These pedals have been tested on rocky, rooty, and uneven terrain and can withstand the punishment. 2. WIDE APPLICATION: The pedals' thread spindle uses the international universal standard 9 or 16 inch, suitable for 99 percent of bike cranks, such as mountain bikes, road bikes, folding bikes, and commuting bikes. Each bike pedal spindle is fitted with 3 sealed bearings, which spin smoothly. 3. STURDY AND DURABLE: The bike pedals are made of full titanium, which is sturdy, abrasionresistant, and corrosionresistant. The 3 sealed bearings are lightweight, lubricated, waterproof, and dustproof, effectively preventing dust entry, improving pedal stability, lubricating, and saving energy, and are durable. 4. GREAT GRIPS: The lightweight and wide base make it easier to keep your feet on the pedals when climbing, providing a more comfortable riding experience.
