I'm working with steel frames at the moment, but most Alloy frames I have checked out are good and can't wait to build on Allloy.
Bike shops are in buisness and are not going to endorse motoredbikes, we are on our own. We can survive in the long run with low profit and high turn-over.
They are in established networks or franchise and work on exploiting demand.
Which makes it unafordable to many commuters, so we motorbike it !
What other choice is there ?
