All the talk about wide range these days deals with the cassette, but Wickwerks is putting it at the front of the bike, and that could mean major changes (and improvements) to Junior race bikes. Oh, and anyone else that’s been looking to customize the gap between big and small chainrings without sending shift quality into the gutter.
So, whether it’s running their new 53/34 combo or 41/33, with their fast shifting BRIDGE technology and a new front derailleur mount adapter, Wickwerks says they’ve found a way to give you the best of both worlds…
We’ve covered Wickwerks plenty in the past and one thing is for sure, they make nice stuff. First on the list this year is their new 53/34 chainring system. This gives you a little more climbing gearing while keeping the standard 53t. It uses their fast shifting BRIDGE system that quickly and accurately shifts the chain from one ring to another. Even with such a big jump in teeth, they say their system works just fine.
Wickwerks is known for speedy shifts thanks to their unique BRIDGE system, shown below. Above is the relatively unstable support created by pins, which only carries a small portion of the chain.
By contrast, Wickwerks’ bridge runs the length of the gap to lift the chain fully and in a straight line.
For those not in the know, Junior racers are limited to what gears they can race. USA Cycling limits Juniors’ “roll out” to a maximum of 26 feet (7.93m) per crank revolution. This may sound as easy as just blocking a couple of cogs by adjusting the limit screw on the rear derailleur, BUT, they don’t allow that. So when buying a new bike, juniors have to purchase a cassette who’s smallest cog is a 14t (assuming the big ring is a 52t). That is not only hard to come by, but there is little to nothing in existence (that is easily accessible or affordable), in 11 speeds. The 9 and 10 speed cassettes that are available are also heavy. This means buying a new bike with 11 speeds isn’t at all convenient.
So, Wickwerks developed a 41/33t chainring system that works together and can use just about any standard off the shelf cassette. That includes an 11 speed, light-weight 11-28 SRAM Red cassette. When you consider the convenience and the ability to use lighter weight parts, saving up to a half pound or more, it’s hard not to say every Junior should have this.
They even make a front derailleur adapter to bring the cage down low enough for it to work properly.
