Project321 Hubs (industry9 internals in rear hub)Posted 4 years ago
Thumbprint Tuning Hefty fork with effectively 90mm travel (axle to crown is exactly the same as Krampus rigid fork, and it has new RockShox air cartridge with a lockout)
Rabbit hole rims
120tpi Knards 3″x29″ with 20mm? Travel 😀
32t narrow wide from raceface
Everything else from previous bike
I did. They are a project 321 set with 1 1/8 steerer. It allows your to spread the whole fork out to the left to compensate for the dishing of the wheel to give enough clearance to use the Rabbit Hole rimes and Knard without a worry. TBH the dishing is a lot, although the tension in the spokes is balance on either side of the hub and if there is a need to rebuild the wheel, I would bring it back a little, as it currently has about an inch of clearance from the stanchion with the tyre fully inflated. it is all aligned nicely.Posted 4 years ago
The rim is 50mm wide. The inflated knard is 770 wide on the rim. I would get a dirty great big hole in the stanchion and a ruined tyre. So, the front week is offset(using one side spoke wholes which are 5mm from center. The crowns on originals have a tooth that aligned the spindle of the fork in a groove. Special ones don’t have this so you can rotate the stanchion as you spread the fork out wider to compensate for the dishing of the wheel.Posted 4 years ago
It rides brilliantly! It picks up speed alarmingly and I will have to get used to the way the bike wants to bulldoze the trail whilst actually being really nimble too. I have to admit to being a little paranoid about being wedged between trees at the moment, but I’ll get passed that….or not 😯Posted 4 years agosinglespeedstuSubscriber

If i’m reading that right you’re rotating the clamps outward to get more sidewards offset?
Does that not then alter the forwards offset of the fork and bring everything further back.
I though the 321 clamp was wider to get the tyre clearance?
Looks good BTW.Posted 4 years agobikebouyMember
Looks like a great build and a proper fun bike to ride that.
I too wasn’t sure what function the Lefty was performing, but if it works in your environment then it’s a good fit and as you say, will cause children to point and (laugh) snigger or pose the question “where’s the other leg” (it was a recurring question I had when I had my lefty)
Doesn’t look dirty enough, suggest you ride it harder 😆Posted 4 years ago
The decal or the fork ir_bandito? Can get more made if you want a decal. in regards to the Hefty fork, contact Tony.
Bikebouy I live in the south….it’s not very muddy down here, but a little flat. Tbh I was 5 mins into the ride and had stopped to tighten up the bolts etc as it was the first ride….big smiles, as it rides brilliantly. It climbs in a way I have only experienced back in the day when 1″ threaded headsets were all the rage and Orange still made all of their bikes in the UK, suspension at both ends was a pipe dream, and we all had an embarrassing relationship to dayglo Lycra.
Singlespeedstu the overall wheelbase is only a tiny bit shorter than the rigid Surly fork now, where as if you used the standard clamps I am fairly sure that the effective wheelbase would be longer than Surly intended. Also, the offset in the front wheel is really playing it safe. I have massive clearance as you can see in the pics, so if you wanted to do this kind of build I have been given some spoke lengths by the wheel builder, Bungle in Wareham, that would be less extreme, so the clamps wouldn’t need to be so far to the left. With the lock out activated, it rides really well, but with the Lefty working it soaks up everything and grips even more. it accelerates with an unnerving sense of being strapped to the outside of a 50 tonne truck falling off a very tall cliff. It’s awesomePosted 4 years ago
If you already have a lefty max from that period then it will be cheaper, but only (there is a Link if you look in my previous post) to Tony, who built the fork for me. The project321 Clamps were $200. I would recommend both companies as they both were great to deal with, and if you talk to Tony, ask him about his gravity bike….it’s bloomin fantastic!Posted 4 years ago
It’s fat enough for now. I don’t live in a snow bound part of the UK, and beaches are a long way from me. They look brilliant. Dave at Charlie’s cave was building up a Moonlader as I was fettling. it was khaki green and looked like a hoot. I have a need to have a go, and Charlie wants a play on my Hefty, so I’ll see. Coffers empty for now 😀Posted 4 years ago
