The seals went, and the freewheel stopped working properly, although fortunately it didn't completely fail to engage. Result was new bearings and a new freewheel mechanism which with labour cost half the price of a new set of wheels!<br />My heavily used Swiss DT 1450s have behaved impecably through similar conditions.Unknownhttps://www.blogger.com/profile/12444704093143951785noreply@blogger.comtag:blogger.com,1999:blog-7865957007758842338.post-34620996806125414672009-09-17T18:12:16.697-07:002009-09-17T18:12:16.697-07:00The biggest reason I have been able to figure out ...The biggest reason I have been able to figure out for the G3 pattern, is spoke tension. I just had my Rolf Dolimites repaired and trued, and the mech kept stressing how much tension a paired spoke wheel needs. I believe I read on Campy's website that the adding the third spokes means much less tension. Now for a 140lb person, this may be a moot point, but for me at 6'2" and 225lbs (right about 100kg), this could mean a longer lasting wheel, more comfortable ride, and possibly less flex (?). I've had my Khamsin's for 2 years now, and have beat them hard on both my road bike and cyclocross/commuter bike. They are still true, and tough as nails, but a bit heavy on the road bike on the steep (but short) Maine hills.jazclrinthttps://www.blogger.com/profile/02114247072269959389noreply@blogger.comtag:blogger.com,1999:blog-7865957007758842338.post-32791373415702649462009-08-17T09:25:34.650-07:002009-08-17T09:25:34.650-07:00I would certainly agree using G3 on the front whee...I would certainly agree using G3 on the front wheel is bunk.<br /><br />On the rear wheel using twice as many spokes on the drive side makes spoke tension more uniform. The high dish on modern rear wheels translates to drive side tensions more than twice that of non-drive side. With equal number of spokes on both sides it is difficult to get the wheel tight enough so the non-drive side spokes will be tight enough not to back off.<br /><br />The old Roval wheels (not to be confused with the more recent wheels by Specialized also called Roval) used equal spoke spacing much like Fulcrum's offerings. It would be interesting to see an engineering analysis of using equally spaced spokes vs. grouping them together as Campagnolo does.Al Dentehttps://www.blogger.com/profile/12828407395018461322noreply@blogger.com
