Cialis Levitra Sales Viagra

Cialis levitra sales viagra Some commuters are unstoppable, cialis levitra sales viagra and our friend Matt was going through two chains a year commuting in snowy, cialis levitra sales viagra slushy, cialis levitra sales viagra salty and gross western Connecticut winters. Cialis levitra sales viagra He had the weather-proof solution: an 11 speed Alfine internally geared, cialis levitra sales viagra belt driven, cialis levitra sales viagra disc-braked super commuter, cialis levitra sales viagra and I’m psyched he asked us to build it for him.

Cialis levitra sales viagra I’d done one belt drive before, cialis levitra sales viagra a single speed, cialis levitra sales viagra but the Alfine hub, cialis levitra sales viagra coupled with the desire for fat tires, cialis levitra sales viagra creates some new technical challenges. Cialis levitra sales viagra Belts are wider than chains, cialis levitra sales viagra but more importantly they need to run perfectly straight – if not the belt will literally walk off the cog or sprocket. Cialis levitra sales viagra [This is one reason for the new Center Track system, cialis levitra sales viagra which allows for more flexibility]

Cialis levitra sales viagra Even with chain drive, cialis levitra sales viagra providing clearance for chainrings and wide chainstays can be a problem. Cialis levitra sales viagra Here, cialis levitra sales viagra it’s worse – the belt is wider, cialis levitra sales viagra the “belt line” has to be perfect, cialis levitra sales viagra and to top it all off, cialis levitra sales viagra the rear cog on an Alfine hub is set in away from the dropout, cialis levitra sales viagra to accommodate the shifting cable. Cialis levitra sales viagra I did some fancy crimping of the chainstay, cialis levitra sales viagra so here it is, cialis levitra sales viagra built up with 26×2.3 tires, cialis levitra sales viagra ready for action:

Cialis levitra sales viagra Here are some shots of the build in process:

Cialis levitra sales viagra When Matt and I began discussing this bike last year, cialis levitra sales viagra we weren’t sure how best to break the frame (the belt doesn’t come apart, cialis levitra sales viagra unlike a chain, cialis levitra sales viagra so you have to be able to get it inside the rear triangle). Cialis levitra sales viagra Fortunately, cialis levitra sales viagra Paragon came out with a belt option for their sliding dropouts. Cialis levitra sales viagra These are great for disc brakes, cialis levitra sales viagra because the caliper stays aligned to the dropout, cialis levitra sales viagra and for belt drive systems, cialis levitra sales viagra as they have integrated tensioners. Cialis levitra sales viagra Belt tension is super important for proper performance. Cialis levitra sales viagra Here are some shots of the dropouts during construction, cialis levitra sales viagra and of the frame before components. Cialis levitra sales viagra You can see how I weld on a section of tube, cialis levitra sales viagra similar to how we do capped stays:

Cialis levitra sales viagra And here are some shots of me mocking everything up before the wheels were built:

Cialis levitra sales viagra And some of the completed frame. Cialis levitra sales viagra The Paragon dropouts are stainless, cialis levitra sales viagra so I was able to polish the interface where the frame breaks:

Cialis levitra sales viagra And some more shots before components. Cialis levitra sales viagra Note, cialis levitra sales viagra the bottom bracket below is just one I had lying around that I used to determine the alignment; in the complete bike pictured above, cialis levitra sales viagra it’s a narrower Phil that fits properly.

Cialis levitra sales viagra Next up: Belt drive again, cialis levitra sales viagra this time a single speed! And super-lightweight S3 tubing fever! Weld-o-Rama 2011 continues!
