I guess another question would be can you expect steering to be twitchy when all your leverage it behind the steering axis instead of in front like you find on all drop bar bikes? On Sunday, September 10, 2023 at 1:59:17 PM UTC-7 eddietheflay wrote: > I am considering a Roadini and not sure if

Your second question is, I think, where things stand. I've ridden lots of upright bars with varying stem lengths and there isn't much difference in steering feel, they all have a bit of what the recumbent folks call tiller effect. I try to buy frames that give me good reach to Boscos without ne

Of course it might be worse on your current bike than any Rivendell. I have an old/cheap Marin hybrid with Boscos and the nervous/tiller effect on that one is kinda ridiculous, Rivs don't act like that. On Sunday, September 10, 2023 at 2:19:39 PM UTC-7 Joe Bernard wrote: > Your second question

Eddie, for what it's worth: when I bought an old Atlantis (that has the much more compact size and geometry than current Atlantis models) it had a Noodle drop bar on a medium length stem — a pretty standard Rivendell build. I couldn't ride it for more than a few miles without experiencing terri

Wow. All I can say is that the steering is not at all twitchy on either my Clem or Gus, both with Bosco’s. Clem has a 135 stem, Gus 100. It has been a long time since I rode drop bars but compared to my mtb’s with relatively straight bars with short stems, the Riv’s under steer a little bit. But ot

So Joe I understand the concept of tiller as in the olden days a did a couple of years on bents. My more specific question is if a bike has a shorter top tube which requires more stem length to "reach" proper reach, then does some of the tiller affect get reduced? On Sunday, September 10, 2023

Well Eddie there are cans of worms and then there are #10 can of worms , and this is a whole case of them ! First off, the amount of sensitivity in steering inputs, that feeling, largely depends on the design of the frame. I've had two bike set up as identical as they can be with Albatross ba

More specifically Eddie, I don't think using a bar like the Billie on a Roadini is a good idea to begin with if you find yourself wanting to move forward for a more stable steering experience. You be much better of with a shallow drop bar. Personally, I don't think having high bars lives up to

I need my bars quite high cuz I'm old and my neck aches badly when my head is hanging over drop bars. I have considered tall stem and drop bars. I guess that would mean shorter top-tubed bike in order to make the reach to the hoods on drop bars comfortable. On Monday, September 11, 2023 at 5:17

Eddie, When I first rode a Clem with Bosco bars it was so different from drop bars below the saddle level that steering seemed odd. It took a few rides to settle in to the upright position and having the bars above the saddle and coming back toward me, if that makes sense. Like you though I was

I have never tried really high-mounted drop bars like these ones: http://lovelybike.blogspot.com/2010/05/drop-bar-diaries.html And for me that would be mostly about the aesthetics. Swept back bars look cooler and less weird that high-mounted drop bars. I wonder if the steering would "seem" signi

Doug, my guess is that headtube angle and trail on the Clem probably adds to steadier steering. Riv does not seem to publish trail numbers but as I understand it trail is key to steering characteristics. On Monday, September 11, 2023 at 5:47:46 AM UTC-7 Doug H. wrote: > I do wonder if the long

In your original post you refer to your "current bike" with Billie bars. Is that the Curtlo that you are selling over on the iBob list? If so, for the benefit of the commenters, you said that Curtlo was designed to emulate a Rambouillet. I've got two comments: First, I'm not crazy about y
