Looking for spokes from a seller is at best way overpriced or just not possible. Online (ebay) there
are a wide variety of spokes to be found; there are even some who make up custom orders. When
you search, be as specific as possible to gauge & length. Measure twice, depending on your rims
length can vary even for the same size tire, so can price. I´m guessing the real issue is with the rear
wheel. Smart Samś are just too mushy for big riders. They are okay in front, but not on the motor
wheel. Leon, on their site, has admitted to the problem & ´sez´ they´re trying to fix it. In the meantime
I put on Schwalbe marathons, green guard, 70 PSI,( 29¨ x 2¨) with much tougher sidewalls, this after several
mtn, tires too soft to cut it, Marathon plus are too rigid at the tread & will distort sidewalls for a heavy rider.
Green guard are not really mtn tires, but just fine if your are not into shredding. The Moscow is a great uphill
bike, downhill,,,not so much.
