When you buy a cycling accessory such as a computer or light it often comes with a handlebar mount. You may not think much about it, but by and large, these stock units don't work all that well. Thankfully there are brands who make excellent aftermarket solutions. Think K-Edge and now a new company called FormMount.
The arms are made from injection molded carbon or Kevlar reinforced nylon, which has been over-molded over stainless steel sleeves for strength.
This Kickstarter project directly mounts to a four-bolt stem via either the two higher or lower bolts. This is achieved using longer hardware and small spacers. The mounting arms are also adjustable, so they are compatible with stems that have tight or wide bolt spacing. The arms can be mounted in five different positions, so you can choose from over the stem, in front, below, and so on. It's a highly modular system.
The cradle/mounting area is made from Delrin, a low friction nylon. This material is claimed to reduce engagement wear on accessory mounts.
The mounting interface for accessories is equally capable. The design allows you to double up accessories, so you can mount both a GoPro and light. There's also options for your phone and computers of various sizes.
The FormMount is currently available for pre-order through Kickstarter. A unit retails for $45 and includes one set of arms for small/medium computers, one set of longer arms for large computers, a GoPro camera bottom cradle, three pairs of spacers to customize fit, and a pair of stainless steel M5 bolts.
