Newbie here, so please excuse my ignorance.  Just learning...

I am looking to build a chiner 29er trail or all mountain bike, theoretically with 140mm travel on the front fork.  Problem is I can't find the right full suspension frame that will accommodate that amount of travel.  Looked at various 036 models, but the specs are 100 or 120mm for front travel.

Any ideas on how to proceed with this?  All suggestions and smirks welcomed!
