Before I start I should say I'm a cup and cone man, but I have these Aksiums.
The wheel seems very flexible. If I grip the wheel and chainstay with one hand I can make the wheel touch the stay just by squeezing.
And if I 'wobble' it by the brake it clearly moves from side to side.
Now with C&C play is easily identified by knocking at the hub. Do sealed bearing wheels feel the same? because these don'r seem to knock or grate.
The spokes are set far softer than all my normal road wheels.
Any ideas.
My bearings are rock solid and my spokes about as high tension as I dare take them but grabbing the rim and squeezing it over makes mine hit the sides too. Wheels have some flex
You've got some spokes missing.
Someone forgot to tension the spokes.
You're superhuman strong.
Sealed bearings knock when they're goosed, just like loose cup and cone.
The brake is released I take it? Sometimes the feeling of the blocks touching each side of the rim while checking for hub play can feel a bit like hub play. Had a customer not so long ago that turned up worried about this and I quick released his brake to 'tighten his hub' ;O)
lightweight wheels are very flexible. get stiffer rims, increase spoke count or do both.
bladed and super thin butted spokes cause more flex too
My Focus Cayo came with Aksiums as standard and I noticed a massive improvement in stiffness when upgrading them to Ksyriums e.g. I stopped getting break rub on steep climbs when I was honking it.
I've got five other wheel sets, four 'normal' sets and a lightweight 1300g set and none of those flex.
When I'm moving the wheel, it's only between the thumb and fore fingers.
So I might try nipping them up. Last year the front wheel did an odd thing. The wheel stayed perfectly true but moved to one side which made it look like you where 'crabbing' along?
Double post, sorry.
Not sure about Askiums but my Roval's have sealed bearings but still allow for pre-load tension on the axles. Sounds like you have a combination of cheap flexy wheels and not enough pre-load.
I had some aksiums and they were just a bit flexy. I could easily get them to touch the brake blocks when climbing.
Same setup as druidh (Focus Cayo). Problem stopped with my RS80 replacements.
Feels like I'm about to roll a tyre when I'm pushing along.
Sorry,I misread the prob and replied first time around. Can't add anything helpful. I do remember trying out a pair of dura ace wheels years ago and the first thing I found (riding up Blackfold near Inverness,if anyone knows the climb) was that I had to q/r the brakes as the flex was doing my head in. Luckily never bought them and went back to the dura ace hubs/open pro's I built in the first place.
I had play in my rear aksium, and discovered the plastic preload caps which it never occurred to me would be fitted to hubs with cartridge bearings. Slight tightening sorted the play, had no adverse affect on smoothness of bearing and wheel rotation.
I ride Mavic Aksiums but I've never considered the need to do this before.
But having read this post I just tried it. There is flex but I really, really have to pull/squeeze hard to get the wheel anywhere even near the chainstay.
I ride these loads and have never felt the flex when riding.
