Canyon Factory Freeride Team Aced 2016

The Canyon Factory Freeride Team finished the season with a bang, bringing home gold with the 2016 FMB Factory Team World Championship Title.

Factory teams must register a minimum of 2 athletes. Each athlete can contribute a maximum of 3 results and the final team score is the total of the best six results. This year, Thomas Genon (BEL) and Tomas Lemoine (FRA) each secured top ranks at different FMB Events and showcased their top level riding as well as unified team spirit.

Thanks to top performances by Thomas Genon and Tomas Lemoine for their manufacturer, based in Koblenz, Germany, the team beat their competitors and can proudly celebrate their team efforts. In addition to Thomas and Tomas, the Canyon Factory Freeride Team 2016 lineup consisted of three other members, including Anton Thelander (SWE), Darren Berrecloth (CAN) and Peter Henke (GER).

Tomas Lemoine: “The fact that we won the FMB Factory Team Ranking, shows me once again that our team is perfect. Each and every one of us is so stoked to ride for such a sick brand like Canyon. Personally I just tried to do my best during every event and I feel the same vibes go for everyone in the team. We will continue to train and give our best.”

Thomas Genon: “I have known my teammates for a very long time and we are super stoked to ride together. Everyone did great this season and now we´re all going to spend the winter riding, training and improving the things that didn´t work out this season.”

Sports Director MTB at Canyon, Florian Goral: “Our athletes can choose from a range of bikes, which have been developed by the engineers, being as close as possible to the riders. When we created the team back in 2013, it was our intention to build the best bikes possible. We started from scratch and have been listening to all their needs right from the beginning. Winning contests is the logical proof of pure talent combined with excellent material.”

Congratulations to the Canyon Factory Freeride Team and good luck for the next season.

Wheel Size Facts Part 1-Dimensions, Weight and Strength

The boys over at Banshee Bikes sent this along today it is a good read on wheel size.

"You may have read certain online and printed marketing startegies which talk about wheelsize with a significant bias towards one size. The size they promote will always be either the only size that the source company produces, or the size that they want to push. Intentional marketing spiels are often very misleading and can skew the purchaser's judgement.

I feel it is my duty to set the record straight by writing a series of blog posts that kick off with this one, which addresses two key components of wheel size: weight and dimensions (and little bit of strength thrown in for good measure!). I plan to give unbiased information that you may find useful when deciding what size hoops you want your next purchase to be.

I can offer nonpartisan information (actual facts, rather than marketing blurb) as here at Banshee we offer all 3 mountain bike wheel sizes. We let the customer decide what they want rather than force it upon them, so have no reason to promote one over any other.

Every wheel size has its pros and cons, so picking the best wheelsize for you really comes down to personal preferance. The main things to consider when picking wheel size are your riding style, riding purpose (style or speed), the terrain you ride, and rider height, but there are also many other factors. I'll try my best to cover the main ones.

The following camparisons for this whole series are based on using Maxxis High Roller II 2.3" tires on each wheel size with same rim width for all sizes.

Any comparison I do will be relative to 650b wheels since they are the middle wheel size and so it makes the % change figures clear and consistant.

Dimensions: (Outer tire dimensions taken from official Maxxis 3D files)

Straight away this table is likely to cause some confusion... because as you can see, none of the rims or tires match up to their name sake. You can find out why this is the case by reading from a master of bike knowledge Sheldon Brown.

However, one point to notice is that while 650b is marketed as 27.5", it is only 1" larger diameter than 26", and 1.5" smaller than 29", so it is significantly closer to 26" than 29.  The 650b tire (often marketed as the 27.5") does not actually fall equally between the 26" and the 29" tires, so the characteristics of the 650b are far more similar to 26" than 29" wheels.


Weight:

Static weight

Obviously, tire and wheel build weights can vary significantly for all wheel sizes. So I'm sticking with 2.3" wide High roller II 3C/EXO/TR. For the wheels, I will use Stan's ZTR Flow EX wheels for each size.

Static weight (the weight of an unrotating wheel) is often emphasised by marketing teams. But it only really matters when you lift the bike on and off a rack or carry it on your back. However, static weight does have an effect on the...

Moment of Inertia

Moment of inertia is resistance to angular velocity change about an axis of rotation. Basically, the higher the moment of inertia of a wheel the harder it is to accelerate (and decelerate). This is far more significant than static weight when riding a bike.

Moment of inertia is related to both radius and mass, as Moment of Inertia (I) = Mass x Radius². A low moment of inertia results in a fast accelerating wheel (easy to start spinning). The flip side of this is that a high moment of inertia is harder to decelerate (harder to stop spinning), and so the wheel will carry the speed better once rolling if all other factors are equal.

The below table shows approximate moments of inertia by using the BSD as the effective rotational radius for all wheel sizes. 

What these numbers illustrate is that if you ride flowy trails that do not require lots of braking and accelerating back up to speed, then a larger wheel might be a better choice. However, if the trail demands regular braking and pedaling up to speed again then a smaller wheel might be better suited.

If using the same effective components, then as the wheel size increases the weight and inertia increase accordingly (as you would expect)... but because inertia increases at a rate that is proportional to the radius squared, it goes up more steeply than weight as the wheel size increases.

Strength:

A factor that is strangely often overlooked by marketing teams is that of the strength and stiffness of the wheel. I find this particularily strange as wheels cost a lot of money, and are subject to a lot of abuse, and personally the lifespan of a wheel is a significant factor to me when chosing what set to invest in.

If comparing like to like wheel builds (same rims, hubs etc), smaller wheels will always inherintly be stronger than larger wheels. This is due to wider gaps between spoke eyelets and poorer spoke triangulation etc. So strength to weight ratio is something that will always be won by smaller wheels.

It is however easy enough to compensate for this by getting stronger and stiffer wheels, but they do generally either weigh, or cost more. So something has to give.

It doesn't stop there....

Weight, dimensions and strength are obviously very important factors to take into account when considering what wheel size to choose. But... there are other factors too! And if this mini-blast of physics chat hasn't put you off too much, stay tuned for future blog posts about topics where bigger wheels have the advantage."
