My Truss fork does not use a normal ‘press on’ crown race but the alterations required are not complicated. Here I explain what will work and how to set things up.
Headsets that are compatible with the Truss fork are (left to right)
1. Cane Creek 10
2. Cane Creek 20
3. Cane Creek 30
4. Cane Creek ‘Jones Assembly’ 100 (silver)
5. Chris King Headset.
All shown with spacers (on top bearing assembly – see notes).
Above, the options and parts for headsets to be used with the Truss fork. The 10, 40 and 110 Cane Creek headsets just need the compression ring (A) under the crown race and a few headset spacers to work with the Truss. The Cane Creek 100 Jones assembly has a special lower bearing cover (B) designed to be used with the Truss and does not need the extra compression ring. To use a Chris King NoThreadSet headsets (the new type with a GripLock bearing cap only) with the Truss fork, add (C) another bearing cap (GripLock type) under the lower bearings in place of the press-on crown race.
Cane Creek 100 ‘Jones Assembly’: The lower bearing cover of this headset is especially made to be used with the Truss forks. It is currently only available in silver.
Cane Creek 10, 40 and 100: Use the plastic compression ring under the crown race. Complete headsets are available with the compression ring and spacers. The compression ring is also available on it’s own.
Chris King: The new type King headset, with the internal compression ring not the rubber O-ring type, will work. Replace the lower crown race with another top bearing cover.
Two upper headset assemblies: It is also possible to use two upper headset bearing assemblies of most headsets with the Truss. The lower assemblies will be upside down and may fill with water and dirt a little sooner than a standard lower.
Assembly information – to make it easier to slide the steerer tube through the fork, thread the fork bolts in from the wrong side with a coin between the clamp slot. This will allow you to spread the clamps a little. Don’t open them more than necessary. Fill the gaps between the fork clamps and headset with spacers. It is good if the last spacer has a tight fit.
Tighten the lower fork bolts evenly to 55-60 inch pounds. Then adjust the headset like normal and then tighten the stem bolts and upper fork clamp last.
You can also put the spacers above or below the headset to affect the frame geometry a little. Put all the spacers on top for a lower bb and steeper angles (quicker feeling) or all below for a higher bb and slacker angles (more laid back). It is not much of a change but it is a little – just mm’s and fractions of a degree.
Scott has been working on the new Spaceframe and Diamond frame bags. They should be ready in about a week.
Dirt Rag sent me through a copy of the review they recently ran (in issue #160) of my bike. And in the UK Shred have a few things to say about a Jones too. Both well worth a read, and thanks to both publications for letting me reproduce the tests here (the files are quite large, and too big for most screens so be patient, and do scroll).
This photo (featured on the home page of my web site) of Scott Felter out on his new bike was taken by Vik Banerjee of The Lazy Randonneur blog .
Scott makes very nice custom bike bags under the name Porcelain Rocket in Victoria, British Colombia.
I have new Spaceframe and Truss fork bags from Scott and I’m testing them out now. They will fit the titanium or steel Spaceframe and Truss fork. We’ll have these bags in stock and more info later in the year.
I’ve been busy with a fair few bikes for customers and I’ll get some words and photos up as soon as I can. And some other developments too. For now here’s news from Europe where Biff has got a green frameset over to a man in Finland. He’s built it up and taken it out for a few rides now. Pictured with normal and fat wheel options. He likes it so far…

“After rides yesterday and today I have to say that it’s worth every cent. It’s super fun and much more capable than even I thought it would be – a few hours ride ride today with some friends having fat bikes or full suspension ones; they pushed, I rode : )
“Cockpit geometry is now sorted too – I ended up fitting a 70mm stem (I tested a bit longer and a bit shorter too). Got a fat wheel yesterday and tested two tires and preferred Larry, Nate is overkill. The bike is an amazing climber… and super fun everywhere else.”
Great riding and trails.
Eric has the Truss fork and is 6’1.
Dan has the unicrown fork and around 5’11″.
It looks like a great time.
This is the titanium bike I’m currently riding. It’s one of the framesets I’ve had made for me. I’m trying out the new XTR Trail hydraulic brakes. The front wheel is a Jones 135-F hub paired with the 72mm front rim and Surly’s Big Fat Larry tire. The rear wheel has a 48mm wide double wall rim with holes that I have as a sample for testing. The bike is set up with 18 gears for now.
And, in other news, two recent customers have been in touch to tell me how they are finding their Jones bikes. They seem quite pleased…
Mary now has her bike (a steel Spaceframe and truss fork) home with her in LA… “It is a truly amazing bicycle and I really appreciate all the ideas and engineering that went into the frame.”
John bought a Ti spaceframe and fork. He is now riding it over in Scotland… “I just want to say you’ve created something quite spectacular with the spaceframe, truss fork and loopbars. Sublime in fact. My expectations were sky high (and wildly inaccurate) but the bike that you boxed up and set to me a few months back has completely blown my mind.”
My trip to Eurobike…
- waiting to unload
- Bike still in travel case
- unpack the bike
- shopping bike
- Farmers market
- supermarkt
- fahrradweg
- pizza!
- waiting for the ferry
- Friedrichshafen
- ferry ride back
I hope to go again next year.
