I have a 2012 Rumblefish base model that I upgraded with a Dynasis XT package and carbon wheels. Great bike. Rarely ride my Yeti ARS575 any more.
One problem. I take the front wheel off to load onto my bike carrier and often the plastic hub insert falls out, usually in the dirt, and I have to clean it up and replace. The o-ring is supposed to keep it in place but doesn’t do a good job. Also can fall out when the tire is stored inside the vehicle during travel.
Any thoughts?

I rode at the Trek Demo here in Omaha on October 15, 2011. I tested the Fuel EX 9.8 Carbon first. I was thinking of something that does it all for a bike. Ran the trail and I wasn’t impressed personally. The suspension was better than my cheap bike that I have now. Other than that, not a huge difference and didn’t feel right.

Then, I tested the Rumblefish II Pro (what I really wanted to ride). Same one here. HUGE difference. I rode the same trail and shaved almost three whole minutes off of my time. It handled like a champ. The bike just went where I pointed. Suspension felt amazing and climbs and dives were great! It was as if someone studied me and made a bike to fit just me. This is what I’m getting. Once I tasted 29er’, I can’t go back.

Got to demo the 2011 version of the Rumblefish earlier this summer. It was the first 29er I had ever ridden and felt completely different than I was expecting. I expected something slow, heavy, and unruly in tight spots. I came away so impressed with the ride that I’ve decided to get rid of one of my existing 26″ bikes and make the FS 29er leap. Now it’s just a matter of riding enough bikes to make an informed decision.

Trek7k, having ridden a number of 29ers, do you notice the proclaimed benefits of the G2 geometry that the Gary Fisher bikes use?

I haven’t been able to ride many 29ers but, in my limited experiences with them so far, I haven’t really noticed a huge difference in the handling characteristics from the GF G2 geometry to that of other brands.

haha, don’t even get me started on claimed weights. Some road bike manufacturers (it was either Cannondale or BMC I saw doing this) are using some sort of ‘correction factor’ to advertise a comparable weight. So the add says something along the lines of “XXXg size-corrected weight for 56cm frame”. What a bunch of crap.

Sometimes “claimed” rear wheel travel and “actual” rear wheel travel differ. The company runs the numbers and mathematically it ends up being one thing, but real world application differs.

Sorta like how no matter what a company says a bike weighs, it always seems to weigh more when you put it on the scale…

Hmmm… What’s interesting is the Trek rep actually said the bike only has 100mm rear travel – I got the 110mm number off the Trek website because the 100mm # seemed so strange to me.

What??? 2012 RF has 120 front and rear, at least from what i have heard. I know that the 2011 is 110 and they wanted to change that. I’m going to e-mail trek now!

check out specs.
