This provides a convenient way of attaching thumb lever throttles, CA Aux Input controls, and buttons/switches to your bike without needing to slide off your existing grips. It also lets you attach these devices to curved drop bars or recumbent bikes and trikes with unusual bar geometry. Made from black anodized aluminum, sold as a pair, includes cable ties. Review: Sturdy and easy to mount - These or a product like thisbhas been around for many years in the recumbent world, way befor ebikess. They are great to mount a light on the front post of a tadpole trike (bicycle) and that was my reason to purchase. Sturdy and easy to mount. I do believe they are slightly overpriced however and the company should off the sale of one, not force you to buy two. Honestly, you could make one out of any pipe and a dremel butbit wouldnt be Cnc'd and perfect like these. You gotta put some rubber between your bar and this to help it not slip Review: Very useful - A must have for dropbar e-bikes. ## Features - Extensions for Attaching Throttles and Buttons to Curved, Oversized, or Unusual Handlebar Geometries ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B078T5S7YV | | Best Sellers Rank | #531,670 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #630 in Bike Handlebars | | Bike Type | Road Bike | | Brand Name | Grin Technologies | | Color | Black | | Customer Reviews | 4.4 4.4 out of 5 stars (16) | | Item Dimensions L x W | 0.87"L x 0.87"W | | Manufacturer | Grin Technologies | | Material Type | Aluminum | | UPC | 628461000218 | ## Product Details - **Brand:** Grin Technologies - **Color:** Black - **Manufacturer:** Grin Technologies - **Material:** Aluminum - **Product Dimensions:** 0.87"L x 0.87"W ## Images ![Grin Technologies Handle Bob Adapter For Attaching Ebike Throttles and Buttons to Road Bike Drop Bars, Curved, Oversized, or Unusual Handlebars - Image 1](https://m.media-amazon.com/images/I/41dAcxMCCfL.jpg) ![Grin Technologies Handle Bob Adapter For Attaching Ebike Throttles and Buttons to Road Bike Drop Bars, Curved, Oversized, or Unusual Handlebars - Image 2](https://m.media-amazon.com/images/I/61p9TizO0dL.jpg) ![Grin Technologies Handle Bob Adapter For Attaching Ebike Throttles and Buttons to Road Bike Drop Bars, Curved, Oversized, or Unusual Handlebars - Image 3](https://m.media-amazon.com/images/I/61Dp5hiMU9L.jpg) ![Grin Technologies Handle Bob Adapter For Attaching Ebike Throttles and Buttons to Road Bike Drop Bars, Curved, Oversized, or Unusual Handlebars - Image 4](https://m.media-amazon.com/images/I/51XyvZplBOL.jpg) ![Grin Technologies Handle Bob Adapter For Attaching Ebike Throttles and Buttons to Road Bike Drop Bars, Curved, Oversized, or Unusual Handlebars - Image 5](https://m.media-amazon.com/images/I/51XV2vSQMHL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sturdy and easy to mount *by A***R on July 14, 2025* These or a product like thisbhas been around for many years in the recumbent world, way befor ebikess.
