ProsLooks good
Was to wide for my grandsons trailer bike so has to make adjustments to trailer arm to fit would recommend you measure trailer hook up and make sure it will fit other than that grandson very happy and gets all over on it

ProsWell made, easy fit, quick release,
We bought a second hand trailer bike for our 4 year old son & noticed that the hitch had seen better days and needed new insert sleeve to have a chance of fitting onto an adult bike. I really didn't think we would find a spare, so was thrilled when we did a search and it came up with the SJS cycles site & the ultimate hardware trailer bike spare hitch + 3 insert sleeves of different sizes. After fitting it onto my husbands cycle & it attaching perfectly to my sons tag along we were so impressed that I ordered another one for my cycle , purely for ease of use to leave them attached to our bikes and just use the quick release to pop off the trailer bike to swap and change. I do the school run & my husband does the longer weekend rides. It's perfect!!

what are the specs of the bolt on the swinging part?
26 May 2020
I have managed to lose the bolt that connects the tag 100 to the seat mount (in a very a safe place).
What are the specs - length and diameter - so that I can replace it?
Hi, we have no stock and there are is no replacement stock due in soon so I can not measure the bolts for you. Thanks

Can I use this with a adventure a1
24 Apr 2020
Hi, this hitch is not suitable for the Adventure A1 trailer. This is seat post fitting, you need axle or chain stay fitting. Thanks 27/04/2020

Replacement 27.2 to 31.8 shim to use with this hitch
29 May 2019
Hi team, I already own this hitch however I have misplaced some of the included shims. I require a replacement shim to use this with with a 27.2 seatpost. Please can you advise me (link to) of the most suitable and economical shim for this purpose. Many thanks.
We would suggest the Cane Creek as it is Aluminium - sjs#20718S318

Can I use this with a trek tag along?
26 Oct 2018
Measurements seem to work for the Trek.
If the measurements line up, that is the best information you would be able to access, we do not have a simple list of what works and does not.

Thanks - 29/10/18
Can 8 use this with Barracuda Trail Buddy 6

We have no experience of this product so would be unable to confirm if this will work without test fitting it.

Can I use with adventure ditto one tag along bike ? Tnks

Hi there,

As long as the fittings are the same, this should work. We have not fitted or tested it to be more definitive than that.

Do you have the top-hat nylon washers for this please?
01 Jan 2018
they act as spacers on the attachment block.
Hi there,

Please find them using - SJS Cycles part number : 20308

What Seatpost Diameters Will This Fit?
28 Apr 2015
It looks quite small diameter. What is the largest size it can fit, please?

The hitch can fit seatposts of up to 31.8mm in diameter. It can cater for a number of smaller sizes with the Shims supplied.

Will This Fit Avenir Tag Along?
13 Mar 2014
We have an avenir tag 100. We have lost the shims which came with the hitch. Is as looking to buying a whole new hitch. Do you know if this one would fit the avenir tag 100? Or do you supply one that does.

If its just the shims you're after we do offer a wide range of seatpost shims. As for this hitch as we have never tried to fit it to an Avenir trailer I can't say for sure whether or not it will work.
