    [SIZE="4"]Inside The Pros’ Bikes
    Duncan Riffle’s Chumba F5
    [/SIZE]

    Weight: 38.5 pounds Estimated cost: $6000

    With two national downhill titles to his name, Santa Barbara, California’s, Duncan Riffle would seem to have no problem finding sponsors. However, with the economy slipping sharply over the last year, Duncan, 22, found that sponsorship money was drying up faster than a water bottle on a hot, summer ride.

    Rather than quit racing and go back to working for his dad’s construction company, Duncan came up with another solution. He created his own team, Team Duncan Riffle Racing/Giantnerd. Duncan became the team owner and captain, and added pro Brad Benedict and junior expert Andy Becker to the roster. Duncan lined up a group of sponsors to fund the team, and set off to race the World Cup downhill circuit. Here is the bike he is racing.

    1. Chumba F5 aluminum frame, size large, 8.5 inches of travel.
    We are using custom links that lower our bottom-bracket height and slacken the head angle. Chumba is making this upgrade available to all Chumba riders. This frame is light, responsive and very strong, with a proven suspension design.

    2. 2010 RockShox Boxxer World Cup fork. 7.9 inches of travel.
    RockShox’s 2010 model Boxxer is by far one of the best forks I have ever ridden: extremely stiff, yet responsive, with far more adjustability, internally and externally. It’s very light and strong.

    3. Maxxis Minion DHF 2.5 3C tires.
    By far my favorite tire of all time— great reliability and durability. Ultra-grippy rubber allows for amazing traction in any conditions; flat-resistant sidewalls allow for lower pressures and a great feel.

    4. Maxxis Welter Weight inner tubes, with presta valves.
    Thanks to Maxxis DH sidewalls, we are able to run these medium-weight tubes to keep our bikes light and the rolling-wheel mass down without pinch-flatting.

    5. Mavic Deemax wheels (hubs, spokes, rims).
    A great balance between durability, reliability, strength and flexibility. The rims are strong, yet supple, to allow for a smooth ride that you can trust at speed and on rough terrain. The new Deemax hub allows for immediate engagement when pedaling out of corners and tight sections.

    6. Avid Elixir CR brakes.
    This is Avid’s all-new brake, which is one of the best-feeling brakes I have ever ridden. Pad contact and lever reach are adjustable on the fly with no tools whatsoever. It has loads of power and is super lightweight.

    7. Sunline V-One, 32-millimeter rise handlebars.
    Strong and comfortable with a great bend and rise.

    8. Truvativ Team Double Clamp seatpost.

    9. SunLine Big-S lock-on grips, black.
    Great mid-size grip, comfortable and lightweight.

    10. Truvativ OCT cranks, 170-millimeter length.
    These cranks are strong, lightweight, extremely durable, and very stiff, so that your power is put down and not flexed into the crank arms.

    11. Gamut 34T chainring.

    12. Gamut P40 chainguide, with custom yellow bashguard.

    13. Crankbrothers Mallet M pedals.
    These pedals have side-to-side float, allowing for better balance and control on the bike.

    14. SRAM hollow-pin chain.
    Strong and lightweight; it’s the only chain I trust.

    15. SRAM X.0 Shortcage rear derailleur.
    It is a quick-and-crisp-shifting derailleur. Light and stiff spring tension keep chain slap at bay, no matter how rough the conditions.

    16. SRAM X.0 rear nine-speed shifters.
    Carbon and Ti hardware make for a beautiful look and offer quick, sharp and responsive shifting.

    17. Avid eight-inch-brake rotors, front and rear.
    Avid’s new rotors are designed to dissipate heat and increase stopping power better than in the past. They are strong and reliable, with incredible stopping power.

    18. SRAM 11-21 rear cassette.
    We keep them small and strong, so we go with SRAM. With downhill there is not much need for the easier gears, so we keep the range tighter for more precise, quick shifting.

    19. Fizik Tundra seat.
    Custom Team DRR/Giantnerd colors with white leather sides and a yellow strip center. This seat is extremely comfortable and strong, capable of handling a few set-downs and impacts. The small profile keeps it out of the way and right where you need it.

    20. SRAM cable. Custom yellow housing.

    21. Crankbrothers Cobalt SL headset.

    22. RockShox Vivid shock.
    Custom A-Tuned shock with a light top end and extra stiff bottom end. This shock is extremely tunable, with beginning and ending stroke rebound as well as external compression adjustment.

    23. Titanium hardware.
    Most of the hardware on the bike is titanium: rotor bolts, brake-mounting hardware and brake assembly hardware bolts come with Ti direct from Avid and SRAM.

    24. Bar extension plugs by Andy Webber.
    The great thing about these is they are removable, so you can go from bar to bar with no worries at all. You can add a little extra width to any bar with these lightweight, strong bar-extension plugs.
