Can you replace a 35mm bar with a 31.8?

[force11111]

As the title says. I have a turbo levo and the specs say it’s a 35mm diameter bar. I want to get a bar with slightly more rise but All the bars I’m looking at are 31.8mm. I don’t suppose that would be a direct replacement or do I have to replace the stem as well?

If that’s not doable does anyone have a link to a good 35mm riser bar/brand?

There are adapters, or you could get a new stem. If you haven't gotten bars yet, OneUp makes nice compliant bars that are a good value. I'd just get a new stem, though if you really need a 31.8, particularly if you need to get more rise than available in a bar.

Deity do 50mm riser bars in 35mm

 

[Mcharza]

Renthal also makes bars up to 40 mm rise.

Burgtec ride high 50mm

How high of rise does the stock handlebar have

 

[Polar]

35mm so if you want a appreciable rise you need at least 40mm.

Ok thanks. Ordered a 50mm riser bar from diety.

Are you already maxed out on spacers? Just curious, that looks like a good choice.

Sorry. I’m the noobiest noob in noobville. What do you mean Maxed on spacers? On the stem?

Why did you want change the rise of your bars in the first place? Spacers (shown in RED) adjust the placement/height of the stem which holds the bars on the steer tube. You may have extra spacers above the stem (you always need at least one spacer above the stem) which could be placed under the stem to get a little more height if that is what you are looking for.

If you are feeling too much pressure on your wrists maybe a bike fitting is a good idea as putting bars with TOO much rise can be difficult to ride.

Yeah, I swopped out my 35mm stem for a Hope 31.8 and put some enve bars on that I had spare.

Under the stem, on the part of the fork that comes up through the bike, there are circular spacers that can be used to raise or lower the level of the stem. That way you can adjust the height of the stem/bars just by adding or removing those spacers without changing anything else out.

It looks like there’s a spacer above the stem on my bike. So I guess I can still move it up

Probably not. You need at least one spacer above the stem. You might be able to buy two 5mm spacers and split the difference as long as there is still enough distance for the steer tube bolt to press down on the spacer on top of the stem.

As long as there's a gap, you don't need a spacer above the stem. If there's no gap, you do.

@force11111, I've replaced stems and bars on my ebikes a few times. While you can adjust stem height by using different spacers above and below (the stem) to your personal preference, always make sure to leave a ~3mm gap between top of steering tube and top cap.

It is also recommended to have a 5mm spacer above the stem and not to exceed ~50mm of spacers below the stem.

Take a look at the photo below. It should look like this.

Yep!

 

[CarolinaCrawler]

I know rockshox says to not use more than 30mm spacers under the stem due to leverage on the steering tube.

 

[Mosheas]

I changed to a 31.8 handlebar with rise 50 mm and stem adapter for 35 mm, excellent.

Remember that adding Spacers to increase your handlebar height will slightly reduce your reach Geometry.

 

[hilbil-E-bikr]

I used these last year to install a set of Renthal 31.8 bars I already had on my 35mm stem to get more rise. It was only going to be temporary but really like the way the bars ride so have left them on. I haven’t had any issues. YMMV

FUNN make a stem that will give you 10mm rise and it's available in various lengths as well. Look for FUNN Equalizer.

 

[Chairman]

Or you can fit some triple clamp forks which enable you to lower and raise the front end at will.

 

[Moshe]

Deity also makes a 35mm handlebar with an 80mm rise and an 800mm width. I use it on my Kenevo SL.
