More U.P. info - Geometry

Gerard Vroomen - 27-Apr-2015
As promised in the last blog about the six most commonly asked questions about the U.P., here is the info on its geometry:



Keep in mind that the seattube is designed to be offset, so that your seatpost doesn't have to be. This saves a bit of weight. It also means that the toptube length appears a bit longer than the frame really is, yet another reason why toptube length is a bad measurement to rely on. Best to check stack and reach for that. 

As you can see, the chainstays are quite short for a cross/gravel bike, despite the ability to fit the massive 55mm tires in. That's one of the benefits of the dropped drive-side chainstay.

If you have any questions about the geometry or would like me to give you advice on which size would best fit you, just go ahead and ask in the comments below or shoot me an email.

If you want to make sure you get all the info on the U.P. as it is released, be sure to subscribe via the orange box on the top right of this page. I'll say it again, don't rely on Facebook to hear about our releases, because those are designed to make you miss most of our posts unless we pay them, and we don't want to pay them to reach people who have already indicated they want to hear from us. Twitter is also not that effective but that's another story.

Comments & Questions

I hope you can advise me on frame size. It seems a S or M would be the size for me. I currently ride an Argon 18 Gallium Pro size S. Reach is 39 and ETT is 54. It fits me pretty well, but anything larger would not be good. Going on ETT for the UP seems like I would need a S, but going by reach a M.

I do NOT like a short stem, so wanted to let you know that.

Thanks!

Could you tell me what the seat tube length is on the L and XL? Also, could you tell me the wheelbase length for the L and XL?
Thanks

Hi Guys,
I am considering an Open UP for my wife. She is 5’2” and rides a standard 47-49cm road bike (ie. 47 Trek Emonda or 49 SWorks Crux). Would your small frame work for her? Based on your comments, I guess I should measure the stack on her existing bikes and use that number instead of top tube length. I assume you measure stack by dropping a plumb line to the centre of the BB then measure the distance from the line to the centre of the head tube?
I have two of your bikes and love them! Keep doing great things, guys.
Best,
John

The 47cm Emonda has the exact same stack as our Small frame, but a 4mm longer reach. That's very little, but that means the Small UP is actually a hair smaller than the Emonda she has now.

I am considering purchasing the U.P. for an upcoming race. I am between sizes M and L, it seems, at 5’11”. Any suggestions? I primarily ride mountain bikes and currently have a Yeti SB5 in size large with a shorter stem, if that helps. Thanks.

Hi Justin, I would recommend a fit by one of our retailers, but based on your info I would think almost certainly you're a size Large.

Hi Rob, for some reason no record of any incoming emails from that email address. Are you using the contact form on the left? Not sure what your question is so I can't answer it here either.

Trail on the Large would also be appreciated. I guess it kinda' depends on tire diameter.

I hope you can advise me on fram size for the Open U.P.P.E.R. - I'm 5'9 1/2" (69 1/2") tall. 30" inseam, 25 1/2" Torso. I own a Medium Trek 9.9 Farley fat bike- Perfect fit. Pinarello Dogma F8-55cm-Perfect fit.
The Open U.P.P.E.R Medium range is showing a rider height of 5'7"-5'11" on the geometry, but most of the numbers on the geometry are coming in smaller than my F8 Dogma 55cm Rim Brake Road Bike. Between a Medium or Large UPPER. Likely could be the layout of a Gravel/Road combo bike vs pure road, but I need a more expert opinion.

Only concerns are the tightness of trapezoids if too scrunched on the riding position (bike fit eliminated this on my Dogma F8), and toe friction with the front tire when turning sharply (especially when running 40mm gravel tires).
I've only had this happen on my "too small for me" 53 cm Ridley XCross.

Hello, I am 198 cm tall with an inseam of 98 cm, love the OPEN U.P.P.E.R. would you say it could be a bike for me? Would the bike be a fit?

thank you,

Hi Leo, the UPPER may be a good choice, but you should also take a look at the WIDE. At your height, the extra headtube length could be a good option. If you want, you can contact me (form on the left) with your current bike model, size and stem length & spacers underneath.

Can you please recommend a frame size for me. I currently ride a 2018 Niner RLT 9 Steel size 56. When I got that frame I was in between sizes 53 and 56. Now I would have preferred the 53.

Why do you feel the 56cm RLT9 is too big? Is it too high (can't get the bars low enough)? Is it too long (stem needs to be too short to compensate)? Best to reply using the Contact form on the left of this page.

Hi Gerard, I used to own a Cervélo R3 2007. Lovely bike. Great ride. I’m looking for something more versatile. Road, trails and light MTB. UP or Wide? The 51cm was a good fit with a long stem; I’m 173cm with a 74cm inseam. The Medium looks right on the chart in terms of height but I’m almost at the upper end of the Small; what would you recommend? Thank you.

Hi Gerrard,
Need a little help choosing M or L for my WIDE. All my road race bikes are S-Works (Tarmac, Venge and Shiv TT) size 54 (Team Specialized rider, 13X paracycling World Champion and Rio Games Gold medalist, BC EPIC 1000 record holder) but my previous Gravel race bike was 56 (2019 Diverge) and fit me well. I'm 178cm tall but long legs, shorter torso (my saddle height centre BB to top of saddle is 77.3cm). I'm sure I could make a M or L fit but which would you recommend?

Hi Tristen, well, the road bikes point towards the M, the Diverge points towards the L. Given that the Diverge is closer to how you're going to use the WIDE, I would say the Large (and in general, the L with a shorter stem will probably behave a bit nicer for you on tough off-road stuff than the medium with a larger stem. And on-road the difference isn't that significant.
