Review: Top notch quality tool - Quality tool but it is expensive. You get what you pay for…unless it’s a montblanc pen refill!
Review: TORQUE SPECS FOR THIS TOOL NOTICE - Please Note: - Some of the reviews here quote Sram Dub Torque specs of "50nm" for this tool..(and showing a damaged tool) THIS IS INCORRECT - that torque rate relates to the Crank Bolt and NOT THE Bottom Bracket Cups that this tool is for. The BB Cups have a much lower 35-40nm spec (NOT 50+nm) - This tool is fine so long as you use the right torque specs for your Bottom Bracket - Please review the documentation that relates to your Bottom Bracket model and check your specific torque recommendations.
