What is the cable routing like on the Smoothie HP

The Smoothie HP runs shifter cables and the rear brake externally along the downtube. We believe that bicycles with with internally routed create maintenance headaches that outweigh their benefits for this type of bike. The frame is compatible with old school downtube friction shifters. A nylon plastic cable guide is screwed into the bottom bracket shell. The matching carbon fork has internal routing. Cable guide braze-ons need C-clips(included) or zip-ties to hold the cable housing to the frame.

1) If you are not using downtube friction shifters, you need to purchase downtube cable stops to cover the bosses and to create an guide point for running cables.

2) We recommend sheathing exposed shifter cables on the downtube and bottom bracket with Teflon cable liner. These are inexpensive and helps keep the cables from a build up of dirt and grease on the plastic cable guide. Also reduces corrosion if you are not using stainless steel cables.

3) It is common on bikes that cable housing can rub on the paint of the bikes when you turn the bars. We recommend getting stickers (cable dots, frame protection tape) applied in areas you see rub.

Do you have build recommendations for this frame?

For most of our frames we usually don’t recommend much beyond stay practical and reliable. For the Smoothie HP– since it is a little more purpose-built for a certain type of performance– we would recommend faster, lighter wheels and tires with fast rolling casings. They will help you spin up to speed faster and the frame will help you maintain momentum. Not wiggly light wheels; you do want some stiffness for cornering. We think this is more important than deep aero wheels, but build it however you want.
