IMPORTANT: This bike has an un-released version of the Jackpot frame. I originally had a lot of problems with the press-fit bottom bracket on the official frame and Onza replaced with a new (never released) threaded BB version which is MUCH more reliable. In my opinion the press-fit BB is the only thing wrong with the Jackpot and this one doesn't have this problem!


Stored indoors and pretty much as good as new. (I think better actually!) It has recently had a service at a professional bike shop including a new cassette and chain.


I'm also happy to include:

* Kenda Honey Badger 27.5 x 2.35 original tyres - They make for great summer tyres/spares

* Brand new bottle cage

* Front and rear mudguards - Work excellently (Front mudguard pictured)


It hasn't been ridden much and is in very good condition. There a little surface damage from the chain on the chainstay as you would exepct on any mountain bike.


I'm very sad to see it go. Selling because I don't have the space and I don't get to ride it much. The frame was replaced in 2020 and hasn't been ridden much since. This bike is really fun to ride and very reliable. It will last you a lifetime.
