Stack & Reach for Joe Appaloosa & Atlantis

[Den John]

Hello,

My name is Johnny. I live in Belgium and I'm Riv Curious. I post from time to time on the iBOB group.

I've been obsessed with the idea of owning a Riv for a while. I'm particularly interested in the Atlantis and Appaloosa.

Could anyone tell me the stack & reach numbers for a 55cm Atlantis and a 57cm Appaloosa (current models)? Riv doesn't list S&R on their geometry chart.

An image of the measurements I need is attached.

I'd like to use wide drop bars, so stack & reach are quite important to know.

If anyone has any comments on the current long chainstay versions of these bikes, I'd also be interested to hear. This seems to be the most distinctive aspect, and the only way to get something like this in the EU would be to go custom. I do have a bakfiets,

and the long wheelbase on that makes for a very nice ride.

I suppose now is not really the best time to think about importing a bike from the US to Europe, but never mind :-)

Thanks,

Johnny in Belgium

I have found bikeinsights to be wrong on both Stack and Reach for Rivendell bikes. They don't take into account the head-tube extension built into Riv's lugs.

I don't know if every model is wrong on Bike insights but when they skip the 20mm head-tube extension in the calculated values, the Stack would actually be 19mm higher and the reach 6mm Less.

[David Johnston]

I have also found on some of the older Rivendell models with 2°-3°
sloping top tubes Bike insights mixes up the effective top tube and
calls it the actual top tube and then calculates a longer effective
top tube.

No worries, I already spent a good few hours fiddling with the various models and options on there :-)

Ah, I was wonndering about that. Any idea how long those extensions generally are? I'm wondering if I can get away without a riser stem.

The current (2020) 57cm appaloosa is also 10mm longer in the toptube than the old (2017-2019) 58cm. This caught me offguard because they specifically stated that all measurements were the same when they are not. Bike insights is listing 61.5 TT when it is currently 62.5

And ignore my last post I was looking at the wrong tabs on my browser.
