When I contacted them about this, this was the reply I got ...
Do not worry, this misalignment is unfortunately inevitable if you combine 2 different handmade 3D welding parts.Please fix the upper bolt first (not tight but at least 4-5 threads)and pull the lowrider forward to fix the lower bolts.The upper tube will create its unique wave to fit perfectly to the very Spirit frame.Tighten all bolts afterwards.
I wasn't very impressed by this but I thought okay I'll try again and give them the benefit of the doubt. Now I'm no Brunel but I have been servicing & putting bikes together for over 30 years. But there was no way this rack was going on unless brute force of not one but 2 people was involved with the risk of threads being stripped. And though I've honestly tried to get it to fit there was no way I was going the inflict further scratches on my paintwork.
This got me really, really peeved is it now too much to ask of a recumbent maker to make IN HOUSE a rack that fits properly. Seriously!!
I'm not going to mention any names but we're talking about a well known maker of quality recumbents. The only way I'll be able to get this to fit will be to make modifications with my Dremmel which I'm happy to do but I'm not paying them full price for something that doesn't fit properly and I've had to bodge.
What would you do?
