Old Zoo Pitbull brought back to life

0 comments

After being off any type of trials riding for 6 or 7 years, getting back in the saddle in order to teach my 5 years old. Surprisingly still feel comfortable on the bike. Was on Observed trials forums years ago, but does not seem to be any activity over there anymore.

  • Purchased this in 2014 with the intention of getting into trials. Broke my collarbone on my roadie and never got very far with trials. I'm back at it again, this time with my 10 year old daughter who rides a mod.
  • heres a thread i see alot on mtb forums, thought id give it a try here just post what you think is the coolest or sexiest trials bike heres one to starts us off i quite like the look of these classic 221s i really want to ride one
  • Recently I got my Marino 26" frames back. (I have two identical frames, one in blue and one in red). The blue one is the fun one, so here it is. I'll update this thread as I make some changes to it. Geo is 1060, +80, 377, with a 73 degree headtube. Reach is 680. The long reach allowed me to go with a 130mm stem right off the bat and felt good. The goal is to have something that is flickable, and fun, that still feels decent on rear wheel moves. The shorter wheelbase and slightly shorter chainstay make this manual nicely. I've got to work up some confidence on rolling bunnyhops, but it should be nice. With the super high BB it still does rear moves and sidehops decently with the bars rolled back into a less visually oppressive angle. I liked the idea of MTB cranks and a hope hub on a pure bike. It took a bit more modification / grinding than I would've liked to get the cranks to work. Having the rim brake slave cylinders made the clearance super difficult and I had to sand the pads down to almost nothing and take about 1mm off the back of the drive side crank. At some point when I have some more funds, I may try a boost crank made for a 83mm bb. Front Magura MT7 and rear Trialtech are a super nice combo. The Magura is working like crap since I moved it over, the disc mount must be at a slightly different angle or something. So far the rear trialtech Carthy rim is pretty nice! I love not seeing cutouts and it feels super stiff. The coust pads on it are a amazing. The rear heatsink tensioner is a bit sloppy looking. Originally Marino said he'd be able to fabricate a crewkerz style mount, but then wasn't able to figure it out in the end. Maybe at some point I'll weld one on myself (bonus of steel). Due to the gear ratio on this, there is just a lot of slack to take up. Maybe using a half link would help. I can put a hanger on it and just go with an old school two wheel tensioner too. At some point I will go rear tubeless on this bike. But right not it is fairly cold and my tires just feel like crap no matter what so I'm not stressing it. Tire clearance is a bit of an issue, I had to trim a couple center knobs a mm or two to get it to stop rubbing. The Inspired Arcade bars look incredible, but I am going to try my crewkerz bars on my next ride. Betwen the 73 degree head angle and the streety bars, the front end felt so different it was hard to get used to.
