1999 GT Speed Series Team XL

With a retail price of $1,139.99, the 1999 GT Speed Series Team XL bike was one of the most expensive stock BMX bikes available in 1999.


I bought this bike while on vacation in Southern California on April 4, 2012 from its original owner.  I can't say that it was cheap, but who else has a '99 GT Speed Series Team XL bike in essentially new condition?  The bike was originally purchased from GT shortly after they closed their Santa Anna, CA manufacturing facility back in Spring 2000 ([-0046-]).  Prior to owning this bike, it spent 12 years in a So. Cal. body shop collecting dust!


This is BMX Museum's first completely stock and mint 1999 GT Speed Series Team XL bike.  It has very minor brake rub on the rear rim, but other than that, the bike is brand new and in perfect condition.  Not a single bolt has been loosened since the original purchase of the bike, and I intend to keep it that way.  This bike retailed for $1,139.99 USD back in 1999, making it one of the most expensive stock BMX bikes available in 1999 (Source: BikePedia).


It is noted that both the 1999 and 2000 GT Speed Series Team XL bikes are identical.  The serial number is the only way to tell if you have a 1999 or 2000 model-year bike.  However, many advertisements for the 1999 GT Speed Series Team XL bike show that this bike came stock with a regular (non-inverted) GT Piston XL stem, a GT Micro Adjust seat post stat has a slightly different "GT" logo on it, and black axle nuts (see images below).  In actuality, I have seen no stock '99 GT Speed Series Team XL bikes that came with these parts - my stock/NOS 1999 GT Speed Series Team XL bike looks identical to the 2000 GT Speed Series Team XL bike that is shown in the 2000 GT BMX Catalog (image shown below).  I should also note that the seat tube decal that is on my bike is actually for a 1999 GT Speed Series bike - someone at the GT factory must not have been paying attention :) .


I regrettably sold this bike to Museum member LBR 61989 on 7/22/2019.
