Re: [RBW] 650b Atlantis Sizing for an 85PBH

Hi Alex, I am not sure if you have checked the pbh chart at Riv's website. Based on the pbh chart, it looks like a 53 MIT Atlantis would best fit a 85 cm pbh. It is perfectly in the middle of the range from 83 to 87 cm pbh. https://www.rivbike.com/pages/pubic-bone-height-how-to-measure-your-pbh

[RBW] 650b Atlantis Sizing for an 85PBH

Hey all. I know Atlantis sizing is a hot topic around these parts. At the risk of being redundant, I am trying to figure out which Atlantis is the one for me. I recently bought a 56cm Atlantis 650b frame from the RBW Garage Sale, thinking that it was the perfect size for me. Now that I am

Re: [RBW] 650b Atlantis Pic on the BLUG

Ended up doing the conversion. Running 2.25 inch Thunder Burts the B.B. height is about 11 inches. That’s maybe half an inch lower than I was used to (700c x 48mm), but still plenty of clearance for the rough roads and loaded touring I use it for. -- You received this message because you are

Re: [RBW] 650b Atlantis Pic on the BLUG

Paul Moto-Lites work. I played with the conversion on my 53 Atlantis a couple of years ago. It was successful but short lived. I didn’t care for the change in height so went back to the 26”/canti configuration and that’s where it is today. Regards, Richard -- You received this message

Re: [RBW] 650b Atlantis Pic on the BLUG

I just can't see 650b presenting anything but good things, then! FWIW, I used to follow the Surly Groups page and there was a fellow who had bought a 700c Disc Trucker. He had a 559 wheelset and a 622 wheelset and changed them depending on the task. 622 for commuting and 559 for carrying a

Re: [RBW] 650b Atlantis Pic on the BLUG

This is exciting. I have a 650b Atlantis on order. My semi secret plan (I'm aware it's somewhat apocryphal) was to get a disc fork made for it down the line and keep v's or canti's in the rear. I'd Keep the og fork as is in case the change is dumb. Right now that seems about as close to dream

Joe, I think the Crust Romanceur is the closest you can get to a Disc Atlantis. Here is their description from their site. $1275 f/f. I have been looking at this and the new VO Polyvalent 650b as a disc option. The new Polyvalent will be out in the spring at $725 f/f. The Romanceür frame

Re: [RBW] 650b Atlantis Pic on the BLUG

Bill: Not that I'm likely to try this notion, but it would seem as long as you used a 650b tire that yielded the same OD as the 700c it replaced, the BB would not drop. 622 - 584 = 38 mm. Granted, that's a substantial increase in tire size, and most Atlantans are probable running something

If you had an older Atlantis that was a 56 or under, ie, a 26"-wheeled bike, you could use the Paul Motolites and run it as a 650b (if I ever run across a cheap 56 Atlantis, I'd consider doing such). I wouldn't try to run a 700c Atlantis as a 650b. (Realize, I have to caveat things everytime

Re: [RBW] 650b Atlantis Pic on the BLUG

If you have a 650b bike with cantilever studs, all you need to do is use Paul Motolite linear brakes, you can run 650b, 700c, and probably even the old 27". As the wheel diameter gets larger, the tire gets narrower due to frame and fork clearance, but the brakes can be adapted to a huge range

Re: [RBW] 650b Atlantis Pic on the BLUG

I did a short ride on a 56 cm 650b Atlantis at RBWHQ, and really liked it. I have a 58 cm 700c Atlantis, and the 650b was different somehow, in a good way. I can't put my finger on it but the ride was just nicer. I believe the new designs have slightly longer chainstays, so that may be part

Re: [RBW] 650b Atlantis Pic on the BLUG

Right, I forgot to mention that it is already running disc brakes so moving the studs won’t be an issue. If I had a set of 650b wheels sitting around I’d throw them on but in lieu of that I was hoping someone else might already have tried (whether by moving the studs or some other method). On Mon,

Re: [RBW] 650b Atlantis Pic on the BLUG

The canti posts are the issue. It would certainly be possible to move the posts to the 650b position and use brakes with enough adjustment to accommodate either 650b wheels or 700c. But, the costs of moving the posts and dealing with painting the frame and fork afterwards would be significant.

Perhaps the longer stays help? I know that my 2 later customs, with 44.5 cm stays, handle much better than the shorter stayed '95 custom (~42.5) and even than the Ram (43.5). And this despite what some would say are less than optimal wheels -- ranging in size from 24" to 25" depending on tire,

It's a 54, and it's essentially perfect. I'll keep it and be happy. Id, I think, fit a 56 a little better and I'm a fan of smaller wheels, aesthetically. That's all. Zero complaints about my hunq though. -- You received this message because you are subscribed to the Google Groups "RBW Owners
