The trickle syndrome works boths ways. In favor of consumers new technology is eventually normalized and prices drop while actual utility remains constant. In the other direction, it can convince us all that we need HDTV, that our new DVD players are inadequate, that a new fridge is better than your old one and that carbon fiber pats are reasonable on an enthusiast bicycle.

They’re all crazy.

Here are three prime examples from Interbike that show off much of what is becoming a pretty fast trickle.

In order; Giant Yukon FX, Jamis Dakota Comp, Marin Alpine Trail 29

Giant Yukon FX - $865 buys an aluminum framed full suspension design that makes sense with 4in of adjustable travel front and rear. SRAM 8speed shifting, mechanical disc brakes. The entry level isn’t so bad anymore - they go, they stop, the suspension actually works. Nah, it ain’t light or particularly performance driven, but its better than even the highest end was a mere few years ago.

Jamis Dakota Comp - $1350 price tag on a race driven frame. Aluminum main frame, carbon stays. New XT Shadow rear deraileur, 4″ travel fork, hydraulic disc brakes and name brand components throughout. Buy it and race it that afternoon at a price that used to just cover a set of hydraulic brakes and a decent fork.

Marin Alpine Trail 29 - Hydroformed aluminum frame and 29″ wheels, all for $629. Crazy. Even just a couple of year ago there was no one making a 29″ suspension fork. Now you can get an entry level one to experience the ride without dropping the big dollars. Its 8speed with mechanical discs and should do for most everything.

Suspension, racing hardtail, and a niche 29er all at prices that are a bit easier to swallow than most of the bikes under the hot lights.
