What Our Gearhead(R) Experts Are Saying: "I've used these on long-course training rides, and the 15mm thickness really helps reduce pressure on the elbows. The foam holds its shape well over time, and the updated surface pattern adds grip when things get sweaty. Solid upgrade for anyone running F-35 armrests."When we're locked into aero and chasing steady watts, comfort can make the difference between holding position and sitting up. The F-35 Ultra Pad 15mm from Profile Design delivers a broad, supportive platform that helps us stay planted and focused through long training blocks and race efforts. Designed with a large surface area and contoured edges, these pads relieve pressure points while supporting elbows in aggressive positions. The moderate 15mm thickness balances cushioning and control, making them versatile for both daily training and race day. Updated foam resists long-term compression, maintaining support ride after ride, while the molded textured surface enhances grip and helps wick away sweat. Fully compatible with F-35 armrest kits, they're a dependable replacement that elevates aero comfort and stability.
