Kogel has just announced that they’ve entered the oversized derailleur pulley game with the Kolossos. If you’ve read up on the Kogel blog, you know that the company hasn’t been behind the idea that oversized cages were an improvement for all riders. So what changed? According to owner/founder Ard Kessels, that all comes down to stiffness and better shifting accuracy.
Kogel claims that competing oversized cages are more flexible and when combined with lower spring tension, negatively affect shifting accuracy and chain retention. In some cases this may be acceptable, but in instances where crisp & accurate shifting is required, Kogel has always maintained that stock was better.
Enter Kolossos. With a cage that Kogel claims is the stiffest on the market, Kolossos claims to be 3x stiffer than the comptitor’s oversized cage and 2x stiffer than a stock cage. According to Kogel, this should make the Kolossos better equipped for both road and offroad riding making this an intriguing option for gravel bikes.
