I Shift SRAM GX Eagle Review

I Shift SRAM, GX Eagle Review

SRAM’s GX Eagle drivetrain has been far and away the most popular option over the last couple seasons.

MotionIQ – the How of MTB Suspension Data Analytics

  OK, you read the “why” about mountain bike suspension data acquisition (if you didn’t check out BikeCo Pro Rider Cody Kelley, Joe Binatena and Rob Pryzkucki from Motion Instruments discuss it here) let’s now look at the “how” of the Motion Instruments MotionIQ system. Those who’ve read a lot of BikeCo’s content know I love formulas and data. Everything is just easier when you can minimize variables with facts. So suspension data acquisition would be right up my alley right? [...]

Suspension Testing with Cody Kelley and MotionIQ

  Prior to EWS Northstar BikeCo Pro Rider Cody Kelley and Joe Binatena had a chance to work with our friends from Motion Instruments, a Suspension Data Analytics company. We could write a thesis on it, but to keep it manageable we’re going to break it down into two semi-succinct parts… This section will cover some of the “why” then jump over to the “how”.   Why Data Acquisition   Hard data about suspension narrows the setup dialogue. “I think” or “I feel” turns into [...]

30 vs 32t Comparison – Drivetrain Review

30 vs 32t Comparison – from a slow climber… We get a lot of questions on chain ring options. So when my old cranks finally gave up the ghost, press-fit eventually gets sloppy and the creak / get loose often, I decided to go to a bigger ring. So here’s a 30 vs 32t comparison – from someone who’s never, never been a climber.  Keep reading – it’s more than a saga of pain and suffering… My last couple bikes were [...]

SB130 Mullet Geometry

Lot of questions on the new Mullet concept. Yeti has come out with the geometry for the SB140 as well as SB165 mullet conversions (check out our interactive geo comparison here) but I got a lot of inquires on the SB130 concept. So let’s look at the SB130 Mullet Geometry. My first instinct, having owned and SB130 since the launch, is that the BB dimension would be too low for most riding conditions. But I’m all for a quick look [...]

Alchemy Nine7Five Ride Review

Alchemy Nine7Five First Thoughts

BikeCo.com owner Joe Binatena is rocking a mullet. We went for a pedal to go through his Alchemy Nine7Five First thoughts. “Mullet” bikes are 29″ front and 27.5″ rear setups. If you’ve looked closely on this year’s EWS photos you’ve seen them under a wide range of riders. Let’s take a quick look at the concept. Business in the Front The math of the business. 29″ wheels have a smaller angle of attack over obstacles. 29s are more likely to roll over rather than [...]

7 23 19 Yeti SB165 T2 X01 Complete 1

Coil Spring Tuning Basics

With the launch of the new Yeti SB165 we’ve had a lot of questions. Here we go with some Coil Spring Tuning Basics. Coil Spring Tuning Basics Some very basic principals to start with here. Coil springs are rated by the weight that creates an inch of spring compression. So a 400lb spring requires 400lbs to compress the first inch and would take 800lbs to compress two inches. However, coil springs are not produced to “exact” standards. That is to say if [...]

7 15 19 Compression and Confidence

Confidence with Compression: Adjusting your fork

Confidence with Compression – sort of a vague title right? Am I gaining confidence on trail from compression? Am I confident adjusting my compression? Well, both. The abridged back story: I had a chance to move further south. BikeCo’s website has been growing at a rate that I can now work remotely mostly and come up to the shop a couple times a week. Anyhow – for the first time since I started bikes I’m consistently riding trails I don’t [...]

180 vs 203mm Rotors

Power, Modulation, Heat Capacity and Personality. Let’s look at some differences between 180 vs 203mm rotors (7″ and 8″). Power Increasing the radius of the rotor increases the brake’s leverage ratio. Using Magura HC rotos as an example we measure about 12.7mm of “usable” rotor / pad interface. Picking a point of reference halfway in the usable interface the we come up with a 180mm (7″) rotor at 83.65mm versus the 203mm (8″) at 95.15mm. The change in available leverage around 12%. This [...]
