I'm thinking about buying one of these but looking at the geometry it looks unfeasibly long.
The large is longer than my large Signal. I'm 5'11, I think I might be better off on the medium.Â
Just wanted to pick the brains of owners before I go for it.
im seeing 455 on a large? that's quite short, that's a medium on most hardtails?
I'm assuming to allow for longer stems than the current crop of trail bikes
Â
or are you talking ETT?
608mm top tube on the large no?
I am 6' tall but with relatively short arms and legs (31" inseam) and ride a Large Broken Road.
Just measured it and it's 620mm from centre of head tube to centre of seat tube. I've got a 50mm stem on it and the distance from centre of the bar clamp to the nose of my saddle is 515mm.
Not sure if those measurements are any use to you but let me know if you need any more.

608mm top tube on the large no?
Â
No, doesn't look like it from the website geo.
Effective Top Tube is 642mm which sounds long for the reach, due to slack seat tube. The large signal is 634 (606 on the medium, is that where your 608 came from?)
Large is 455mm reach - I'd say that's short. The large signal is 465.
Height range for the large Broken Road is 5' 9" to 6' 2" so you look right in the range.

Ah right, sorry - TT wasn't shown as a red line on the bike image on their geo chart on the bike listing page, and isn't really a measurement I use. ETT gives a more useful measurement in my opinion.
Still, given reach and height range you look squarely in the Large to me and even that has a small reach compared to a lot of larges.
I'm 6' and all my hardtails have had a reach of 470-480 and ETT around 650-660.
This site is good for side by side comparisons;

This. I've looked at the Broken Road Ti in the past and been put off by the slack seat tube. If it was a straight seat tube 73 might be just about acceptable, but it's got a bend, so the higher the saddle the slacker the effective angle.
Is the geometry measured with fork at sag height or top-out?
I'd be using with a rigid fork.
