Coaster Brake Challenge #4

[CENTER][FONT=Franklin Gothic Medium]Rules for bikes:[/FONT][/CENTER]
[LEFT][FONT=Franklin Gothic Medium]Gearing: [/FONT]
[FONT=Franklin Gothic Medium]Single speed only. No internal geared hubs (sturmey-archer, bendix two speed kick backs etc.) no derailleur of any kind (A chain tensioner is fine but not recommended). No external gearing. No gears. No fixed gear. Each race will be different from the last and you may want a different gear ratio for each race and you can have any gear ratio you wish. We have found that 30-36 in the front and 18-22 in the back is the range best suited for this event, see what works best for you.[/FONT]
[FONT=Franklin Gothic Medium]Drive system:[/FONT]
[FONT=Franklin Gothic Medium]The rear hub must be a coaster brake. Single speed coaster brake only. No two-speed kick backs, etc (I know what they look like) Some coaster brakes are better than others, do your homework and get a good one. See below for more info. Cranks of any kind may be used as well as pedals. [/FONT]
[FONT=Franklin Gothic Medium]Braking system:[/FONT]
[FONT=Franklin Gothic Medium]Coaster brake only on the rear wheel only. No hand brakes of any kind. No secondary braking system of any kind. No drum brakes, no cables, rods, levers, etc of any kind. You pedal forward to go forward and back to stop. Nothing else. [/FONT]
[FONT=Franklin Gothic Medium]Frame:[/FONT]
[FONT=Franklin Gothic Medium]Preference for old double bar cruisers but there are no frame restrictions. We have found that cruiser frames and lower end frames with a horizontal dropouts work the best. Frames with a rigid dropout are difficult to get proper chain tension. We recommend the following types of bikes:[/FONT]
[FONT=Franklin Gothic Medium]Single speed mountain bikes[/FONT]
[FONT=Franklin Gothic Medium]Pros: take new bike goodies well[/FONT]
[FONT=Franklin Gothic Medium]Cons: Can be costly[/FONT]
[FONT=Franklin Gothic Medium]Cruisers [/FONT]
[FONT=Franklin Gothic Medium]Pros: Cheap and look cool too! Already have to correct spacing for a coaster brake.[/FONT]
[FONT=Franklin Gothic Medium]Cons: Don't take mountain bikes goodies like threadless forks etc. Most have 1 piece cranks. Heavy.[/FONT]
[FONT=Franklin Gothic Medium]Any 26" bike that has a horizontal drop out. [/FONT]
[FONT=Franklin Gothic Medium]Pros: Older Mountain bikes are cheap and plentiful and easily adapt to our purpose. [/FONT]
[FONT=Franklin Gothic Medium]Cons: None really, an ideal choice for this event. [/FONT]
[FONT=Franklin Gothic Medium]Forks:[/FONT]
[FONT=Franklin Gothic Medium]Any. [/FONT]
[FONT=Franklin Gothic Medium]Wheels/tires:[/FONT]
[FONT=Franklin Gothic Medium]You can have any kind of hoop/tire combo. I suggest a light wheelset that you've laced a coaster brake into. Something rugged is good, I've done each race with cheap alloy cruiser rims, they have held up fine thus far.[/FONT]
[FONT=Franklin Gothic Medium]Handlebars etc.[/FONT]
[FONT=Franklin Gothic Medium]Everything else is left up to the individual rider. [/FONT][/LEFT]

One week away!
