Kolossos ST Oversized Derailleur Cage - 11 and 12 Speed 105Kolossos, derived from the Greek word for a statue much larger than its original subject, aptly describes this oversized derailleur cage.

Kolossos, derived from the Greek word for a statue much larger than its original subject, aptly describes this oversized derailleur cage. Replacing your stock pulleys with a ceramic 12-tooth top pulley and a 19-tooth bottom pulley, built on the stiffest cage available, enhances performance by reducing friction and improving shifting accuracy. This design also emphasizes gravel worthiness and chain retention.

The Kolossos ST model offers the same stiff, oversized cage for crisp, accurate shifting and oversized pulleys to reduce drivetrain friction. It is equipped with high-quality stainless steel bearings, providing excellent durability and smooth performance at a more accessible price point.

This model is compatible with Shimano 105 R7100 electronic and R7000 derailleurs, accommodating both short (SS) and medium (GS) cage lengths. Please note that installing this oversized derailleur cage typically requires replacing your chain to accommodate the larger pulleys.

Runs small, great quality
Size: X-Small, Color: White 2-pack
Quality is great but the sizing isn’t what I though. My 3.5 year old (he’s typical size, skinny, not short but not the tallest kid) is in between a 3 and 4T. I bought the XXS and XS. Both were too small! The shirt also seemed like maybe a girls cut, the sleeves were short and it seemed to have a bit of a curve on the sides like some girls clothes do. I still gave 5 stars because they are really nice shirts for the money.

Value for money
Size: Medium, Color: White 2-pack
Good quality, material is thick and soft. Runs a bit small so I would rather size up next time.

Favorite White Tee
Size: Medium, Color: White 4-pack
Love these simple white tees. They don't shrink and are adequately sized. They wash well. My 6 year old loves them too. Light and comfortable. They can be dressed with jeans, shorts, work as an undershirt or pajama shirt. Favorite white tees for any outfit. Excellent priced. Great shirts overall.
