Nothing special. New Ryno rims, old Ryan Leech 853 frame and fork. I'm an old man with an old bike but havin' a blast. Unsecure image, only https images allowed: http://i24.photobucket.com/albums/c27/rickmarchand/Trialsbike_zpsb038fd6f.jpg
A friend and I just spent the day parts-swapping an Onza Zoot to a Redline MX24 because they feel really similar to ride except the Redline has a shorter TT. Makes it a lot easier to do rotations. Will hopefully have pics in the next few days.
Spare the flaming for a trials novice but do all mods have a 19" rear wheel??
the vast majority of rim brake frames have the brake mounts at the space a 19" wheel would be at, with disc brakes you could theoretically fit a 20" but there's really no reason not to run it like a reasonable mod with the wider rear tire
