ProsSimple, solid & well made
Allows fitting standard Ortlieb (or similar) bar-bag mount to an ebike, and sits the bar-bag slightly lower than when fixed to the handlebar.

In my case, the fixing cable for the bar-bag mount seemed to be interfering with the console on my ebike, meaning the console wouldn’t always turn on the ebike electrics (a sort-of known but not understood problem with Bosch Intuvia consoles). Solved by using one of these Thorn mounts, and attaching the bag mount to it instead of to the handlebar. Fitting was simple – remove headset spacers and insert accessory bar.

ConsNot available in the U.S. Direct - :)
ProsTough, small, well designed
Quality is great - purchased for use in the United States
As cyclists in the U.S. are not as savvy as those outside of U.S., or as common. Making use of every inch of a bicycle is unusual. This item fits this need , works well on both the seat post as well as the handlebar.
Well constructed and tough, but at the same time light.
I have only had this for a day, originally intended to use on the handlebar, but found it not to be long enough for my needs
I have placed this on the seat post to hold lights and other gear and it is working well. Have ordered one of its big brothers and expect this will be better fitting for my bag size on my handlebar.
Perfect

This is just what I needed to lower a handlebar bag. Light, strong and well-made. Looks like it will last a long time.

ConsDifferent clamps sizes would be nice. Had to custom make a shim to fit my 22.2mm stem.
ProsSolid build quality and still light weight
I have a 31.8mm carbon fiber bullhorn handlebar and used this Thorn Accessory bar to mount my trigger shifters on to the stem bellow it, since most shifters wont mount to a handlebar that thick. I hope these become more available to the states.
High Quality Product

Conslateral tube too far away from fork tube
Prosperfect fit, high quality
The bar is to far away from the fork tube for my intended purpose. I bought ist tomount a rohloff shifting grip, and the lateral tube is too near under my race handlebar for easy turning by the hand. So I cut it off and welded it on the tube that is shifted over the fork tube.
Works perfect now - yes, I know that not all peopla are able to weld aluminum ...

ConsNone
ProsNeat, strong
Bought to use for fitting a handlebar bag as my handlebars are not a good shape for the bag and it kept slipping. This bar is excellent, does the job perfectly, holds my bag in a good position. Small and neat and non obtrusive.

ConsPrice
ProsRobust, not heavy, steerer tube mounting
Expensive for a bit of bent metal but sitting as it does on the steerer tube is far more robust than something sitting off the handlebars. My handlebars are full of stuff (more like the flight deck of the USS Enterprise). My initial use for this thing is to mount a light, but I will undoubtedly find a use for the remaining space!

ConsCan't think of any
ProsWell made, compact
Purchased to mount our big bar bag from Arkel. We were unable to mount the bag on our moustache handlebars on the front of our tandem. This device solved the problem! I had to order it from the UK as I could not locate a vendor in the US. Received in within 2 weeks, much to my surprise.

ConsMy barbag is just a little harder to access when pedalling along.
Proskeeps my bar bag away from the cables. Keeps the handlebars uncluttered.
Bought to carry my Ortlieb barbag. I previously used a Minoura Swinggrip which eventually fell apart. The advantage of this device is that it keeps your bars clear and uncluttered. It also places the bar bag further away from the brake and gear cables. Using the Ortlieb mounting bracket on my handlebars, the bar bag had a tendency to kink the cables thereby affecting performance of the gears. It doesn't become a nuisance like the swingbar when upending the bike for maintenance or get knocked and damaged like a swingbar.

The downside is that the bar bag is just a little further away for access on the move.

Could I add clip on aerobars to this?
By
14 Mar 2024
Primary use is bike packing, looking for comfort position not aero.
While we have not tried it, it is a possibility, normally it is used to mount bar bags or similar. SK 15/03/24
What is the torque specification on the tightening bolt?
By
09 Oct 2020
I just ordered a second Thord accessory bar after stripping out the threads from over-tightening the bolt. What is the recommended torque spec for the bolt? Thank you.
Hello, we would recommend tightening this to the same torque as your using on either or stem or seat clamp depending on the location of where you are clamping.

Can this be mounted to the head tube (not steering tube) of an Electra Townie?
By
05 Feb 2020
I think it is a standard size head tube for a standard size steering tube, 1 1/8
Hi, no. This will only fit onto a 1 1/8 steerer tube. It replaces some of the steerer tube spacers. Thanks 06/02/20

Hi, can I mount this to a 27.2mm seatpost?
By
02 Jan 2020
Would I need a shim to mount it to a 27.2mm seatpost? If yes, do can you provide it? How do I add to the order?
Hi,

Mounts to 1 1/8inch steerer tube - this is 28.6mm so you need a shim such as - SJS Cycles part number : 32254D286

Thanks - 03/01/20
What is the weight limit on this?
By
17 Jun 2019
Could I use this to mount aero bars at the top of the steerer tube?
Our guidance is 5kg. We definitely would NOT use this for anything other than a bar bag/lights/shifters.

Thanks - 17/06/19
My grip shifter fits on a 21mm bar will it fit on this?
By
16 Feb 2019
I've a grip shifter on a 21(ish) mm flat bar and I'm hoping it'll fit on this. What's the diameter of the "stick"? Also what diameter will the clamp fit on?
As advertised the extension bar is 22.2mm in diameter, and the steerer tube clamp fits 1.1/8th inch steerer tubes.

We cannot confirm that your shifter will fit, a more specific measurement than 21(ish) mm would be required

Can I mount this (or a similar product) to my seat post for the use of 2 rear lights?
By
08 Mar 2018
I have a large rear mudguard & saddle bag which both obscure any lights which have been previously fitted to my seat post. I am looking for a product like this which would allow me to mount 2 lights to my seat post (1 either side of my mudguard & saddle bag) so that they are not obscured & visible to traffic behind me.
Hi there,

Yes this could be fitted to a seatpost, as long as the size is 28.5mm or less.

Thanks
Please, Does This Accessory T-Bar Include End-Caps? It Is A Bit Hard To Tell From The Photo. Thanks.

Hi,

This accessory bar does have end caps.

Thanks.
Do You Have A Shim To Use This Bar With A 22.2Mm Quill?
By
31 May 2016
Nitto Technomic quill
Hi,

We don't have a shim that will cover the full distance from 22.2mm up to 28.6 for this accessory bar. We could offer two shims, but this may limit how well it can grip the stem and it may be able to move.

Thanks.
Is This Strong Enough To Mount A Bar Bag On?

Hi,

Yes this Accessory T Bar should be more than strong enough to hold the weight of a bar bag.

Thanks.
Thorn Accessory Bar T Shaped 55 Mm Ext + Canti Brakes?
By
11 Dec 2013
Morning
Am thinking about getting one of these to fit a shifter for a hub gear with drop bars. Will this interfere with cantilver brakes and the front cable hanger?

Thanks
Hi,

It is possible it will interfere with the brakes or front cable hanger. But this all depends on where you have it mounted and what position you mount it in, without knowing how you have your bike set up with spacers ETC I can't say for definite if it will work or not I'm afraid.

Thanks.
