These 6 piston mechanical disc brakes from JuinTech might be the most powerful ones I've ever used, but can they justify the incredibly high price?

I have always had a soft spot for mechanical disc brakes on road bikes. They’re simple to use, easy to setup and maintain, and you can make use of older mechanical groupsets, so are great on more budget oriented bike builds.

I have tested A LOT of different ones in my time, but I've never seen anything like the JuinTech GTF6. It’s an expensive, oversized mechanical caliper, with 6 brake pistons, that also makes use of large brake pads from an obscure MTB groupset.

So in order to properly assess the performance, I'm going to pit the GTF6 caliper against the two other mechanical callipers JuinTech offer, the 2 piston F1, and the 4 piston GTF.

In short, the braking performance was pretty phenomenal, but in light of other options on the market right now, for the average road cyclist, they are just too expensive. Plus, if you watch the bonus clip, the TRP HY/RD calipers are still my favourite!
