    Excellent product, fantastic customer service, and fast delivery. Thank you.

    Worked perfect for my 1/1 hub bearings.

    I used this for my 1/1 hub 15307 bearings and it fit perfectly. I can see this tool being useful for other bearing jobs as well. Worth getting if you're a DIY'er.

    best brake upgrade

    best brake upgrade. Easy install and now have stronger bite with no brake squeal. Before you change your brakes, just upgrade the pads

    Great upgrade!

    This upgrade kit is a must on the maven brakes. I have been running the sram code RSC, which have great modulation compared to the stock Maven bronze which are a powerful brake that lock your tires up with hardly any pressure on the lever.After putting this upgrade kit on the maven brakes they feel a lot more like the code RSC, way more control and feathering of the braking.I am using them on a specialized levo 3 E bike.

    Perfect cranks.

    These really are perfect! Just wanted some shorter cranks. These XT 8150s are Perfection. Easy to install. Not a sharp point on them. Strong and light!

    Trusted Source for My Bicycle Needs

    Thunder Mountain had the high rise handlebars I wanted, good prices, and, as usual, fast shipping. I never hesitate to source my bicycle needs from them.
