Newbie [old] guy here. I saw a trials demo at Whistler B.C. last week and was amazed. Knowing of both moto and bicycle trials, I even had a TL250 for a short while when I was young[er], yet I never pursued it on a bicycle [again, yet]. So I started doing reseach on hardware this week. I have a MTB (old Klein Rascal) and have given thought to converting it for a "stocker". I've considered starting with a BMX, with a few mods, (cheap and plentiful and my 6YO son would have another bike to play on). I've considered getting a used mod bike. An odd question just occured to me however. Why aren't "cruiser" size bikes used for trails? Obviously there's the mod camp (20") and the stock camp (26") but wouldn't a 24" sized frame and tire be [almost] the best of both camps? Great forum!
