The Rans has been reduced to 800, the Thunderbolt is 850. Financially, at this time, I really don't want to get further into recumbency.
Assume I can't test-ride either one. I have to make a decision based on a test sitting and theory.
I am 5'9, 220. Not fat, marbled. <g>
When I sit on the Rans, I'm way back. There's not enough room on the main tube to put a clamp behind the seat slider. I'm thinking that that front wheel is going to get light during acceleration, given how far back I am.
Brummer makes the argument that there is a sweet spot--a position of optimum weight distribution between the front and back wheel--that the rider shouldn't muck with. Hence the fixed seat and the sliding boom. If he's correct, I could be in for big trouble on the Rans.
Also, when I sit on the Rans, the seat feels comfortable but small. Over time, it'll probably get smaller, if you know what I mean. The Thunderbolt's seat will accomodate the Mighty Kong.
The downside to the Thunderbolt is that cheezy crank. I would definitely keep my eyes open for a sweet deal for a BB/crankset upgrade.
Hills aren't a consistent issue for me.
What do you think?
