2014 Fuji Single Speed/Fixed Gear

2014 Fuji bikes are beginning to be stocked by dealers in many places. I'm looking for a steel (non-hi-ten) single speed bike. Fuji has three models of single speed bikes: Feather (MSRP: $554), Declaration (MSRP: $489), and Track Classic (MSRP: $489). Please do not assume Feather is the best just because its MSRP is the highest.

So what's the benefits of each model? The Feather and Track Classic are made of 4130 cromoly steel making them lighter than the Declaration's frame which uses high tensil (hi-ten) steel good enough for kid bikes. Almost bomb proof if I'm not mistaken. Feather being expensive has the best looking pedals by far (alloy instead of plastic). The Feather and Declaration both come with flip flop hubs for versatility if you're into flipping wheels. Track Classic comes only with a fixed cog but I'm a full time fixed rider and the lack of free wheel and cog makes it lighter for me. Maybe the objective of Declaration is fixed gear free style (FGFS) because it comes with thicker tires (28mm) and made of the very strong hi-ten steel. Feather is by far the classiest in terms of stems. It comes with a quill stem instead of the more common stem + steerer.

First thing to note is the frame material, i.e. Elios 1 and Elios 2. These are two types of custom steel. Elios 1 is a "straight-gauge steel tubing, made with high-grade, high-tensile steel. This frame material offers a superior strength-to-weight ratio for bikes that are built to last." Elios 2 is a "certified CrMo (chromium molybdenum) blend that is cold-drawn and custom-butted. Two wall thicknesses provide strength in high-stress areas and allow for decreased weight in other parts of the frame."

A customer at the bike shop I work at brought in his Fuji Track Classic. The red decal on the top tube is really noticeable. The bottom tube actually comes with eyelets for a water bottle cage. Although the rear hub comes with a single cog, the other side of the hub is threaded. This implies one can attach a free wheel and Fuji just didn't bother with "flip-flop" hub to keep the cost down.

Thoughts on deep dish rims and durability: Jaime shared some ideas with me about durability of deep dish rims after I went on about trade offs between aerodynamics vs durability vs weight concerning wheels. He confirmed that I am correct when I say deep dish rims + high flange hubs are more durable by shortening the spokes. The side effect of using the combination is the spokes have less play and therefore stresses the rims more, decreasing durability of the rim itself.

In track racing the priority of the three issues described above would be prioritized as: aerodynamics > weight > durability. Deep dish rims weren't designed for the purpose of durability but for the advantage of aerodynamics. Then what's important for the poor street riders, whom includes me, where hills are involved? I would order them like so: durability > weight > aerodynamics. This prioritizing can be further complicated by adding aesthetics and cost.

Premium Rush Bicycle

Recently, I rewatched Premium Rush and became curious about the bike Wilee (Joseph Gordon-Levitt) rode in the movie. I stumbled upon a blog entry at FixieFamous.com regarding the components used on the bike. They broke it down, but I decided to expand on it by adding links to the manufacturers of the components.
