Just found this thread, Awesome stuff Here's my Supreme VIP Park with a SB One Boner, Blackspire Snaggle tooth ring & Gusset cog 30/12. next,possibly is a Reverse short block rear hub. I'd been thinking of SS DH for way too long an gave up 4X so, went SS on my DMR Bolt. I REALLY like the different riding style of finding speed an flow from the line an not braking in stead of mashing the pedals an gears. Only had the car park test ATM cos grown up shit but, CANNOT wait to get this to a hill
Bro, I have exactly the same issue. I've got a Session 8 with an X7 derailleur and my chain keeps twitching. I haven't been able to solve the issue yet but i did confirm that the aligment is good and the chain actually gets on top of the sprocket tip. Like if it would be to short. I would like the derailleur to be closer to the sprocket but it's not possible and I've ordered a Rohloff tensioner to see if it helps. Keep me posted if you find a solution.
sounds like it's trying to ghost shift. Try extended limit screws on both the upper and lower
Nope, won't work. The only thing I can do is to adjust it sideways with the short pice of wire I have that usually goes up to the shifter or bring it closer or further away from the sprocket. I don't think its close enough now but even if I replace the adjuster screw with a longer one it will start to press on the wrong surface at the derailleur. Whenever I start to pedal, the chain climbs up on the sprocket.
Old mechs can flap about a bit no matter how limited off they are. A quick fix I found was to stick a couple of zip ties around the parallelogram to stop it from trying to shift. Getting a proper tensioner is a good idea though

That's seriously a rad set up man. Thumbs down to 'grown up shit' lol.
Just converted my Furious to zingle speed. After seeing it work out for a couple of you guys I gave it a go. A cutoff wheel and a punch made pretty easy work of the stock Zee derailleur. For what it is, I'd definitely recommend the conversion. Brand new Zee derailleurs with a clutch are cheaper than most of the spring driven tensioners on the market.
What's that chain device with the lower jockey wheel? Is it tensioned? Could you ditch the tensioner off the rear? Something I've been looking for for ages...
It's only an old broken chain guide repaired with a Shimano pulley, tensioner is the standard sb1 DH in the rear. sb1 is making a new tensioner for the pinion gearbox which will be mounted near the BB. Maybe this will be convertible to icg mounts. Have a look at their insta/fb.
