Shimano Alivio M3100 Series

Awesome seat excellent quality and thunder mountain delivered as promised will continue buying from you

I am getting back into mountain biking after a long, long while and the tires on my old bike weren't in bad shape, but not great either. Some friends and co-workers told me about these and so I gave them a try. I am very happy with the traction and sidewall stability relative to my current style of riding and capabilities. That's about all that I can say :)

Finally made it to Sedona to mtb vs hike. Bucket list adventure for me. I was so excited to check out the trails with my buddy. Barely 10 mins into our ride I had a ride ending mechanical issue. I remembered seeing a post recently on IG about Thunder Mountain bikes so I headed right over. They were busy as expected and had bikes in the stands being serviced. I explained my issue and they said it might be a couple hours to get to it. I said I completely understand. Unfortunately I didn’t have a couple hours. Contemplating my next move…tech said…Hey man let me take a quick look and see if I can get you back on trail. He was able to quickly replace my derailleur hanger (I provided, always carry a spare) and straighten out my derailleur enough to function/shift pretty darn good. He said if you’re chasing perfection I’ll need more time. I completely understood and was so stoked that my day wasn’t over. Headed back to the trail and completed the loop we set out to ride. So thankful for the level of customer service they provided. I didn’t beg or even share my schedule with them. I knew they were busy and respected that. Top notch service. Thank you for helping me have a great day on the trails.

Best crank set I’ve used, solid, light, Shimano quality

I purchased the new TRP EVO12 cranks and this bb from Thunder Mountain. They promptly answered all of my many questions both before and after my purchase. And the cranks and bb are great. One of only a few 165mm carbon options out there. I also had lots of questions for TRP and they responded immediately and were extremely helpful.

the 50mm reach A318 gives the option of ~5mm rise or drop, the latter of which is perfect for my XC / downcountry style. happy to pay for a US-sourced & -made piece, especially when it's as functionally elegant as this stem.

Hey, just wanted to say, everyone there is awesome and the back team in the back were awesome. Answered all my questions and I finally got out the weeds. My AXS set up is the bomb and I love it in the woods where we live in Northern Fla. Destin, Fort Walton beach area. I'm a huge Surfer and have been all over the world surfing but, moving back home here is not a lot of surf so I found MTBing!! What a game changer. Its all I think about. Cant wait to start to travel a little to get better on trails and tracks. 61 strong today and ready for my next big venture. Thanks again team for all the support and advice. A loyal customer,

Awesome shoes, but the shipping and price were unbeatable. Thank you for an amazing experience Thunder Mountain. I'll be back :)

These brake pads are great. Long lasting using moderate pressure and great grip. Inspires more confidence in tackling the downhills.

Product arrived quickly and with no issues - customer service was very helpful.

Was able to get the right spindle width / specs were clearly shown on the product details page - 120 wide/55mm chain line - and got back out on the trail. Thank you!

I’m using it on the left side to control the RockShox Reverb AXS seat post. Perfect match.

Excellent product description, I knew I was purchasing the correct part for my bike.

Great service!

Product arrived in time and as described in secure shipping packaging.
