Absolutely stunning bud... Good look with the canti's, took me a while to fit some but worth it.. I think you fit them at about 45 degree angle then with a 12mm spanner hold the nut and tweak the allen key to the right spring tension.
At first i thought the mod looked a bit rough but given its location and the re-inforcement needed it turned out to be a good job and clearly was the extra needed for a long life forward.
