Additional Info

Bought it used from TPC and swapped the fork, shock, brakes, seat, seatpost, and cranks. Your first thought is most likely "DAMN that's a heavy trail bike" and you are right, but I could use the workout.. and it rides well so eh, Im good with it. That said, I could easily drop about 6-7 pounds off this bad by with wheel/tire swap (it has cush core, DH casing tires, and double wall alu wheels) and putting on the original shock and fork. This is just more fun.. and looks good too.

It's a lot of fun and there are a lot of things I love about the gearbox. For simplicity sake I think my next one will be a regular drivetrain though.

Right on, curious what drives you to a derailleur? I've only been gearboxing for a bit now, but so far I'm convinced my next enduro bike must have one.

As far as use and performance goes I really love and prefer my pinion set up. Shifts are always crisp and concise, and I know exactly what gear Im in with the numbers on the grip shift. My only gripe is that its hard to get support or spare parts anywhere for a gearbox locally. I had the belt on this one break 1 day prior to a trip and couldnt source a spare in time so took a hardtail instead. To be safe on longer adventures you would have to carry an entire belt as a spare, rather than just a link, which would have gotten me back in action right away. There are lot of ways you can compromise a belt to without even knowing so you have to be a little careful with them. Mine snapped with no real warnings and probably had around 200 miles on it only.

Thanks! It definitely worries me not having a spare belt on hand, and I plan on ordering one before I head out racing, or even a bigger trip. 
I've been a bit worried about hitting the belt or gearbox on rocks, as it'd be a much bigger ordeal than a derailleur if it is damaged. That said, I believe the spare parts availability is currently the biggest hurdle aside from being able to try it (that was non-negotiable for me before purchase. Clearly it impressed me ). I'm hoping by putting my money where my "derailleurs are stupid" mouth is, some shops will eventually get on board. Until then, I better look up the belt length I should order!

Yeah honestly I would just say to buy a few extra shifters (I’ve already broken one) as they stick out and are a weak plastic. Unless you get smart shift, which is what I would do now. If you have that, an extra belt or two, an oil change kit, and the pinion socket tool on hand you should be set for most issues. What gearbox frame are you gonna build up??

I got the Zerode G3 at the end of the summer. Very stoked on it! Did get the smart.shift indeed, I don't think I'd have been happy with grip shift but I haven't tried it.

If your question was about what enduro I'd be thinking I'm not too sure. Yours looks like a decent option. I also like the Taniwha a lot, but I'd need a bit shorter seat tube. Haven't really looked at options for pedal bikes yet since I just bought a dh. But I also just found a crack on my enduro bike so if I can't get a warranty, I may have to look into it.. 

Do you know if the P and C lines use the same mounting pattern? I'm starting to understand they are interchangeable, as well as the new Effigear fitting the same mounts? I feel like I'm just learning about bikes again haha.

Daaang, now thats a proper DH bike. High pivot and gearbox, what more could you ask for. 

What enduro bike do you have that cracked?? unfortunately they dont make my frame anymore from what I've heard. The Saturn kind of took its place. I got this bike for dirt cheap, otherwise I would have actually gone for a Nicolai Nucleon with the supre drive. That or the Kavenz gearbox bike.

I believe the C and P line share the same mounts, no idea about effigear though. That is one thing I like about this bike though. Even though its heavy the P line has a stronger casing and a better cover over the planetary gears to keep crud out.

Thanks man! Its definitely the most color coordinated build I've done so far. Just added new images with HEL brake adaptors that are also red and shaped to only fit their calipers. Its ridiculous but damn does it look good ha. Rides just as good as it looks too.
