20% OFF - OLSEN Charlie Extension Stem
The Charlie Stem gets its name from MTB Hall of Fame, Frame builder Charlie Cunningham.Â The shape is inspired by the old gooseneck LD stems by Ibis and Cunningham, but with a few accommodations for modern bike needs.
1 1/8" threadless and 31.8mm handlebar clamp with a removable faceplate. With 145mm of vertical height from the base of the stem to the center of the clamp, it's pretty useful for getting your handlebars up high without using a ton of spacers.
This only comes in 70mm Reach Extension - with the extra height there is no need to reach out.Â Ideal for those who want to sit up, look around and take your time.
The Charlie functions as both your stem and top cap.
Your star-nut should be approximately 1cm from the top of your steerer tube and you need at least 55mm of tube (metal only, not for use with carbon steerers).
Now slide your stem on the steerer, slip in the long bolt with the washer, pretension with the long bolt, and clamp it down at the base.
Use grease as needed.
