re: fit.

It is a BIG deal. I almost sold my Swift, when I had too long of a stem on my drop configuration. Thanks to SygInt, I didn't. I just bought a new stem, and poof--back to a super nice ride!.

re: brake levers

Just look for any "long-pull" levers. I use tektro LP brake levers, and they work great (Tektro RL520). However, you may want to consider LP TT levers on yours.

re: front fork

I think that XootrSwift reported success with the Meks/Saso suspension fork.
