Whether Riv's listed TT's are actual or effective has varied a bit, but I think the recent pattern has been consistent: recently, it has been the case that the 6 degree bikes list effective TT's when they are in a chart. I remember an early Hillborne chart listing both actual and effective, but as far as I know, every time a 6 degree bike has been included in a chart, only one TT length has been listed, and there has been a little notice saying that if the TT angle is greater than 6 degrees, the listed TT is effective and not actual.

 

The Atlantis with its 2.5 degree TT slope always has had the listing as actual TT length.

Thanks for the research, Garth.  does anybody know how Rivendell usually cites their top tube measurements?  Actual or effective?   An actual 61cm top tube with a 6 degree slope and a 71 degree head tube would seem to be equivalent to about 62.86 cm (24 3/4") horizontal (effective) top tube.

(If it's shorter than your Bomba, and you already know that's your minimum, then I realize it probably won't work for you. Just wondering, mostly.) 

I'm kind of surprised it isn't longer.  I would have thought that a bike designed specifically to use the reach-back-toward-you Bosco bar would have been intentionally long.

  I had some questions about the Clem for Keven about the 59cm. Clem that he graciously answered for me and thought I'd pass them along .

1. The head/front end(top of the head tube) on the Clem is "virtually identical" in  height as my 60cm. Bombadil . 
2. The top tube is "61cm-ish" .  That's 2cm. shorter than the Bomba , :(  . (Too short for me,, boo-hoo , lol )
3. The head and seat angles he as not positive on, likely the same as the Bomba , which is a 72 ST and 71 HT.
4. In regards to number one, to get the highest bars, the steering tube is always left as long as possible !
5. The BB and headset are likely Tange's .
6. If you want a different front cable hanger, you can buy one separately for it .  I assume he meant the would install it in place of the stock one.


  And he welcomes questions, which is awesome !  ! 

Oh yes ...  he also added this : " Grant is making noise about creating a 64cm Clementine which would have a bigger headtube (higher handlebars) than your Bombadil and the 59cm Clem's, so that might be worth waiting for/ signing up for.  Not sure if it will be included with the first shipment."

So there just may be a 64cm Clementine !  Which I'd love as a top tube on a Clem would be close to my max clearance wise .  I always wanted a Betty or something like it in the past but it was always just not quite tall/long enough for me , so this solves all that :)  Yeah !
