
install the bottom bracket sleeve.

Thanks. I'll get a shorter screw. And thanks for answering my question.
Unbelievably, SRAM/Truvativ does not have one e-mail or customer
service number on their whole site!

Put a wee washer onto the screw that holds the BB guide in the shell.
KEEP the plastic sleeve.
