This one looks awesome. Very similar to the smallframe kit he's been producing for a while now. A few shops are carrying it, SIP included apparently but I can't find it there. On his facebook page he's not saying a whole lot about it.... these pics are from fb and Duepercento mainly. Also a little video where he tries linking the front and rear brakes hydraulically - with a bit of success apparently.
Looks like I can't post the video, see if this works...

Chatted with him a little last night on fb. I asked if he had done anything about the diving when under brakes.

If you want to improve so you have to put the disc to the rear wheel and do full braking.
Must be controlled by the pump on the right lever
This is referring to the linked two disc setup in the video. I asked if he had some way of balancing front and rear braking force and he said no.

Damn you, you know I've wanted a disc brake set-up on the Rally and now I'm going to have to look in to this and see if it is a simpler option. Sigh.

Well it is. You don't need to change the fork for a start... he assures us they are all bolt-on.

Sounds just too good to be true, but I am up for a plug and play always. Roll on December. Thanks for the info Michael.

Apparently the attached sheet should have been in the box. I think it says I need to pull out the grease nipple and fir a rubber stopper (none in the box) in its place.

Anyone able to point to a good thread (with pictures for this slow learner) showing how to pull a Sprint/Super front hub apart and put it back together? And/or how to do the same with the spring (Pictures ditto...)

I promise to sprinkle this thread with install photo's in return (f I can figure out how to route the brake hose)

Thanks, hope lock down is over quickly for you guys in Melbourne.

I've put one of these on my 125 t.s. It works very well but of course the front does dive under braking so you have to be careful.

When I fitted the kit I also replaced the spring with a stiffer one, the damper with a BGM PRO Sport, I also replaced all the bearings, the spring attachment and other bits of hardware.

Add to that a brake lever/master cylinder combo and the brake hose, then things are getting close to the PK fork conversion price, which is probably what I would do next time for a tuned oldie.

To fit the kit and to do anything to the hub, axel or the caliper, once the kit is fitted, you have to remove the disc from the hub by removing the 5 torx head screws. So you need a good quality torx screwdriver. There are no instructions, so no torque settings, you need to tighten everything as much as you think and I used locktight on everything with a thread. The kit fits straight onto the exisitng forks with no drilling or welding, so you can easily revert back to the original brakes.

I fitted mine during the christmas holiday 2019 and have only had one problem since. The screw holding the caliper bracket came loose inside the hub after a very serious emergency stop. So of course everything has to be removed to get to it.

Finally, you have to learn how to bleed brakes, bear in mind that brake fluid is hygroscopic so it attracts moisture, I learnt the hardway that it isn't a job for a rainy day....

Alan, he hasn't ridden it much. I did have a 10 minute ride and the brakes worked very well. As PeteB notes though, you need a good shock and spring - people are saying that the SIP shock and stock spring are a good combination. Something about a stiff spring not allowing the shock to work to it's full capacity.

I don't have it on mine obviously, but I did just buy the new Crimaz master cylinder - version 2, and it's a lovely thing. Very discreet with a built in reservoir.

Which bike is that one?? It looks weirdly unblemished

Thanks for the update. Might have to lug a set or two back with me when I can enter Australia once more. One for the Rally and one for the Sprint. Seems the easiest solution for adding a Disc set-up. Keep your phone on

Thanks Pete, I like the locktight and torx screwdriver tips. Definitely some points to consider when comparing the Disc options. Cheers

Isn't it? And it fits!! My only grumble (and it's small) is that the outlet for the hydraulic line is from the bottom rather than the side. So less chance to keep it hidden, but still nice.

I'd like to see a linked setup with drum rear. Maybe have a hydraulic cylinder that mounts underneath and pulls on the rear drum cable?

I was looking at playing with a hydraulic clutch and lever.

You could do a rear brake the same way, but you'd have to figure out how to connect the master cylinder to the brake pedal. I have thoughts, basically mount it to the side of the tunnel like the brake light switch, but nothing solid until I get one to look at and can figure out how what you would need to chop off and then add mounting bolts.

How close to being on the road is it. Will you make the not-the Mille, not that I'm sure you'd want to ride a smallframe that far?

We will have moved back down under by this time next year all things being well with the world once more. Kind of wish we had of bitten the bullet and headed to Perth at the first inkling of this

Would have been plenty of time to get 'Alice's' Sprint sorted I suspect.

Crimaz did try that, it was a couple of years ago so I assume he thought there was not much call for it. Uses discs both ends. His method was... kinda crude you might say, but he said it worked well. Just run both calipers off the same master cylinder, no biasing or anything. Or rear only via the pedal. There's a video here -

In the rear drum remain the original jaws operated by the standard pedal.
The right handlebar lever operates both pliers simultaneously

I'm still hoping it will possible. Numbers are looking good atm. Just a matter of having time to run it in and deal with any issues that might come up. "Alice's Sprint". Good one!
