    Titus Ti Fireline EVO 29er: Reviews? Anyone running a 100mm fork?

    I really like the looks of this frame, the geometry, weight, price, etc. I'd love to see sliding dropouts on it, but I digress. I have a 100mm fork that I want to run on my next bike. Is anyone running 100mm on this frame? If so, how is it? I'm also curious about overall reviews of this frame. How does it compare to other bikes? Strengths, weaknesses, etc?

    I also noticed that there is no wheelbase on the geometry summary on On One or Planet X. Is there anybody from Titus out there that can clear this up? Also, I would love to know the Titus party line on a 100mm fork. Thanks.

    I spoke with someone from Titus yesterday about whether or not the Fireline EVO 29 could be run with a 100mm fork. He basically said "no" b/c the bottom bracket would be too low. It is interesting, however, that it would be similar to the Pivot Les, at least by my calculations, that is, about 12.1in static. Here is my calculation, the Fireline has a 12.4 static bb height w/ 120mm fork and w/ sag, it is 12.1in or 2.4in bb drop. The sag should be about 20-30mm which would be equal to a 100mm fork static. Does this make sense?

    I do not hear complaints about pedal strikes on the Les reviews. Also, Niner SIR 9s and the Air line have a BB drop of 2.4in when run w/ 80mm forks. Finally, I'm running my SIR 9 with the niner carbon fork which is comparable in A-C length to 100mm forks (although no sag) and I prefer to have my EBB in the low/rear position. The offset of the EBB is 8.5mm. All this makes me think that 12.1 in static is doable and would provide a nice low-slung, quick cornering, nimble ride. Of course, this all depends what trails you are riding and your sag.

    Does my reasoning above make sense? Anyone want to work out math problems for the rest of your day? Maybe more importantly, has anyone had problems w/ a BB height of 12in or so or BB drop of ~2.4in? Am I spending way to much time on this? Should I pick up the crying baby in the other room instead?

    Finally, if you look at how the static numbers would change on the Fireline with a 100mm fork (similar to the "riding height" numbers for the Fireline with 120mm fork), it starts to sound a lot like the static numbers for the LES. The HA would be ~69, SA ~73, CS 17.1, BBH 12.1. A titanium ride with similar geometry to the LES for under $1000 sounds pretty appealing. Am I reaching here?
