I've always struggled to find bars that don't make it feel as though my elbows are trying to join at my spine, and that I'd be more comfortable riding with a broom handle instead!

Any thoughts as to what's going on?

Suspect it’s primarily for descending - off the back of the saddle and swept bars still allow for a decent reach and control. Proper XC race bikes still often have straight bars.

You can get bars of any size or sweep, try chain reaction.

Excellent! biggrin

You won't mind pointing some out to me then, given that there's no filter for backsweep and every single bloody pair I've just looked at ranges between 6 to 9 degrees of sweep?

Could you get a longer stem to move the bars away from you?

Maybe moving your saddle further away might help too.

I've always just rotated my MTB bars forward so the 'sweep' is upwards rather than towards the saddle

So, to answer q1, the reason why they all sweep backwards is for comfort.

Quite why you’re not comfortable, I cannot hazard a guess at without seeing you on the bike.

Q2: straight ‘broomhandle’ bars are available from Origin8, who sell on Amazon. The fixie crowd love ‘em.

I don't think it's the reach, as in every other way they feel right. I just feel as though comfort would be achieved with the bars fully perpendicular to my direction of travel, and any sweep back from that reduces the comfort.

With your wrist relaxed, make a fist as though holding a bar - taking a straight line through your forearm, look at the angle the bar would be - it's not perpendicular

To make the angle perpendicular you'll need to rotate your hand inwards. Then you have a straight line going down the outside of your forearm and along your hand - this isn't a natural position and will put strain on the outside of your wrist which may become ucomfortable over the duration of a ride.

This is general of course, your wrists indeed favour a more straight bar.

I just tried that... If anything, I reckon I need a forwards sweep! hehe

How about wider bars then? As your hand get wider apart the sweep will make more sense.

3T do a 3 degree sweep flat bar, 720mm wide, there may be others, doubt you'll find less than 3 degrees. It sounds like you have very unusual biomechanics!

Ok like that is it?
Well show us a picture of what you have then as we are not psychic.
If you know you want a straight bar just buy an XC bar, as they use straight bars to get their weight as far over the front wheel as possible. But that is not neccessarily allowing for comfort.

Here, did you look at the UKs largest online retailer?

You may also need someone to help you get your riding position sorted if you feel like your elbows are in your sides. Personally it sounds like your bars are not wide enough.

I looked at the UK's largest online reseller, but I rather suspect you didn't, as none of the bars you've linked to have zero sweep. If I could go on to CRC and easily find zero sweep handlebars, I would've done. Flat bars are easy to find, but I'm not necessarily looking for flat bars...

The bars I currently have are 785mm wide Race Face SixC carbon bars which have an 8 degree back sweep.

So what do you want?
Same bar but less sweep?
How much less? 1, 3, 5?
Give us a clue and we can go look for you?

Well 5 degrees looks the shallowest.
Turns out zero degrees is actually bad for your wrists and not ergonomic at all which is probably why you are struggling.
Go wider maybe.
If not, have fun finding what you want.

Here you go op, job done



Seriously though I have tried using a broomstick for a laugh and it was bdly uncomfortable. That's most likely why nobody makes a bar like that.

The same bars would be fine worth a little sweep as possible, but I've not got orangutan arms, so there must be something else going on with my riding position.

I just seem to naturally gravitate to having my forearms pointing straight forwards, which then means my wrists are bent unnaturally with a rearward sweep on the bars.

Tried a shorter stem to bring the bars towards you a bit?
