Re: [RBW] An even fatter (F)atlantis!

My experience on this front is limited to touring on a Surly LHT which
mimics the Atlantis geometry in many regards. The Atlantis is said to have
been the inspiration for the LHT, so I don't think my observations will be
too off topic.

That having been said - while I realize that all Riv (and Riv
inspiredgeometries), can be described as rear biased, I find that my LHT
does quite well with front loads only - even on steep climbs. I tend to
load my front panniers first and put the lighter stuff like sleep pad and
sleeping bag) on the back. There's definately a balance that needs to be
struck with full loads, but I do my s240's with a front loaded bias and
have encountered very little front end instability when doing so.

Give it a try!

 I'd like to hear more about this too -- that is, to be clear, about the
 tendency of bikes to wander badly when climbing. I found the Sam Hillborne
 in particular to be very liable to this with a rear load, even compared to
 the 4 other Rivs I've owned. I'm very surprised at the number of Rivendell
 models pictured with huge baskets on the front. Does the front weight
 actually help the wandering? If I had put weight on the Sam Hill in front
 low riders, would things have been better? (I thought of doing this only
 after I sold the bike.)

 I've carried up to ~5 lb on my errand custom on a TA rack in front, and
 handling has been OK but I could feel it trying to take control of the
 front end. But that weight sat above the front fender.

 Well, to be clear I don't have any weight on the rack right now. What I
 am referring to is the tendency of some bikes on ascents to have the wheel
 wander rather than maintain a straight line. One then makes minute steering
 corrections to counter this. While I have zero experiences with bikes with
 low trail front end geometry, I have read people stating that one advantage
 of such frames is that they require less effort to remain straight while
 climbing (especially while tired). Given that I live in the mountains,
 every ride involves multiple climbs and I have been thinking about it
 lately.
 This article calls it weaving as a result of high wheel flop.

 So I was wondering if the weight when placed on the small front rack
 would affect this tendency or be unnoticed.

[RBW] An even fatter (F)atlantis!

That is a fabulous looking Atlantis.  Thanks for sharing the detailed photos, 
too.
