We recently purchased a 2012 Cannondale Road Tandem 2 and have loved the few rides we've taken with it so far, but 2 rear spokes have recently become really loose. When we first purchased the bike, I had my mechanic go over the wheels to assure that spoke tension was correct. He made some minor corrections but overall said that everything looked good. Last night I noticed that the 2 spokes on the rear non-drive side on either side of the valve are dramatically loose.
- HUB: White Industries Mi6 Disc
- RIM: Sun ME14A w/eyelets, 40 hole
- SPOKES: DT Swiss Champion, 14g
- TIRES: Continental Ultra GatorSkin, 700x28c
- NIPPLES: Standard Brass
- Triple cross on both drive side and non-drive side.
- TEAM WEIGHT: 420lbs (I'm 6'4" and she's 6')
- WHEEL MILEAGE: Only about 45 miles
- The rear wheel is still almost perfectly round and true.
- No major bumps, drops, or other noticable hits to the wheel.
I'm an avid cyclist and have been for years, but I've never been a wheel builder. Any thoughts on what might be causing this? Lack of loctite on the spokes? Spoke count too low? Cheap spokes? Some sort of random planetary alignment?
Thanks for your thoughts.
