Hi All,
Manufacturers have introduced a number of new products at this year's Cologne Bicycle Show. Among them, Shimano have announced 2012 will see the introduction of a Deore group with 10-cog cassettes instead of nine. Campagnolo seems to be moving ahead with electrically-actuated shifting, as is Shimano on some of their racing-oriented lines. Tout Terrain have further refined their "Plug" series of USB charging ports for dynohubs, and so forth.
The past decade (or more!) has seen a steady refinement of bicycle components brought to market, and some genuinely new twists (though some were introduced decades ago and beautifully illustrated by Daniel Rebour). Among these are the threadless headset and external-bearing bottom bracket, which -- together with pinch-bolt cranks and large-diameter, captive BB spindles -- have made life easier for touring cyclists, who can now perform needed service with only a 5mm allen key. Perhaps one of the greatest refinements for adventure cyclists is the Rohloff hub. It surely has made a positive difference in cycling pleasure for many, both through ease of use and greatly reduced maintenance as well as increased reliability and reduced overall costs, despite the huge initial outlay. Disk brakes (both mechanical and hydraulically-actuated) are now in widespread, popular use as well, but were entirely absent from the market 30 years ago. Same for carbon-fiber frames and even aluminum and titanium, 40 years ago.
So...
Given these trends, use your crystal ball and tell us where you think bicycles and their components will be heading in the years to come. Historically, racing has been a driving factor in weight reduction and product refinement and innovation. Years ago, French reliability trials did something similar among French tourists. Where and how will future innovations help or hurt the casual or club cyclist, the randonneur or audax rider, the tourist or globe-trotting adventure rider?
How complicated should bicycles become? Will electrically-actuated gears ever be appropriate for back-of-beyond cyclists, or are cables and housings the most appropriate technology for such use? Will the chain survive as a way to transmit power, or are we headed toward widespread acceptance of toothed belts? Will we ever see a practical "plastic" heavy-touring frame? Keep in mind, it would not be a huge trick to integrate racks and even panniers with proper molding and forming techniques, and wiring runs could someday amount to printed circuits laid as part of a composite frame material, with super-capacitors integrated as part of the design to give "standlight" capability to a number of gadgets. I've always wondered how the hollow space in frame tubing could be put to better use; what a great place to carry...something! Will we be seeing greater adoption of suspension designs for cycle-tourists? Will tires still be rubber-based or go more to plastics and fillers? I saw mention of a design for a self-inflating bicycle tire the other day; why not?
Let's hear it -- where are we going, is it appropriate, and what will/would you like to see? Please specify whether you're predicting the future of cycling in general, or by genre (i.e. touring, audax, casual, racing, etc.) or component design. A prediction free-for-all!
Best,
Dan.
