Shimano Alivio M3100 Series

Great service

great products and service. very solid!

XO1 mechanical is a proven workhorse. TMB always gets my orders out fast and without hassle. My go to online source these days.

Needed a replacement for my stock XT brake line and this was first on my list. May be the exact same one but the gold looks cool with all my other gold. Thanks Thunder Mountain!

Fast shipping, color as stated, happy guy here

I went with the new XX Eagle Transmission crankset with power meter. I was mixing with SRAM Eagle AXS transmission (derailleur, chain, cassette, shifter) so purchased the Wolftooth chainring in a “0” mm offset to keep the chain line right (3mm offset chainring comes with w new Transmission crankset and T-type drivetrain). The o mm offset shifts like a charm. Power is accurate. Moved from 175 to 170 crank arm length and love the entire set up. Customer service was great. Got advised on the chain ring purchase.

Shipped fast and packaged well im stoked

Good price
Would buy again .

Good price, great products

It’s really hard to find smaller size cranks to fine tune your build,I’m 5,5 so with the smaller frames coming with 170 cranks this 155mm cranks are a game changer thank you

Great pads! I love the compatibility charts for the components! Fast shipping!

Love a new cassette, especially one of this caliber.

Awesome set of wheels. With excellent customer service and shipping was super fast.
