Blog #005 – Old Guy Training – My 20″ Mosh Expert AL.

Hey Team ….. today I thought I would bring you my main BMX (at the moment) ….. my Giant Mosh Expert AL.

Mosh BMX  was a division of Giant Bicycles ….. Mosh BMX was created back in 1996 with the help of Linn Kastan & AA BMX Pro Rider Jason Richardson.  Giant made bikes using the Mosh name until 2003.  Giant of course has been making bicycles of all styles for many years and had been turning out BMX bikes since 1979 starting with the GMX250.

My Mosh Expert BMX was built in the Giant Bicycles  Taiwan factory in November of 1999 using aircraft grade Alcoa CU-92 Aluminium tubing for the frame of the bike and then fitted with a Spinner brand full chromoly fork using a 1 1/8″ threadless steerer tube.  I am still rolling the original wheelset which is Sun Z19 rims with Giants generic sealed hubs and plain steel spokes. Up front I am running Maxxis 1.85 M-Tread and out back I am running Maxxis 1.95 Ringworm.

Gearing is the usual 44t x 16t using the original Giant chainring but have swapped out the original Giant one piece crank for a later model Giant Method 02 – 8 spline / Euro bottom bracket and axle with Giants 175mm tubular three piece cranks. Did this swap purely for the ability to run 9/16″ SPD pedals as the original one piece crank was still running 1/2″ pedal threads.

Steering is from the original Mosh Steel bars via the original Mosh Billet Al stem withsome generic BMX grips. Braking is good old Tektro V brakes running a right hand lever.  The forks on the bike are actually Spinner brand full chromoly forks from a 1997 Mosh Pro XL. These forks are almost 500gms (half a kilo) lighter than the original forks and well worth the weight saving considering that for now I wont be pulling any huge air stuff hahahahaha.  Since this post I have swapped out the original Mosh steel bars for some other bars which are a little lower and a little narrower and a lot more comfortable than the Mosh bars.

Some of the unique features on the bike are the threaded sliding dropout chain adjusters which I believe only came with this years production run and were at the request of the team riders ??       ……. other unique features were the elongated top tube which runs right through the seat tube junction and allowing the seat stays to join the top tube south of the junction as well as the heavy duty bracing of the headtube / downtube junction at the front of the frame. The 58mm down tube is massive by any BMX era standards, add to this a 44mm top tube and a fully gusseted bottom bracket chainstay junction and all this adds up to a super stiff and strong frame that can take a load of punishment.
