>>2009128I am waiting to hear back from Montague about the ability to buy a standalone frame. The Montague Allston roadbike comes with the belt and a seat stay splitter to be able to attach that belt. The other frames don't have that option so that's the only frame I could get (I just recently confirmed this after posting my original question here.)
I'd also want a suspension fork that can handle 700c wheels, so I'd order from Rockshox, which is the brand on Montague mountain bikes. I would also want handlebars with drop bars but don't know what would be compatible yet.
I am insistent on a folding bike because I want to use it for packrafting where I take the bike with me on the raft. Montague specializes in folding bikes, so I expect to be able to get high performance out of this.
I see that the Gates carbon belt drive thar comes with the Allston has a front sprocket with 46T and a rear with 24T. That front sprocket comes in 46, 50, or 55T options. The rear comes in sizes ranging from 19T-39T. This is where some of my remaining confusion is.
46T front : 24T rear = about 2:1 gear ratio. The Alfine 11 internal hub has a lowest gear ratio of about 1:2, and a high of 2.15:1.
So I wonder, does an external sprocket 2:1 fixed ratio stack up (might not be right word) with the ratios of the internal hub?
Would first gear (1:2) feel more like 1:1 since the external sprockets begin with a 2:1 ratio? And would the top gear be more like 3.15:1 rather than 2.15:1?
Knowing this would be helpful in determining whether I should buy a 55T front sprocket crank set and possibly a smaller or larger rear sprocket.
It also says nothing on the Montague website about the length of the belt included with the Allston, but Gates belts come in sizes from 108-183T.
