I have a 20" Large Scott Spark 50 2009 that is in great condition with only around 100 hours riding under its belt (i live in London so isnt out every weekend), all original (apart from pedals which are red V8's) Spec is as follows
Some cable rubbing marks and a graze to the rear triangle, but overall great conditon. Voted one of What Mountain Bikes best all trial bikes, and it has eaten up Dalbeattie, Afan etc without any problems at all and flys through Bedgebury! Just had a service at Skyline Cyles at Afan, (headset, hubs, gears, brakes and had a new bottom bracket about 40 miles ago)
Im looking to up the travel to a 140/150mm bike and you might be wanting to switch to a super fast 120mm, prefable a Scott Genius (not an MC) as ive found Scott bikes have amazing realiability and the spark has been bomb proof, but also open to other offers such as an Ibis Mojo HD or Yeti 575 (obvious p/x)etc..
If you interested please email me with what you've got at email@example.com and ill send over some photos etc!
