Are you running X-Fusion instead of Bos now... any reason?
LOL well spotted! There is a long story about this <big sigh>
Basically when I changed my frame (I got an updated and fully tailored AM) I also changed head sets, from straight 1 1/8th to ZS tapered. That necessitated a new headset.
The base plate on the BOS forks on the old frame/headset combo was always an easy fit. It was a CK steel set, so no split race, but even so, I could put it on and take it off by hand. It was never a problem on the old frame but when I moved to the new frame and changed to a Reset racing headset, turns out that the base plate on that unit moved on the BOS steerer. Even when it was all clamped together, there was play in the front.
Measuring the steerer tube on the BOS fork it turns out that it's fractionally under sized. Tolerances between the CK and Reset racing units just meant I got away with it with the CK unit, but not the Reset unit.
I identified all this back in October but of course, there was no distributor in the UK for BOS. So even though it should have been dealt with as a warranty issue, it wasn't. I knew I would be able to sort it some how, but I also knew that it would probably take forever to resolve. With my smashed arm healing, I decided to just buy another fork as a stop gap so that I could at least get riding again and then use the extra fork as a good excuse to build up another bike.
I ended up buying the X-Fusion fork as it was the least expensive/best performing option.
Surf Sales have been fantastic in trying to help me though. It's not resolved as yet as they are trying to convince BOS to cover the cost of putting the fork right. BOS acknowledge that my fork was part of a batch that all had the same problem, but they were initially saying that because it was out of warranty, they wouldn't fix it.
Which is a bit rich because there was no way I could access the warranty when the problem was identified.
Surf have said that they will at least let me buy a new steerer assembly from them at cost and fit and service the fork for free, which is really good of them but will still cost me £150. But they are trying to persuade BOS that because of the lack of UK distributor last year, that they should cover it.
Like I said, <big sigh>
The Vengeance is perfectly good; not as good as the BOS and it's definitely noticeable but I suspect not any slower as a result. It is however, 250g heavier.
