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.

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 Gerard. Seriously considering an UP but a bit unsure if I’ll be too big. I’m 195 cm with a 90 cm inseam and usually ride a 61cm bike (TCR sl and ad 61r fairlight strael both of which have a fairly similar stack and reach). Would the XL UP work for me? Both my other bikes work well for me with a few spacers under the bars. Thanks

Hi Laurence, should be no problem, the UP in XL would require approx. 1cm less in spacers than the TCR to get the same bar height. And probably the same stem length as you have on the TCR now, assuming you will use the UP for serious gravel riding. Or you could lengthen the stem by 5-10mm and be very close to the current setup.

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.

Sorry for the awkward reply well after your post - but did you get the Up for your wife? How did she find the standover? I'm 5'3" but my inseam is 28.6" (or 727mm). The published standover for the small is 743, so a hair too tall. That's without any shoes though. I just discovered this bike as I was starting my gravel search.

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.

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.

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?

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.

Hi and congratulations for a original project make with the heart and may be the best frame for start the perfect bike .Teo years ago I bought a Scott Addict 10 gravel ,Very lite but now I am upgrade wheels ,cranks etc etc.But I think that the Scott frame is not worthy for Schmolke Enve Ax lightness Extralite ........Call me freak if you like hehe .
I am decided to buy one U.P.P.E.R
The question of the century :the size ¡¡¡¡¡¡¡in Scoot its 54 or M but to be honest the seat post are 25 mm offset what for mi sit bone stay correct and the stem its 100 6 degrees and the most important the size :
I am 1,78 and my legs 84. in the 10 of may I make a biomechanics study .I can wait or your recommended m or l that I am just in the middle

Tough to say. The Scott is similar to our Medium, but if you say it doesn't fit well, then of course it's hard to predict if maybe you're not better off on a Large. The fitting on May 10 should be able to give you clarity on that. Best of luck!

Hi Gerard. I currently ride a 2016 58cm Santa Cruz Stigmata. I'm interested in moving to an Open U.P., but I'm a little confused about whether a Large or XL would fit better. My Stigmata has a stack of 598.1 and a reach of 392. I run a 100mm stem with 3cm between the bottom of the stem and top of the head tube. It's a moderately aggressive position.

The Open U.P. XL is a stack of 604 and reach of 401, while the L is 580 and 387. The stack on the Large U.P. is low enough that I'm afraid it would be too aggressive or need a lot of spacers, while the reach on the XL would require me to run a 90mm stem.

Any recommendation? How would the XL handle with a 90mm stem? I'm planning to use the bike for a variety of purposes: gravel racing, bikepacking, sometimes a do-it-all bike with sets of of road and gravel wheels when I travel. Thanks for your help.

Hi there, definitely the XL. 90mm is quite normal on gravel, a little shorter than on your road bike will give you a bit more control off-road and not really make much of a difference on-road.

Hello! I am interested in the U.P. And UPPER for both road and gravel duty. I am wondering if it would be a good fit for my geo. I am 6’1”, 32” inseam, and my arms are 36” long (sleeve length on shirt). Will I be too stretched out? Comparing this to a Giant Revolt Advanced 0 in a M/L. Thanks!

OPEN
Hi John, the effective fit of the Revolt in M/L is the same as our frames in L. So with the same stem length, you'd get the same position as long as the spacers under the stem are matched to get the same bar height. In this case, the UP would require 9mm more spacers than the Revolt, the WIDE would require 11mm fewer spacers than the Revolt (or instead of spacers of course the stem angle could also be changed). So all of this is assuming using the same stem length. Given your body dimensions, the UP with a slightly lower headtube may be a better match for you than the Revolt or the WIDE.

Hope that helps,

Gerard,

Thank you for your reply! I see - compared to the Giant, given the same stem length, I would need 9mm spacers on the UP to maintain similar geo. However, as you say, given my dimensions, lowering my head tube slightly would do the same? I assume to lower the head tube would require adjusting the headset?
Post #38 of 52. Posted by John Burrow on 22-Jun-2021 06:29:30 GMT in reply to post #37 [23201<--23202]
OPEN
What I mean is that if you have the Giant with X spacers (let's say 14mm), then you can move ALL the parts over to the UP, add 9mm of spacers more, and you'd have the same position (so 23mm spacers in total. Likewise, if you would move your parts to the WIDE, then you would need to remove 11mm of spacers, so only 3mm left.

But I am assuming that you don't need a lot of spacers with your body dimensions, which means that maybe on the WIDE, you would like to go lower but you cannot (you can't go to negative spacers) and even on the Revolt, you may (or may not, hard for me to see from just these numbers) also want to go lower than you can on that frame.

As you say, the Medium would be the standard frame size for you unless you have a very specific position (very upright for example). But even then, the first choice would probably become the WIDE in Medium, not the UP in Large. Of course to look at this in all detail, a physical fit session would be better than an online one.

Hi Gerard-

I’m very interested in an Upper and it looks like from some similar questions below you would recommend an XL but I’m having a hard time since the size chart says it could fit someone up to 6-7. I’m 6-2, and ride a 58cm Cervelo R5 with a 110 Stem, no spacers and a zero offset post. I’ve always followed the logic to err on the small side since the first real bike I was sold was a 63cm Bianchi that the shop had in stock and wanted to sell. I could never make it fit but if you err on the small side you can lengthen the stem, raise the seat, etc. My planned use the for the bike is fast gravel riding and racing. Thanks!

Hi Justin, a 6'7 rider can fit or not, this all depends on if the position is aggressive or not. But it's an outlier and the size indication there is just a first idea, certainly not the final say when we fit people. The XL is very similar to most 58cm Cervelo's. On stack, it depends a bit on the generation of your R5, but it's normally close too (and you may want to sit a few mm higher for gravel than on pure road anyway).

I am seriously considering buying an OPEN Wide frame. Presently I am riding a Merdia Silex Small, Aluminum. I have become enamored with this style bicycle and geometry. They are not available in the USA, so I am looking at alternative frames. My local bike shops owner has an OPEN UP frame and is recommending them. I have a cyclocross background going back 30 yrs. If I buy an OPEN frame I am looking at a medium. I am 5 ft 9 in, 32+ inseam. I am not as agile and there are times with the Merida that I wish it was a Med. Appreciate your assistance. Cheers Erik

I’m trying to pick a frame bag for my Open U.P (XL size) but I won’t have the frame for another month.

Do you have the measurements for the inner triangle, including the head tube height as measured from inner triangle space?
