Yes its time to bust the hype around "Marginal Gains". Here are our Top 10 myths surround David Brailsford's Marginal Gains claims which have reportedly powered British Cycling and Team Sky to countless victories!
For the record we are not claiming marginal gains do not exist, we are claiming they don't work as advertised / as commonly believed. We are busting 10 common misconceptions of marginal gains. Tell us if you agree or disagree?
Here is a big countdown of all the top aero savings you can make on the bike according to science (wind tunnel). Specialized tested 88 aero settings and we summarize the 35 which are no cost options. Of these 17 can be stacked together. Method: In order to convert seconds over 40km we assumed an 80kg rider at 40kph and 300w baseline watts (200w on hybrid) and converted seconds to CDA to watts using cyclingpowerlab / analytic cycling. Ps. in the countdown there are 34 savings but we added one (clothing size) at the last minute making 35. 
CeramicSpeed is under the microscope! Here we address the our view on Ceramic Bearings and in particular the CeramicSpeed OPWS (Oversize Pulley Wheel System). Does it save "at least 2.4w" for *only* $449? Remember Watts savings are never guaranteed! Note that all opinions in the video are based on FFT personal opinions and of interpretation of data in the public domain and of our new XLS estimator. These are our truthful opinions on the products listed based on our experience . We have no malice or disrespect for CeramicSpeed and genuinely wish them every success in the future.
For "FTP" (often thought of as 60min best power) it is said you should take 5% off your 20min power. This is important as it is used to define training zones. If the calculation of FTP60 is incorrect, power based training zones may be off. Since then thousands of cyclists have uploaded data and it turns out this is probably the biggest myth in the field of training. Despite almost every website and book propagating this 95%/5% rule modern analysis shows this is incorrect for a large number of riders. Remember prediction is not always 100% accurate but we think we can do much better than the 95% rule. 
Here we will help you find the the fastest tyre/tire for TT road and Triathlon and in doing so save you about 27-39 watts (depending on rider weight and speed). Others have tried but FFT now presents the definitive review. Using Tom Anhalts amazing database which we have improved and refined. This is a countdown of the best clinchers tyres and an associated spreadsheet too to make finding the perfect tyre easy.
We examine how riders can save 74 watts of losses by paying attention to the hidden and mysterious science of bicycle tyre (aka bike tire)! In all truth only a handful of people fully understand this area which has been intensely studied in wind tunnels and labs over the last 10 years. If you doubt you could save 74w try putting a old worn narrow almost flat tyre on your front wheel and tell us how you get on! [most tests carried out at 40kph] Savings are: 10+13+27+20+5+3+6=84w but I took off that first 10w and it is mutually exclusive with the 13w. 
Here we examine how some riders can save up to 30 or more watts in drivetrain losses by paying attention to their chain alone (and going from a very lossy to optimised chain). In truth you can only "limit losses" and never truely gain watts because every bike loses watts / power in the mechanical parts. If you made all these mistakes we estimate it could cost you 34w. However by paying attention to these 8 steps you could turn -34watts into only -4 watts of losses (saving a potential 30w for a strong rider with baseline 400w) 
Do Q-rings improve power? Here is our answer, focusing on scientific facts and evidence not speculation. Yes here at FFT we have used q-rings & osymmetric for over a year. However absolute proof they help is not clear. Here we talk about the basics of the effect of non-round (oval) rings on power, torque, pedal speed, bike speed. Firstly from a lab perspective where we can test one leg at a time, then in the field two legs. Thus we address: what exactly is the "dead spot" in the pedaling motion? In the lab it is the effort the carry the leg back up to the 12oclock position, in the field it is the transition between the dominant down strokes.  

Here is a very common problem. You have an older 10 speed wheel and want it to work without your new 11speed bike / gearing. Here we run through the 7 ways you can make the conversion for almost any wheel. Also don't overlook all those 10 speed wheels sold second hand at rock bottom price because people want the 11sp version. If you have a short attention span and want a quick answer go to 12:44

Here we discuss how to pace climbs correctly, how to attack long climbs and short hills, how to chose the correct uphill position (sitting vs standing) and how to chose the correct equipment (climbing vs aero wheels). We discuss optimal position, optimal equipment, optimal power, optimal pacing.
Crank Length is important but usually totally ignored. Very rarely do cyclists change their cranks or even pay attention to the length. Here we discuss the science of crank length especially how it effects cyclists' power (torque) and pedal speed (cadence). Why stick with standard cranks of 172.5mm (on a medium fit bike)? GCN found a 2% improvement in expired gasses and a big 20% improvement in blood lactate going to 177.5mm from 172.5mm for a tall rider (4.6 vs 3.7). They also found 12% inc in sprint power with long vs short cranks (984w vs 848w). Watch this video for the science of crank length.
