Is there such a thing as an integrated handlebars and stem with a positive stem rise?

Recently got a bike fit with the following geometry:

Handlebar width: 42
Handlebar reach: 80
Stem length: 80
Stem rise: 7 degree

Curious if there are integrated bar and stems on the market that have these dimensions.

Thanks!

Euhm are u sure its rise? Because you can just add spacers to get the correct height.

Sounds like you’re trying to get the best fit on a frame that is too low at the front.

Rise would normally be expressed in degrees, not percent. With integrated bars, most are -6 to -10 and rarely are there angle options. If you can't make that work with spacers, you've got the wrong frame or a bad fit. I'm 168cm tall and use a 10cm saddle to bar drop. My bars are -7 and I use the 10mm headset cover, plus one 10mm spacer. 110mm stem length and 80mm bar reach. I'd be banging my knees on the bar when standing with an 80mm stem length.

It sounds like the output from your bike fit was not entirely helpful in practice.

Stem rise/drop is not expressed in percent, but in degrees. This allows your intrepid bike fitter to use the head angle of your chosen frame and the recommended stem length to provide you with a rise/drop in percent. For an integrated bar this will need to be looked at together with the bar's reach.

The stack of your chosen frame, including spacers, can be used to find a suitable integrated bar. If in fact your chosen frame is too low, even once you add spacers, then you need a separate bar and stem. You'll need to invert the stem to get a positive stem angle. It may not look good, although I do see plenty of people ride like that, so it's nothing to be ashamed of. Otherwise, you'll need to get more flexible.

Most everyone is riding with an upward stem angle:

Assuming most headtube angles are around 73 degrees, you would need a minus 17 degree stem
in order to have a flat stem...

A slope (rise) of 7% means an angle of 4 degree just FYI. But I guess it's a typo.

Yeah sounds like rise (from horizontal). What would be helpful to know is the head tube angle to calculate wich degree would be spot on. Lots of modern small bikes have 71 degrees, taller ones, yes, around 72-73.

Sorry for the confusion, was meant to be 7degrees (not percent) rise.

Just wondering if there is an integrated or semi integrated handlebars that have a rise instead of being flat or negative.

A +7deg 80mm stem is the same as a -7deg 80mm stem + 20mm in spacers.

If you can't add 20mm in spacers, then you goofed somewhere down the line.

Also hardly anyone makes integrated barstems with the equivalent of an 80mm stem and 80mm reach bars. You might find a 90mm stem, 70mm reach barstem combo though. You certainly won't find one with a positive rise...that's not the target market.

Hmmm...when your b/f result calls for a total reach of 160mm and 7° rise (assume that's on top of your current spacer stack), I'd say
- the current bike is on the edge if being too long (long reach)
- the current bike might be (depending on current spacer stack) too low/aggressive (low stack).
What bike is it that you have been fitted on and what spacers are installed? Asking as looking for a different bike/frame might be a smarter option...

Cheers

Since the majority of stems have a 7 degree rise, would that not be the case with integrated bar/stems?

Maybe I misunderstood - but aren't those stems MINUS 7° and the OP is looking for an integrated b/stem with PLUS 7°???

With stems, you just flip it. Most are used as -7, not +7. With one piece bar/stem the bars would be upside down. It's apparently not practical to make both plus and minus models.
