SIZING DOWN WHEN YOU GET A NEW BIKE


Lee – So I played around with the RAD calculator at the Lee Likes Bikes MTB School for my Pivot LES and proposed rocky Mountain Element. Both bikes on the small come out spot on for the RAD but the reach and rise are too short and tall respectively for the bikes compared to the calculations using the XC or Trail setting, so I end up with more of an Enduro setup.

The Rocky Mountain size guide has me on the end of small or beginning of medium and one of the Michigan shops I called recommends sizing up. However when I enter the dimensions for the M Element frame in the RideLogic™ bike calculator, the RAD gets too big. In the comment section you say the RAD is more important than reach/rise in terms of priority. Any additional thoughts?

Scott!

Thanks for reaching out, and for being a member of the Lee Likes Bikes MTB School.

The core tenant of the RideLogic™ Bike Setup Method is matching the distance between your bike’s bottom bracket and grips to the distance between your feet and hands. This is called the Rider Area Distance. Since I’m in charge, I call it the RAD.


Rider Area Distance (RAD).

The secondary measurement is Rider Area Angle in Degrees (RAAD). This is the angle of your RAD compared with level. RAAD tends to vary with the type of bike. Low RAAD for an XC race bike; high RAAD for a downhill bike.


Rider Area Angle in Degrees (RAAD).

In my experience, RAD is most important measurement by a mile. Any bike with a perfect RAD and a reasonable RAAD rides great.

If you go for the larger frame, the reach can be so long it’s hard to get a short enough RAD. If you can get the RAD correct, the RAAD will end up low, and you’ll end up with a bike with a long, “XC” feeling cockpit. For most riders this will not feel good, especially on fun terrain. In my work with lots of folks, almost everyone, no matter their riding style, prefers a higher RAAD like you find on an enduro bike.

Modern bikes are getting longer and longer. More specifically, their reaches (horizontal distance from bottom bracket to top of head tube) are getting longer. In many cases, the stacks (vertical distance from bottom bracket to head tube) are also getting higher. It’s very common that riders need to “size down.”

Everyone: Before you buy a bike, plug your numbers and your bike’s numbers into the RideLogic™ calculators. They are available, along with tons of great skills lessons, with a Lee Likes Bikes MTB School membership. You can use the same calculators, and the RideLogic™ on-bike test, to dial in your current bike.

My new medium 2017 Enduro, which is amazing, is 20mm longer than my medium Stumpy. While I got the Enduro’s RAD within a few millimeters of perfect, the cockpit is too long for me, and it’s giving me a hard time. If my shoulders were healthy it wouldn’t be such a big deal, but this is hurting me so much that I think I’m going to return the free bike and try to get a small.

I hope that helps,

Lee

WHAT HAPPENS WHEN YOU ADD FORK TRAVEL?


Warning: For serious MTB nerds.

Lately I’ve been doing a lot of RideLogic™ bike setup consultations for members of the Lee Likes Bikes MTB School.

The school has a simple method and detailed calculators to help you dial in your bike for your body and riding style. One service I offer members is a $49 consultation. You tell me what you’re trying to achieve, and I do the calculations for you. This is a great way to dial in your current bike or choose your next bike—with total confidence. A lot of people spend thousands of dollars on bikes that don’t fit them. Not cool!

To run the RideLogic™ calculations I need accurate head angle and frame reach/stack numbers. When people install longer-than-stock forks, those numbers change, so I have to do some pre-calculation calculations.

EXPANDING YOUR QUIVER FROM 2 TO 3 BIKES

Lee,

Here’s what I am thinking – would like your input as I am getting a new bike [Mikkel, a Specialized ambassador, has been riding a Stumpy 6Fattie for the past year].

Epic – for XC racing and long rides

Camber 29er – perfect for the Santa Monica trails

Enduro 29er (with a 6Fattie wheel set) – for bigger riding (mount Wilson and shredding)

I am thinking of getting rid of the stumpy in favor of the Enduro.

What do you think of having those three bikes?

Mikkel

CUSTOM FRAME AND SEAT TUBE ANGLE

Greetings Lee. I am in the process of having a custom hardtail frame built, I have some questions about fit, seat tube angle, pedaling efficiency & comfort. Seems like a lot of makers are going with shorter stays and steeper 74* seat tube angles to keep the rider weight centered. My Builder thinks that a true 73* seat tube angle will work fine with short stays. Of course I want to be sure about the geometry.

Wondering what your take is on the steeper seat angles paired with shorter stays – certainly for short rides they can keep the rider in a good spot, but does that come at price – less engagement of the glutes & lower back, and thus less ideal for longer days in the saddle, for example?

Thanks for any input.

1X DRIVETRAIN FOR BIKEPACKING?

I’m a fit 52 old on a 2007 3×9 26” Ibis Mojo planning to bikepack the Colorado Trail in July. The drivetrain has considerable wear, and probably needs to be replaced. Do I just stick with it or move to a more modern setup? I’m considering moving to 1X11, 30t front, 11-46 back. I know and don’t have issue with 50% HAB on this trail.

Any thoughts?

STRAIGHT SEATPOST VERSES SETBACK POST ON SPECIALIZED BIKES


Lee,

I noticed that you always run a straight seat on your Specialized bikes that come stock with setback posts. How does this affect your knee/pedal position and the size of bike that you choose? It seems to me that your knee would be pulled well over the front of the pedal (especially with shorter cranks) and you might choose a larger bike size because the cockpit is 3/4 inch shorter which is about 1 size. Am I wrong?

Thanks for your time,

Rob Linnenberger

SPECIALIZED FUSE INSTEAD OF A STUMPJUMPER HARDTAIL?


Hey lee

and thanks for your homepage and your enthusiastic cycling world :-)

I ride stumpjumper evo ht at the moment and are considering buying the fuse 6fattie pro but im having doubt about the wheels and tires and the weight.

I ride all kind flat gravel, singletrack, xc and trips with my kids in a troller so i need a bike for everything :-)

Do you think it will to heavy ?? And how does the fuse pro handling climbing ??

I live in a very small mtb country and the fuse is no where to found so i have to order it overseas in the United Kingdom.

Best regards Rasmus from denmark

Happy Trails !

PLUS TIRES FOR XC AND ENDURANCE RACING?

Lee,

How do +tires fit in for someone who does XC and endurance races? That is the rub for me, I participate in several XC and endurance races throughout the year.

AIR PRESSURE FOR 6FATTIE (27.5 PLUS) TIRES


This comment was posted on Two rides on a Specialized Fuse Expert 6Fattie

I rode the Stumpjumper 6Fattie and thought it was fun on the technical climbs, I loved the way it leveled the trail trash. As soon as I pointed it down a rocky technical descent I felt like I was sledding on a tractor inner tube. The bike was bouncing all over the trail, no precision with the undamped bounce from the tires. I literally bounced off my line at one point and almost ate it.

I had pressure set at 14F/15R and did not experiment with it. Who knows what pressure I really had as it seems all gauges read differently. Anyway I wonder how more pressure would have made things feel. I felt the tires folding in turns when pushing hard too.
