KOLOSSOS OVERSIZED DERAILLEUR CAGES
Description
The Kogel Kolossos OSPW for SRAM T-type rear derailleurs reduces friction and ensures smoother shifts with 100% power transfer. This cage is designed to optimize shifting accuracy and chain retention, crucial for XC, marathon, and enduro riders, and maintains ground clearance similar to the stock cage.
Compatible with a range of SRAM rear derailleurs, including models from the GX, X0, XX, and XXSL lines, maintaining the 14-tooth count on the upper pulley while increasing the lower pulley to 18 teeth, up from the standard 16-tooth configuration.
Note, installation might require a longer chain due to the larger pulleys.
Experience a silky smooth drivetrain
No amount of chain lube or coating can eliminate your rear derailleur's inherent design limitations. The path a chain takes during each revolution requires passing through a chicane of derailleur cage pulleys diminishing your return on each pedal stroke. It's a drag on all geared bikes and why your stock rear derailleur will never perform as efficiently as one with an oversized derailleur cage.
LEARN HOW TO INSTALL YOUR KOLOSSOS
Installation is easy, but does require disassembly of the stock cage.
The process takes roughly 20 minutes, including minor adjustments to the B-screw and limit screws to fine tune placement on the bike.
Frequently asked questions
How hard is it to install a Oversized Derailleur cage?
Installing an oversized derailleur cage is best left to expert level mechanics. Derailleur manufacturers do not support disassembly of the derailleur. For this reason online instructions will be limited.
The installation procedure is also different for each model. Some types are straight forward, with some types you need to disassemble the entire cage and use proprietary tools for the installation. With others you run the risk of having to rebuild the clutch if the parts pop out while you’re happily tooling away. Derailleur failures are typically expensive: the chances of breaking a wheel or a seat stay are probably not worth the risk.
Kogel recommends leaving the installation to a professional.
How hard is it to install a derailleur cage
This depends on the derailleur model. Some require special tools, others can be done with regular allen and torx keys. Please have a look at the installation video for your model for the specifics.
Will my existing chain work?
Probably not. Installing an oversized system demands a longer chain than the one used on a stock derailleur. The longer cage and larger wheels create a need for additional chain links.
Will I notice a difference in performance?
Yes and No. Kolossos has been designed to shift just as accurate as your stock derailleur cage. You will notice reduced drive train friction. Upgrading to an oversized derailleur cage is one step in the eternal search to go faster with less effort.
Are Oversized Derailleur cages noise?
The only sound you will hear is from using aluminum wheels instead of plastic. Aluminum wheels are stiffer and more durable than their plastic counterparts at the expense of a faint rattle when the chain runs across the cogs. We like to call it the sound of speed.
What are the downsides to an oversized derailleur cage?
- Every installation requires a new chain
- A slight reduction of ground clearance due to the longer cage
