I owned an MS Racing CR2 but totalled it into the back of a car. It was a fantastic frame, really stiff in the main frame but with a softer back end.
An interesting feature that I've not seen revealed anywhere is that there was a steel tensioning rod which ran the entire length of the inside of the down tube with spoke nipple style heads at either end. I would guess that the tension rod was added to increase the tensile strength of this key element. I know because mine snapped it's head tube off! If I recall correctly, the MS Racing frames were made from a 2000 series aluminium alloy rather than the 6000 and 7000 series alloys most other manufacturers were experimenting with. I'd replaced the forks with PACE RC-30's
When I snapped it, I replaced it with an Alpinestars Al-Mega XT! PACE kindly fabricated a 1 1/4" one piece stem and a crown and I ran PACE forks in that too.
Of the two, I always preferred the ride of the MS Racing. Sold my Al-Mega on in early 1991 and switched to a Scott Pro Racing!
