Front uprights and cycle wings

GBS came through with the replacement long bolt for the rear uprights and pinch bolts for the front uprights.

Straight bolts this time - the old one was like a banana and wouldn't go through the long bottom tube on the rear upright:

The cycle wing assembly needed a little cleaning up with emery paper by hand to remove the top surface/shine where it slides into the Sierra uprights. I also cleaned out the uprights themselves with a drum sander. Both went in fine, a little grease (hindsight: any grease might be a bad idea, these have to lock solid with the uprights) & one side with a little persuasion from a rubber mallet.



These parts are handed, with a notch on the offside/right side cycle wing bracket: (this is nearside so no notch):


These are not torqued up yet - I want the wheels/tyres in situe to line everything up before doing so.

Update (Feb 2013) - theres an interesting thread on RhoCar about making doubly sure this bolt doesn't come undone, I'm planning to upgrade this pinch bolt to take a nyloc on the end & a couple of roll pins 'belt and braces' so the dummy shaft cannot pull out of the upright see Here
