Shudder judder at speed when braking
I'm back on a bike after a a long period off with a busted elbow, got myself a spanking new TCR Composite with ultegra brakes/groupset (all the gear and truly no idea)
I tackled my first proper climb on Monday for a year and I think reasonably cautiously wanted to use my brakes on the way down... however at speed upon approach to the first corner, put on the front brake and experienced a judder which came up the fork like I've not known before, while it was happening (through the terror) I thought it could be a loose headset, front brake and it even crossed my mind that I may not have tightened the front QR skewer !
While my mate fearlessly swept around the corners and crept up to 47/48mph I 'juddered' down in sheer terror at 44mph for the (0.5mile @ 12% avg) decent.
I've read quite a lot of this shudder and most people say it's the brakes, my question is what should i do about it? it's a new bike is it a warranty issue? setup issue? could it be that my headseat which don't appear to be loose..
Or is it a technique thing?
