I do not have good memories about my Bob Jackson Vigorol track bike. Was attractive but dreadful, only good to come from it was I was able to buy it on time payments, fortunate for a 13 year old.
back then the market was quite imperfect, new frames or bikes were scarce, the used market was almost invisible.

it did prompt me to get an order in on my second track bike, I still have that one.
a different universe of performance.
