Huge crack in my 2007 paragon. Luckily trek is giving me a new 2011 paragon frame! I'm interested in buying a new fork for it. (As opposed to my 5 year old 100mm reba.) When I look on Trek's websie, it says that the paragon comes with a Fox F100 RL 29 w/E2 steerer, custom G2 Geometry, 51mm offset crown, 100mm travel fork. What the hell is that? Is it only available OEM through Trek?

Ideally, i'd like to put a 110mm or 120mm fork on the new paragon frame. Slacker sounds better, to me... Any thoughts? And what steerer do I get? I didn't think there were choices other than straight and tapered. What is E2?

So it looks like my 5 year old reba will not fit on the new paragon frame. (I think.) Any ideas of what else might not swap over.

I know there are a lot of questions here. I appreciate your help in advance.

You can still use your Reba. You might need a different baseplate but should get a new headset with the new frame. The G2 offset crown puts the fork out in front a little bit more. You also might need a new bottom bracket. What crank is on the bike?

Your fork will fit.

E2 = tapered steerer tube. Yours has a straight 1 1/8" tube, tapered is 1 1/8" at top, 1.5" bottom. Stiffer frame, stiffer fork. It's easy to put a straight 1 1/8" fork in a frame with a tapered head tube, just need a different crown race which (at least used to) often come with the warranty frame if you ask.

G2: More offset in the crown. Quickens up the steering. Many love it, some hate it. A G2 frame has a little bit slacker head angle than your old Genesis, which made the bike more stable at speed, through rough stuff, etc. G2 fork kept it from being too sluggish in tight twisty trails (per Fisher marketing, though I would generally agree that it was successful at this).

You can get tapered steerer tube forks with G2 offset from Rock Shox through QBP, and I think you can get them from Fox aftermarket as well. Used to be only through Trek/Fisher, but that has changed. See if you can get some time on a G2 fork. If I were getting a new G2 frame, I'd definitely want the fork to go with. I have a regular offset rigid fork on a G2 frame, and while I like the way it handles, it did lower the A-C and steepen the head angle so it's not a true apples to apples comparison. Basically it's a little steeper, and shorter wheelbase than the bike originally was, and being full rigid I don't bomb that bike down rough descents/chunk where a slack HA makes the biggest difference.

NIner Steel Rigid Fork on 2011 Trek/Fisher G2

I too, have a question about Fisher G2 setup. I want slim down my Trek/GF Marlin and was thinking about putting a Niner Rigid steel fork on it. I am not sure how this will work with the bikes setup as it is right now. I have the stock 100mm G2 offset fork on it. Any thought out there?

That's similar to what I'm running, geometry-wise and I've been reasonably pleased with the result. The Niner has got a ~45mm offset, as opposed to the 51mm G2 offset. It's got a 470mm axle-crown measurement; most 100mm 29er forks are in the 500mm neighborhood so you'll steepen your head angle a bit. These two factors, in my experience, cancel each other out somewhat for slow speed, twisty stuff, and I haven't really tried taking rough stuff at speed on my full rigid bike to evaluate high speed through the chop.

Don't know if this will help at all but I had a Fisher HiFi go out on me. Had a G2 fork on it. Got a new 2011 Trek Fuel frame and they slapped the G2 fork on it. It wasn't too much different than when it was on the Fisher and I wasn't sure if I'd like the wheel out in front of me a bit more. After a few trails and what not, I can't complain. Your wheelbase will lengthen up a bit but that can be a good thing. Just takes some time on your bike if you're sticking with your G2 fork on your "non-g2" frame. Once you get used to it, you'll love it.


Oh, regarding the E2 deal. My new frame has a E2 steerer. The fork off my fisher was a normal 1 1/8 (non-tapered). They have a spacer they fit around non-tapered tubes that allow non-tapered forks to fit into the E2 space. Works like a charm and is plenty stiff.
