Juintech ETF calipers

[dsveddy]

Juintech have released a flat mount 4-pot caliper. Some notes of interest:

-extended mounting points to eliminate rear brake block
-one piece construction
-75g and $180 per caliper 
-available on Aliex and Amazon Prime

These are the lightest, but also nearly the most expensive caliper on the market. It’s a similar concept to the Hope RX4 caliper, but are nearly $50USD more expensive.

Overall interesting to see these brands enter a new era where they are positioning themselves as the premium boutique option.

This thing has been out for over 6 months. The combined surface area of the pistons is smaller than most mainstream brands' 2 piston offerings. So they offer no extra stopping power and open up the possibility of uneven piston operation and just overall worse reliability and quality of life.

They released a 2 piston etf-a caliper two weeks ago, weighting 71g a piece. Still basically impossible to buy and no specs, but those pistons don't seem too big either

Installed it on my TIME Alpe d'Huez 2025 and they are really light and stronger brakes compared to the stock Shimano Ultegra calipers - JuinTech ETF 4 pistons brake calipers and RTZ-01 Rotors.

They look nice but I wonder if they're worth the price premium over something like the IIIPro XG4.

First real hard test of these calipers on the descents of Sa Colabra and San Salvador climbs in Mallorca. The former is long winding and sharp while the latter is loaded with corners coming down from the hilltop monastry.

I upgraded the pads to SwissStop 27s and they offer better bite IMO to stock pads. Also I swapped out the RTZ-01 rotors for IIIPro A2 rotors which could only take on Resin pads etched on the body.


All I can say is the bite is pretty firm and no way I felt any fade or vague contact with the brake pads. That gave me a confidence boost coming down the fast descent of Sa Colabra and technical corners of San Salvador. I am never a good descender but the boost helped me improve with confidence with each corner completed. Now I am firmly behind this solid brake caliper's performance once the alignment is properly done.

Built my new TIME Scylon with Juin-Tech ETF calipers with IIIPro Ultralight rotors (160mm) - the successful combo testing in Mallorca on my Alpe d'Huez.
