Don't most tracks have rental bikes?
You could try that to see if track riding is something that even remotely interests you at all. Because there's a good chance it won't, so making that a big consideration in buying a new frame might be unnecessary.
Seems like you're trying to decide which brand name golf clubs you like before you even play a round.
That is a very good point indeed and yes, the somewhat local track does have rental bikes. I like the golf example, i never really thought about it like that..haha
As goofy as this is going to sound, i just really love the look of the T1 more so than the Mark V Pro too. That is me being 100% honest. But i have seen some really awesome IRO builds too. Decisions decisions...
