I have a mongoose solution frame, forks, stem, post and clamp. The frame No. is K4111627.
When I got it (at the last real backyard jam) I was told it was a prototype team model. It has an odd size (not one and an eighth or one inch) headtube and forks. One of the first ones with a clamp on stem.
It's had a hard life and is cracked but I'm thinking of getting it fixed and putting it together. If anyone can give me any imformation on it I'd be very gratefull.
In case your wondering I will not be selling as this was my favourite bike for years and I still love it now.
