cruisin my 80s bmx bikes
The blue klunker got a shimano deer head front derailleur to replace the suntour gt150.the 150 wasn't designed to shift a 3 gear front but it did for many miles till I changed the front high gear from a 43t to a 50t.combined with the suntour alpine gear rear derailleur and 34t low gear,it climbs like a goat and has the top end to smoke the road bike group I run into occasionally.non of this stuff was made to work together.the redline flight cranks and mongoose proclass power disc are bmx parts.i drilled the disc to mount the 28t low gear and spaced the gears accordingly. #klunkersarebuiltnotbought
