58g 18mm Steerer Extender Compression Plug for 1 1/8" Carbon Road Bike ForksThis product is a light weight solution to safely add 18mm to a 1 1 8" carbon steerer. This extender system must be used with a typical 40mm stack height stem so that the lower 20mm of the stem is clamping on the carbon steerer, leaving the 18mm extension plus a 2mm air gap in the upper half of the stem. The steerer must also be cut squarely for the extender to sit flush. A picture of the extender installed in a carbon steer is shown in pic #8. This

This product is a light weight solution to safely add 18mm to a 1 1/8" carbon steerer. This extender system must be used with a typical 40mm stack height stem so that the lower 20mm of the stem is clamping on the carbon steerer, leaving the 18mm extension plus a 2mm air gap in the upper half of the stem. The steerer must also be cut squarely for the extender to sit flush. A picture of the extender installed in a carbon steer is shown in pic #8.

This is a great solution for any bike with a carbon 1 1/8" steerer which needs a just little bit more steerer stack height. Other extender solutions on the market are typically very heavy and have very long extensions which do not allow the stem to clamp onto the original steerer. 

Weight: 58 grams without the stem cap and bolt, stem cap and bolt is 21 grams.

Condition: New.

Warm soft pajamas or lounge wear!
I recently purchased this two-piece pajama set and I’m absolutely thrilled. The fabric is incredibly soft, thick, fluffy and of excellent quality. This khaki color is a buttery honey khaki, its a soothing color. It feels like I’m wrapped in a warm, fluffy teddy bear hug the stitching is impeccable. I love the adorable buttons and pockets on the top. These PJs have exceeded my expectations in every way from comfort, warmth, durability and price. If you’re looking for a cozy high-quality pajama or loungewear set to keep you warm, I can’t recommend these enough. I’m 5’7 and 127lbs I ordered a size M and have a lot of room. Plenty of length. Again Bedsure doesn’t disappoint!

Soft, pretty and cozy PJs
I am 5'3" 140 lbs. and I purchased the size medium, it fits just right. I tried these on right out of the box; they were so comfortable that I didn't even want to take them off to launder them. Of course, I did wash and dry them according to the recommendations and they came out so fluffy, no shrinkage all seams intact. Wearing them is like lounging in a warm cloud. I bought them in the cream and blue colors, the cream color looks just like the website photo. The blue hasn't been delivered yet, but I am hoping that the fit and feel of them is just like this pair. I got them on sale for $19.99, so worth the price.
