Tool tube mounting

Neat.

I would like to suggest you turn the one clamp around in order to form a 'triangle' between the three bolts. You might find that after some gravel roads the whole unit will 'pivot' around the bike frame due to the offset weight.

The 'best' would be if you attach the unit with 4 bolts to balance it out. Going to be tight at the back though.

There are actually a lot of sideways vibrations while riding. This will strain the small diameter where the plastic get clamped between the washers.  You can also buy oversize flat washers at the hardware store to increase the 'footprint' on the plastic.

Looking at the pics again, maybe two 'saddle clamps' could be a better option as there will be NO oscilation of the tube. Easy spacers could be used to clear the other parts of the frame.  (Longer bolts to sandwich the tool tube required?)

Hose Clamp

Also from Hyflo

Thanks Adie

I was also concerned at having the 2 bolts aligned, but if I offset them then I could not use the center hole on the tube and the entire tube would be skew.

Using a hose clamp would necessitate me removing the small panel on the side (cosmetic)

I am going to have another look at it this weekend to see if I can "improve" it.

Perhaps using rubber washer(s) will minimise the vibration stress at the mounting holes.

I use a couple of cable ties - not very aesthetically pleasing, but takes care of the vibration - and the tube is still firmly attached.

I rode with one of Andy's radio antennas attached on the tube's mounting plate on the Sutherland trip. The mounting plate sheared in half on day two due to the additional vibration caused by the antenna.

Thanks for information........

Anyone wanting idea's for mounting the tubes......... email me at peter(at)tourbikebits(dot)com

I have a whole collection of pics of tube mounting options etc. and it will be easier to email to you than post here....

Have ever fitted a tool tube to a Funduro? You can mail me on d.schilder@telkomsa.net regards Viper1wp

Last weekend following all the suggestions I had a rethink and remounted the tube. I ended up taking off the cosmetic "bikini" panels on either side and used the mounts to attach the tube. It is now very secure and cannot interfere with the rear wheel travel. I also overengineered by placing rubber washers for vibration reduction. Must I post pics ?

you must!

Here are some pics of new mounting....

Removed "bikini" panel and used its bracket on left hand side

Mounted at slight angle to make sure it is not in the way of rear wheel travel.

Original bolts and holes used. Only need to remove the sleeve from the bracket as it needs the play to fit.

Still use a "P" clamp on the one side. Cable ties as backup !
