I've just had...
... the latest version (Evo III) of the 321 Inition! de-link done on my bike two weeks ago.
17 bits come off the bike, 14 hoses and 3 other lumpy componants (including the secondary master cylinder).
If you have the latest version of the de-link only 4 hoses plus two ported CNC machined anodised aluminium bridging blocks go back on. I weighed all the bits that came off and there is a weight saving of around 6.5 lbs.
If you have the Evo II version there is six hoses (no blocks) and it's about ?40 cheaper. Seb uses Goodridge braided hoses so there is no compromise on quality.
I 'spose de-linking is not everybody's cup of tea, as are the brakes when still linked.
With the de-link done I personally have found the brakes are more responsive and you have more control over whats going on at each wheel. For the first time you are utilising all three pistons on any given caliper with just the one operation, so the individual efficiency of each brake is improved by a quantum amount.
You're not having to supplement front braking power with use of the rear pedal, which you currently have to do to operate the third piston on the front calipers (and vice-versa)... Front braking power now is hugely improved, in relation to use of the front brake lever, if you know what I'm trying to explain - about 33% by my reckoning.
Goodridge hoses are always going to sharpen response as the hose swelling you get with the stock hoses is eliminated, but I have found the de-link absolutely superb. I wish now that I'd had it done ages ago...
I'll soon be posting some pics of my mods (couple days) and I'll include a close up of the new mounting arrangement for the front calipers - very neat and tidy it is too.
