“The only tool that can do the job, bad shifting on 4 bikes solved in about 20 minutes, was painful to part with the $80 but to have a shop do all 4 bikes would have been $200 so glad to have another well built and intuitive to use tool in my box. Built like a tank”

“The gauge worked great, and was necessarily rigid. The run out was minimal, and the components had expectedly tight tolerance. Snapped my derailleur hanger clean in half once I went to adjust it, but that's probably a skill issue.”

“This derailleur hangar straightener is a pro shop level tool. Kind of overkill for this occasional DIY bike mechanic. But I have two e-bikes, both which needed the frame hangar adjusted. This tool and the helpful videos saved me the cost and time of loading up the bikes and taking them a hour away (nearest bike shop). And it will go with me on bike camping trips (bike stand too). That is the purpose of a good tool. Your focus is on correctly aligning your derailleur not on fiddling with the tool to do it. Highly recommend.”
