Any remedies? It seems the twist comes from the lower half-tubes. I have the stock fender brace all tight and assembly is good.
WTF can I do to button these up tighter?
EBR twisting...
Re: EBR twisting...
maybe make a more stout brace?
Re: EBR twisting...
That is what I am thinking...It only twists .5" side to side when I apply pressure to the wheel, but sometimes I ride and it is not centered.
It is REALLY annoying. :/
Re: EBR twisting...
sounds like a bent axle to me.
Re: EBR twisting...
I don't think so...I can see the lower half's moving--brace isn't solid?
Re: EBR twisting...
beef up.
Re: EBR twisting...
That looks like it would act like a big spring.
Re: EBR twisting...
Which way is it moving?
Left to right or front to back or twisting?
You can try using thicker washers on the axle and shortening up the spacers and use slightly larger washers on the inside of the front wheel mount. It will help to spread out the tourque and stiffen up the legs alittle.
Re: EBR twisting...
Looks a lot more rigid than the tubular braces... I like it!
Re: EBR twisting...
tubes are way more rigid than a mild steel bar!
Re: EBR twisting...
Since we are talking twist and if his bar is steel vs. a shitty alluminum tube, with the width and thickness of his brace I bet it's way more resistant to a twist than a tube... If the resistance was applied from side to side, it would be a different story.
Re: EBR twisting...
Twist is side to side...I might try to shim the axle with washers and put a lil force outward. The tube brace I have isn't really moving.
Re: EBR twisting...
So...I tried loosening everything and then re-tightening it all--still flexes side to side. Im not sure there is a cure for this other than bracing the lower halves at the top of the tube below the boot to 'square' it.
I'm pretty stumped.
Re: EBR twisting...
I had a similar issue with my moby.
The front end would always stay too far too the right and never seem to stay straight.
It ended up being a bent axle - it doesnt take much of a bend to make it feel all shitty.
It is an easy thing to take for granted and only takes a minute to check.
Re: EBR twisting...
I'll double check it--this thing is scary to ride at speed right now.
Re: EBR twisting...
Axle is straight as an arrow....It is just the flex of the lower half/brace that is causing it. I'm going to tear it down and re-install again tomorrow to try and find the cause. It gets SCARY after 20mph.
Re: EBR twisting...
EBR's may not be great but you really think they're bending at 20 MPH? It sounds like your bearings aren't straight or the head tube is cracked. Did you check the torque on the lower clamp of the triple tree?
Re: EBR twisting...
It is hard to explain....The lower tubes (that hold the spring) allow the entire tree to turn .5" when pressure is applied making the entire front end move a lil and causing pseudo-tank-slap (back and forth). It is flexing at the fender brace-fork brace.
Re: EBR twisting...
Maybe put each fork on a bathroom scale and push the fork against the scale a prescribed number of inches of travel. Then check the other fork and compare the lbs readout on the scale. All of which to determine if springs have an unequal tension. I haven't read this whole thread through so excuse me if this has already been discussed
Re: EBR twisting...
Spring tension doesn't enter into this I'm pretty sure--it's a matter of flexing at the brace/axle area.
Re: EBR twisting...
I coaxed the brace to mount outside the tabs--Helped quite a bit. One side of the forks (right side) does move a bit more freely than the other...I dunno WTF that means, but overall drivability is a tad better.
Re: EBR twisting...
Try this.
Remove the wheel.
Loosen but don't remove the big nut and the 2 bolts that hold the top triple plate on.
Then loosen the pinch bolts that hold the forks into the lower triple tree.
Reinstall the wheel and tighten the axle nuts back down
Tighten the two bolts and the nut that hold the top triple plate.
Tighten the pinch bolts on the lower triple.
Both my ebr's and my friends were not right from the factory. One of the legs was pulled down a tiny bit more than the other causing all sorts of alignment issues with the front wheel.
If that dose not fix it I would guess that it might very well be your axle (how did you check it). Only way to be sure is to remove everything from it and then put it onto a flat surface and roll it back and forth looking for any part that is out of true.
Re: EBR twisting...
I removed everything from the axle--was fine.
One of the legs (right side) was loose/sloppier than the other--I did a similar re-tightening of all the bolts and it seemed to help. I might go back through it and try again using your method to the T. Overall, it isn't as bad as it was, but it is not perfect yet.
