Maybe this has been posted before .... if so apologies.
I've had the tips installed for about 1700 miles. One of the two decided to make a break for the ditch whilst I was out for a 75 mile ride. Came back home to disappointment. Went to Dean's site and it was sort of shut down. Left him a voice mail and he followed up by text. Had none in stock and worse ... he is recovering from illness. I gather not too serious, but it partially shuttered the business. Talked to him on the phone and apparently I'm not the only one kicking the bushes looking for a lost tip. I suspect that the clamp is insufficient to retain the tips. No excuse ... I should have checked the clamps "regularly", but I had more fun things to do. Anyway - if you haven't cinched your tips clamps in a while ....... I am going to to through drill and slip a bolt and nut under the clamp. Safety wire the screw as well. Cheers - Jim
PS - You'd be well advised to contact Dean right now as he's ordering material to knock up some tips.
