This upgrade is amazing. Everything you need to go wireless. Easy set up and precise shifting, smooth and quick. Doubt if i'll ever go back to cable/housing.

Thunder Mountain Bikes is my go place for on-line purchases. They always have what I need at great prices and extremely fast shipping. If Thunder Mountain and “Shop X” have the same price, I always choose Thunder Mountain for their fast shipping plus everyone that works there are great people

Smooth hub and great wheel for trail riding!!

These are the best crank boots, use them on all my Shimano cranks.

Shimano quality as usual, 5 stars.

Love how this adapter cleaned up the cockpit with my Shimano I-Spec EV brakes.

Love the grips

The stem was exactly what I expected. The service was great and I would gladly do business with Thunder Mountain the next time I need more bike stuff!

This replacement charging port cap works great! Unfortunately, replacing it on an Ari Nebo peak required me to take it to a bike shop to get it replaced.

Awrsome service as always

Fit, seem pretty robust.
Turbo Levo4 Pro.

Only disappointment is that they sold out.
Heavy duty, right angle works with any USB C device.

Takes pressure of the weaker part of your pedal stroke. Great for long rides to save your knees!
