Number of Cables - the number of cables the guide is designed to accept.

Guide Type - some setups require specific guides for the derailleurs to operate correctly. Tunnels simply act as a channel to guide the cable whereas stops create an end point for the cable housing, giving the cable the leverage it needs. Bar control stops are required when using handlebar shifters if your frame doesn't have any guides or braze-ons.

Tube Diameter - most steel (and early lugged aluminium) frames will have a down tube of 28.0 mm - 28.6 mm, this was standard for a long time but there are 'oversized' steel and aluminium tubes that have a diameter of 31.8, 34.9 and even 38.1 mm.
