Dan asked what the fitting was on Robin's TTR featured in the MCN adventure supplement here
I asked Robin and got a really helpful reply as follows with lots of photos:
"For that trip (Algeria) it was a D lock and tool box.
Photos attached plus some other versions. -Done many.
It was 110mm drain pipe with some really good twist and go, lockable KRS end caps.
Don’t use the screw on threaded type in the desert. The sand quickly clogs up the thread.
I like the ‘keyed – alike’ abus padlocks. Bought a lifetime supply. For the tool box and other stuff . (use for a disk lock/ cable lock etc. One keys fits all.
The D lock was two welded together. Mounted in drilled out Renthal handle bars! Dual or triple purpose in design e.g. lock. Opposite side stand makes a centre stand and for a foot rest on long stretches.
There are a few photos of other set ups.
I got some ali tool boxes fabricated, locked and sealed lids. And elasticated with inner tube strap bungy so it would swing in in a crash.
The tube opposite the exhaust is a good set up.
Plus the left hand side sub frame bracing.
Also you can see the seat support I added under the fender pack. Am going to have another go at making a longer seat.
BUT!
I have pared down my set up so many times. Have actually moved back towards less clobber. Just a few pouches now really.
I did a tool kit review a few years back and can do most things with not much now. So need a less big tool box.
Spare levers are cable tied to the frame as are spare mini pump and motion pro spanner/ levers, cables and other bits.
As I am running tubeless now I hardly need the tyre levers. Even for the rare puncture."
