Re: [RBW] Re: loaded handling question
Seems like getting the load down as low as possible will be the best option. Low riders in the front for heavier loads, a small saddle bag and front bag for lighter items. The IRD headset will help as well. But even with all of the above you may still get some shimmy. Sometimes you may have to stop and rearrange things in your bags for better balance. Unless you have a really stiff bike riding with one pannier is a sure way to cause shimmy. One of the good things about the bikepacking frame bags is it puts weight lower and centered, so those are options too. ~mike > -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

Re: [RBW] Re: loaded handling question
I want to reiterate that my bike bike rides rock-solid at any speed hands free. I can corner on it, change lanes, whatever and am fine. It's just adding S240 weight to it that it freaks out. Hopefully that can be mitigated if not eliminated with some simple changes in set up and/or packing technique! On Sun, May 31, 2015 at 9:47 PM, 'hangtownmatt' via RBW Owners Bunch wrote: > Wow!

Re: [RBW] Re: loaded handling question
I'm preferring to work with what I got, and if I just improve it I'll be happy. But if nothing works, open to upgrades.

Re: [RBW] Re: loaded handling question
I'm going to fool around with some different dry-run set up ups and see how it goes. Rear bag only, rear bag w/ small front load, rear panniers only, and rear pannies with just a little up front. Also going to try the saddle a bit forward and see if that does anything. Hands free isn't the ultimate goal, as I'll settle for steady and smooth!

Re: [RBW] Re: loaded handling question
Sure, definitely try some different loading strategies with panniers, but I think other posters area too quick to dismiss a big saddlebag. It's the only rear load that doesn't have leverage on the rear triangle (as long as it's mostly hanging from the saddle, with any rack or support just providing a little stability). As shown above, it's the only way I've found to carry a 30+/- lb load on a Riv similar to David's and still be able to ride shimmy free, including the all important to some of us no hands. Second best had been the big saddlebag plus front low riders. Rear rack loads even by themselves don't work for me on this bike.

Re: [RBW] Re: loaded handling question
I'm not upset if I can't ride no hands, laden or not; it's just a minor annoyance. But no, the two are not exclusive. My '94 rode rock solid and rock steady no-hands at 8 mph and at 18 mph with 30 lb in an unsupported Camper Longflap; and the '94 was quicker handling than the later ones, with 42.4 cm stays. (Fly rack.) The Ram was almost as stable; Fly. The '73 Motobecane: again, stable, no shimmy, Fly; and this with a flexy frame. The '03, less so -- perhaps because the rack is custom and not Tubus? That said, the '94, like the '03 would shimmy from time to time, but not regularly under heavy rear load; I know that when I switched from 26 X 1" Turbos to 26 X 1.35" Kojaks, the '03 started to shimmy (no load as well as loads of varying weights, rear).

Re: [RBW] Re: loaded handling question
As an inveterate rear-loader, of several Rivendells ('94 Road, '03 Road,
Sam Hill) and many other bikes, I haven't found that rear loads even up to
40 lb cause shimmy, while even modest front loads -- over 5 but no more
than 10 lb -- make the front wheels harder to control.
Perhaps shimmy associated with rear loads may be caused by flexing racks? I
