Finding a Bike for the Butte 100

This may be the best part of signing up for a new race….  Getting and shopping for new gear.  Since I do not own a bike with any shocks, it might be time to get one.


Technology has changed so much over the past five to ten years, I feel like I am starting at the beginning of the learning curve. Here are my notes as I figure out the best bike for me for the Butte 100.

Hardtail or Full Suspension

Initially I was thinking a hardtail, but the more I researched and learned about the Butte 100 and taking on 100 miles on a mountain bike, it seemed it is in my best interest to make it a little easier on my body and go with a full suspension.


Please let me know your thoughts on any of the bikes and what works well for riding 100 miles with over 16,000 feet of climbing.

 Here is a thread at MTBR forums I started



Since the bike store closest to my house is a trek dealer, this was the first shop that I was able to see any in person.

They reccomended a Trek Fuel EX 8.  

This bike looked pretty awesome and seemed to be a fantastic value for the money.

This company has a long and rich history in mountain biking and I think it would make a good documentary, if one does not already exist.

After looking at their range of bikes the Yeti SB4.5C is probably the best bike for the Butte 100. It is a full suspension with a shorter travel. The reviews, posts and people I spoke with have nothing but good things to say about the SB4.5C.

Stock Build Options

Essentiall the bike has two frame options  Carbon and Better Carbon.  The better carbon is actually called the Turq frame. I think when it is all said and done the TURQ option is about 1 pound lighter, but is not all just about the 1 pound.  You get more carbon, like a carbon handlebar, and other higher end components.


TURQ (better carbon)

The TURQ also has a carbon wheelset upgrade option.  For $1,300, you can go from “DT SWISS 350W/XM421 RIM” to  “DT SWISS XRC 1200 25MM”
