Here’s some more from Trek World in the lovely Austrian town of Mayrhofen…
With 120mm of DRCV-controlled travel front and rear, the 2012 Rumblefish aims to convert existing 26” wheel riders to 29” wheels, as well as provide an upgrade for those already on the wagon. Although Trek make the 140mm Roscoe for the US market, they feel that might be a step too far for the 29”-ambivalent UK market so are starting smaller with the Rumblefish.
It’s available with two spec levels, Elite and Pro, which share the same aluminium frame and have DRCV front and rear. Wheel packages have been beefed up a little with 142x12mm bolt-through axles, and oversized hub flanges & end caps to increase contact, reportedly making them stiffer. Again, production versions won’t be here til autumn but the Superfly 100 we rode was lots of fun, if noticeably (and probably unsurprisingly, as it’s an out-and-out XC race bike, not a trail bike) more waggly through Austrian rock gardens than the Fuel we’d been riding beforehand. Hopefully the Rumblefish will match the good bits of this with better trail-munching ability.
