I'll happily vouch for all of that. These bikes are rare, are beautifully made and work superbly. They use the natural flex in titanium to create a 5" travel bike without the need for pivots.
At the time these were one of the most expensive frames available at north of $3600 or £3000 when imported into the UK. They were very rare when new back in 1997 and only about 270 were made, far fewer ever making it over here.
The rear brake is a standard change that most owners make on these, extending the everyday usability of these for another decade for the owners. These are not only retro bikes but superb regular riders and no garage queens.
Steve Potts is
the only guy worth getting to do the work. His skills beat any UK Ti welder hands down and works in conjunction with John Castellano, the designer of these bikes, to make sure everything is done properly. John even goes as far as to X-ray and scan the frames to ensure there are no weaknesses in the frames before and after the mod. His work isn't cheap but is amazing. John and Steve will even build you a brand new one of these if you have a spare $6500.
The problem is they are so rare that they often the subject of fake auctions and adverts just like merlin newsboys so they often get treated with caution.
As for the seller; he's a regular on here, has a build thread on this bike, has previously listed this bike for sale on here. One to trust - hell yeah!
Oh, and I have one too:
