Lammie hydraulic (did I spelled that right?) disc brakes..

[cezeta]

with the anti dive.....when braking hard over bumps do you lose the suspension at all.....does it go hard?

[sean brady scooters]

that depends upon shockers and springs............

Some racers use the anti-dive ... some dont. The anti dive link has to be fitted right to work. Basically all it does is prevent the caliper from winding up and compressing the suspension. Prange type fork has it built into the design.I think a single disc is enough for road or track imo. There are a few double disc bikes out there tho. The Scoot RS one is allowed in racing in the standards class now and loads use it. Possible pad change, but it works well.

No, that's why the calliper carrier and tie bar need to pivot. The position of the tie bar on the fork leg will affect some of the compresion and feel. My PM hub was set up with the tie bar at a 90 deg angle, but then I fitted MB links which alter the height, this has increased the angle but it feels okay. It'll be interesting to try the clamp on tie rod bracket with the RS one to feel the difference in positions.

how come the mb links change the possition? do they offer more travel?

[mark]

there is always the DACTEK tubless anti dive hub , single disc or double

The ride height is different http://lambrettaspares.com/spareparts/f ... 650pr.html

Can the front Dactek be fitted without a Dactek rear?

mike im interested in the fact that those links are differant do you mean the angle of the curve is less like the s2 fork links
the s2 link is the one at the back of the pic

I'm not sure how, but this is what is said on the MB website...
They are based on a perfect set of Italian GP links but we have altered them slightly to improve the ride height and stop the front dampers fouling on some hydraulic conversions.

Hopefully this link now works MB links

Difficult to say as I've not got the anti-dive for the ScootRS one yet, but the PM type feels great and is not as sharp as the RS one, however this may feel different once the anti-dive is fitted. Also, I think worth mentioning is that the PM is a pig to remove wheels, I dread a front flat by the roadside. Nobody seems to mention that the PM one also require the tyre valve pointing the opposite way. If using tubes, this means reversing the tube, pulling it over, and it requires rubber washers placing under the valve to drop the valve further into the rim so that it clears the calliper, not ideal at all. The tubeless hub version is better but again the valve is turned until it touches the rim. The hubs don't cater for split and tubeless. Again not used RS anti-dive yet so don't know about wheel removal, they are universal for split and tubeless though. So for simplicity, ScootRS.

Double disc is overkill but anti-dive isn't just for racers, it really does make a difference as you don't need stiff springs, so you can have it nice and soft for the bumps, without diving when braking. We all know how awful sudden braking feels with standard front suspension, anti dive cures this.

All this is IMO but I hope it helps

Thank you mate, this is more than help. I was seriously thinking about to go on the PM single anti-dive route, but after your review I'm not so sure about it anymore. The fact you can't fit a split type wheel on the tubeless hub and viceversa is a great fault for me. I'm up for tubeless rims (at least...the good ones that work!) as I think they are an improvement on the safety side, but often could happen that for one reason or another (ex. you suffer a blow out by the way) you have to come back to the good old split rims: if with the PM disc this isn't possible....well I'm a little bit disappointed!
