The Superior Shifting with Junior Road Gears
These are the chainrings of The Junior Solution — WickWerks answer to Junior Road Gearing Requirements. Read the article to understand the many benefits for Junior road racers participating in sanctioned races. These chainrings and the associated FIT LINK solve most junior gearing restriction requirements for road bikes. This is the revolution in meeting Junior Gearing needs.
BRIDGE Technology Road Double Chainring Set:
– 41/33 Teeth
– CNC 7075-T6
– MIL Type 3 True Hard Anodize
– Weight 104 g (Ring Set), Varies by Crank Type
– 110mm BCD, 4 or 5-Bolt versions for the various crank types.
– Most models and manufacturers (See Crank Types Tab above.)
– 10 & 11 Speed Compatible
– Use with 11-(X) Cassette for Junior Roll-out*
Note: Check actual roll-out measurement on the bike to be sure. Don’t rely only on calculations.
Note: Some governing bodies have different roll-out rules. Check your applicable rules.
– Most Road Bikes with braze-on mounted front derailleur will require the FIT LINK adapter for proper positioning.
– May not work with all bikes. Read “The Juniors Solution” for product limitations.
Junior Roll-Out Gearing Limits
Junior gear restrictions were implemented to help juniors learn to ride tactically by keeping early developers (strong kids) in the pack, and to limit joint tension by having them learn to spin faster instead of pushing the pedals so hard. Whether reduced gear sizes accomplish that or not is up for debate, but most US sanctioned road races will have Junior Gear Restrictions as defined by USA Cycling. (Most countries have similar rules, check with your sanctioning body.)
Roll-out is defined as the distance a bike travels in one full pedal revolution when in its highest gear. This is usually measured by pushing the bike backward (so the pedals turn with the wheel). In the USA (and many countries), the roll-out distance is 26′-0″ (7.93 m). Note: Check your local rules.
There are numerous ratios that will accomplish this, but there are definitely limits to finding the right ratios with available hardware. Another source for info is Life on The Bike.
Enter WickWerks and The Junior Solution
At WickWerks, we support Junior programs, and we have a set of chainrings that will be legal in most Junior road bike set-ups. Not only are they legal, they optimize function (and cost), and solve several common issues. Read More
For a bicycle equipped with typical 700C x 25 tires and a 11t small cog on the cassette, our 41/33T chainring set provides a 3.667 ratio; and an estimated roll-out distance of 25.67 ft — just shy of the 26 ft limit. (Calculated) Note: calculations are good, but distance rolled out is the governing standard. Tire size and other factors contribute to the actual roll-out distance.
As mentioned, there are lots of ratios that meet roll-out limits, but the constraint is usually finding the equipment. Tire size can be one of many. The 700C x 23 is popular, but 700C x 25 and other sizes are available and nice for certain situations. Cassettes are available with various tooth counts, but the 11-(?) are most common — like 11-25 or 11-27 or 11-28. Paired with our 41 tooth big ring, the 11 tooth small cassette cog is a great ratio (making a 41 to 11 top combination) and will be legal for most bicycle arrangements.
The WickWerks Advantage
Often, rings sized for Juniors don’t shift well. That is troublesome for kids in racing situations. It is also troublesome because they don’t learn the valuable advantages of knowing how and when to make that front shift — because they become afraid it won’t work — so they just stay mostly in one ring and “slog” through it.
The Junior Solution is WickWerks answer. This is an integrated approach that include the chainrings, and, the “Fit Link” required to mount the front derailleur properly with the small chainrings on bike frames equipped with a braze-on mounting tab. At WickWerks we’ve integrated our BRIDGE Technology with all our rings — even these sized for Junior gearing limitations. These are the best, fastest shifting rings on the market — for kids and adults!
Secondly, the WickWerks solution is lighter than most. Compared to the most common combination (52 front – 14 rear), the 41t WickWerks front ring is much lighter. Also, high-end 11-25 or 11-28 cassettes are readily available and all are lighter than the (usually low-end, heavier) junior road cassettes. This combination using WickWerks Junior Road Gears with a high-end 11-(?) cassette will definitely save weight — approx. 300g in some cases — and help your junior accomplish their racing goals.
