    Mal,

    In looking again, I just noticed that you have mounted it to the top of the bash plate on the right hand side. Is that a frame rail behind the bash plate or something the plate protects. I’m guessing it’s a frame rail that the bash plate rests up against. If not the pipe guard will get a fair bit of leverage to bend the bash plate. Not sure where else you could mount it though that doesn’t give the pipe guard heaps of leverage on its mounts. The bloody pipes just stick out too far past the frame.

    In saying all that, when I had mine off the other day doing the top end I noticed it has copped most of its hits in two areas. Mostly directly underneath from climbing very slow over things on hills etc and only just getting the front wheel over before coming down and stopping with a bang. I’m probably a bit lazier than I should be too because I know it’s there.

    The other spot is up high on either side. These tend to be higher speed hits as they are generally catching on stumps etc after something else has sent you skewif and off line into it. The bad news about these hits are they have maximum leverage on the guard mounts as they hit the guard the furthest distance from the mounts.

    Worst case I’ve had is, I was in the process of falling off after hitting a rock at about 60km/hr. Bike was off the ground and heading towards getting horizontal (seat level with wheels) when the pipe guard caught the top of a tree stump. Stopped the bike dead. I continued on in my original trajectory. Luckily both the bike and I were unscathed and I could continue the race but that was one occasion when the guard needed some remolding.

    That part of the bash plate protects the water pump Bundy. The problem is the getting the mounts for the frame. I may have to make something to go from the bash plate back to the frame because you could be right with the leverage thing. I’ll look at it closer next week.
