This Week's Failures
So, the plastic bike came with Ksyrium Elite wheels, and with maybe 150-175 miles, it's got a front wheel wobble -- something my conventional wire spoke front wheels never develop unless I smash them on a railroad track. It's a radially spoked wheel with conventional nipples, so it's easy enough to true -- just disappointing.
Meanwhile, with my son getting ready to go off to college on Tuesday, I was giving his 29er a once over. It's an Airborne Goblin -- great bike for the buck but spec'd with no-name wheels with super-duper sealed bearing hubs. When he first got the bike, shifting seemed good, but he went riding down the local elf trails and did something that put the chain over the big cog and in to the spokes. I extricated the chain, straightened the hanger and got the bike up and running, putting off replacing the damaged spokes until it was time to go off to college. So, yesterday I pulled the wheel to put in some spokes, and the right axle end falls off in my hand. The bike has less than 50 trail miles on it. I had an old beater Deore disk hub sitting around, so I rebuilt the wheel using that. The axle broke right at the margin of the bearing cartridge and looks like there was a fatigue fracture -- that sort of grey finish with a bright area of the final failure. It seems odd to me that wheels are now just something to hold up the bike on the showroom floor -- and its expected that you're going to go out and buy something that will last -- at least with the MTB. I think the Ksyriums are just not sturdy enough for a larger rider, at least at factory tension. -- Jay Beattie. |

I think the Ksyriums are just not sturdy enough for a larger rider, at least at factory tension. My rear Ksyrium died in the same way as a few others I've noted around here went. A crack through one of the spoke holes. Too much load on too few spokes. The front seems pretty good however. The only time mine has needed truing was when in a race, a fellow tried to ride between me and the inside of a corner in a crit. His foot went into the front wheel. It lifted the front wheel clear off the ground, and I guess we were lucky not to go down. Some of the paint from his shoe was on the affected spokes, and after a little tweak the wheel was true again. I confess though that since building a new front with a Mavic OP Ceramic and Miche hub with 32 radial spokes, I haven't used the Ksyrium. As the Miche hubs have a bigger and more wear resistant bearing too, I'll stick to my wheel until I destroy it some day. One thing's for sure, it won't be from wearing out the brake surface. That ceramic is the bees knees, the ducks guts, A1 to be sure. -- JS |

I know our roads suck but jeez. Not sure what's up with that. No flats since I got them last year and now 4 in 3 weeks. Same wheel. Rim tape looks ok. Haven't needed truing yet aside from a wobble in the rear caused by a fall. Meanwhile, with my son getting ready to go off to college on Tuesday, I was giving his 29er a once over.

Not sure about your wheels or weight but the Ardennes require a special wrap for riders over 190lbs. -- Jay Beattie. -- duane |
