? the way the bar is behind the seat tube leads me to belive it may be later than a 85 much later it does look nice
dude dont take this the wrong way but i even posted this in a post earlier i saw  a dyno at toys  r  us and thats what the frame looked like with a real skinny  plate behind the seat tube i may be wrong but i do remember that about the toys  r  us model   i will say this if you did that bike up your self it is a nice job though

i never heard of a 85 dyno.. i thought the first year they made a bike was 1987...   US made serial #'s have the date the bike was made in them... i have those same decals on my 87 detour, i didnt know what they were supposed to go on because i never heard of a D-30.... what is the serial # on this bike??? i never seen the single plate behind the seat tube either but the frame does look like an old school frame NOT a much later 90's frame...

BTW, I restored this bike back to Spec right down to 1985 dated Dia-Compe brake cables that I paid Biaggio an arm and a leg for.

hey bro i saw on a BMX site all the history on bike companys.... the dyno section said they came out in 87 and it was their first complete bike... before that it was parts and stuff..... ok i went to look at the site and sure enough they have changed the history on the dyno page.... it does show your 85 D-30...   here is a link for everyone to check it out  http://www.23mag.com/com/dyno/dyno.htm

I didn't mean to come off sounding mad.  Sorry about that.
The 85 and early 86 D-30s came with the single plate.  That proved to be a week spot in the frame and many of them cracked at that spot.  Later in 86 a second lower plate was added for strength.  In 87 the ProCompe came with the two plates boxed in which strengthened the spot even more.  Still sounds funny to hear Dyno and Toys-r-us in the same sentence.  Pacific is running all the former quality brand names into the dirt, just to turn a profit.  Scumbags.

It should have a stamp.  The GT factories had some quality control issues though with respect to stamping though.  I wouldn't be surprised if it didn't get a stamp.  I have a Japanese early 86 single plate frame that does have the stamp.  Does the SN on yours start with a G6?

Yep, that's an 85.  Some of those frames had very light stamps that actually got completely filled in with thick coats of paint at the factory.  I didn't think mine even had a serial number until I stripped the original paint.

i just found the same bike

super nice 85' compe!

thats a rare and sick dyno!  nothing but props from me,  I have a couple 80's dyno models but none that old or rare.

Ha Keith... Drama seems to follow me at this site.  I do instigate a bit of it though.... LOL.

MAYNE!!!  The first bmx I picked out was an 85 first series dyno...  I think I had it 3 months before the lock got cut   


NICE BIKE!!!
