Ofer got in touch with me recently as he had a new build he wanted to share – naturally I was happy to help…
He was inspired after seeing the custom titanium frames that DeSalvo make and decided to combine elements of those with the geometry of his existing Jamis Dragon One singlespeed 29er. Ofer also got XACD to make him a rigid titanium fork to compliment the frame.
He certainly sounds pleased with the results, particularly the fork which adds an element of comfort to the front end. As you might expect with a minimalist build the whole bike also comes in at under 21lbs (9.5kg).
Ofer thought that Porter offered a professional service but the delivery did take quite a bit longer then he was initially promised – three months rather than one!
Ofer went for a pretty stock XACD frame but put his own tweaks to it – the curved top tube being the most obvious. Slightly more hidden is the increased wall thickness on the downtube and chainstays, up from 0.9mm to 1.2mm.
I’m guessing here that he was after greater strength without wanting the ‘oversize’ tubing look. It would probably have been fine to stick with the 0.9mm wall thickness, although I might have suggested increasing the diameter of the downtube to 40 or 42mm which would have added strength and stiffness without much of a weight penalty.
Ofer finished the frame off with some tidy looking horizontal single speed dropouts with inbuilt adjusters. Probably the most eye catching item though is his rather unique head badge which looks like it was made from a real rear sprocket. It came from custom jewelry specialist Jennifer Green, you can find out more over here: www.headbadges.com
I’m more concerned about the titanium fork though – historically performance hasn’t been that reliable, particularly the batch that XACD made for Spicer about six years ago. The main point of failure appeared to be the strength of the tubing used to make the fork legs, hopefully they have increased both the diameter and the wall thickness, particularly for the 29er version. I’ve asked Ofer to keep us posted on how it goes but personally I’d recommend sticking with an off the shelf carbon fork from a familiar brand.
I did ask Ofer if he might think about changing anything about his design should he have another frame made but it sounds like he’s got it pretty right first time:
For a second version I might go for a slightly shorter chain stay but it’s really not a big deal. As I said before – I am still in love with this bike 🙂
Have you had a frame made by XACD? If so I’d love to hear about it and maybe feature it in the Gallery so drop me a line via the contacts page.
