Qnium products

Looks like incredible engineered products, both the thumb brake & the rear master cylinder. On the master cylinder, be aware QNIUM use 6mm bolts where as the stock Triumph 675 bolts are 8mm. Not a big deal, just be aware.

If I could give Mark and his team a higher rating, I absolutely would. They are, without a doubt, the most knowledgeable and client-focused sales team I have ever worked with. They genuinely care about the people who place their trust in them and consistently go above and beyond to ensure all of my questions are answered. Their professionalism, expertise, and commitment to making sure I feel confident in every purchase set them apart from everyone else.
