Specialized Tarmac SL8 vs. BMC TeamMachine R *Clash Of Titans*

[@GCPerformance18]

First of all I need to give credit to my friend Danny his Instagram is instagram.com/dannyswellchasers/ I would not be able to product this kind of product without him, if you are looking for any kind of professional production. dm him, his video skills and editing skills are top notch!!! Now for this video, This video I had so much fun filming and mainly I filmed this just because the stars lined up and had 2 top tier demo bikes in my store at the same time and was able to have some fun on top tier bikes. I wanted to make a visually cool video that was enjoyable content, the results at the end I would love to know your feedback on the case because there was a clear winner on paper, but is that really the truth. Please let me know if you want me to continue doing more videos like this in the future :). Thank you to everyone who is always around always messaging me and emailing me. I just like to have fun on bikes and ride in some beautiful weather

[@liquidSpin]

bruh, I was just about to say wind could have been a factor. Sometimes winds may me moving in the same direction but there are times when the wind dies down a little or you might get a few small gusts here and there. If you had all the time in the world it would be nice to test each bike 3x each and take the average of both to compare. Great video regardless~ I'd still take the BMC over the SL8 tho haha

it is what it is, Im one guy trying to control the elements, the winds were a tailwind and guests were up to 16mph that day, people perform speed tests in wind tunnels and say that data is not real because of cross winds and other elements and then when people are on the bike in the real world people ocmplain they need more control, I controlled everything I possibly could and stayed within 1 watt on my computer with the equipment I had to deal with

[@GCPerformance18]

it was pushing both but I do not know by how much

[@Oakpathetics]

From living in a windy area I know it doesn’t take much of a difference in wind speed/direction to have a massive difference in bike speed.. you need to do the test again and: Pick a non-windy day Do a circuit (not a straight road) Do two rides on each bike and take the average

[@chris_gb_]

I don't think you need apologise for any deficiencies in the test, it's pretty good, and if you want to do more of them this is a learning experience. 1W difference between runs is on par or better than some of the GCN efforts, and they're ex pros! You can't do anything about the wind, but maybe you can use a gadget to log the wind changes between runs and estimate the effect? Does Peak Torque so something like that? Traffic is a PITA and those vehicle blocking the lane could easily account for unexpected time differences. All I can suggest there is go out at 4:30am - 5:00am before the traffic builds up, but I think everyone understands that's not necessarily possible with family and job commitments. Power meter pedals swapped between bikes would be useful, run them in parallel with the Quarq meters you would see the difference, it probably won't be much though. Probably the toughest challenge is getting the bike setups identical, and holding an identical body position for the duration of the run. Slight changes in you body will affect the result quite a bit, but you're not Dan Bigham and you don't have access to a wind tunnel, so I wouldn't worry about being perfectly optimised. Maybe one of those phone apps could help? What matters is being consistent, but if that sucks the fun out of it then just don't worry about it. Most important thing is just to enjoy it, and just share your thoughts on the experience of each bike. Anyone complaining the test isn't perfect is in the wrong place.

[@GCPerformance18]

yea they are so nice

[@derekt3923]

The video is great content, very nice to see your opinions and facts about the bikes. As far as the science it’s not accurate, not because the power meter, but because in south Florida the wind is never flat or perfectly from the side; perhaps if you did 2.5 miles each way it would be closer. But again, your opinion and description of the bikes is very good content.

[@GCPerformance18]

yea I know I think the wind did pick up a little more, it was tought I tried to control as much as I could but it didnt work out the best

[@horsepastedelish]

You have to repeat the test many times and average it out to come to an accurate conclusion. You would also have to alternate the order as winds pick up from morning to late afternoon more times than not (especially around the east coast). As little as 1 mph of tailwind/headwind can explain the difference.

[@GCPerformance18]

I agree with that

[@rg807]

Production quality is way up! Nice work.

[@GCPerformance18]

Glad you think so!

[@rg807]

BTW, I used to live there, and rode A1A all the time. The wind.. if you know, you know. The difference in the result could simply be because the wind, as you know, is stronger later in the afternoon.

I really don't get why they're putting 42cm bars on an S-Works. A bike that's meant to be raced and they're speccing an endurance/gravel cockpit.

This is a fun video, something different from the usual. Wouldn't stress about the exact power. It's not a closed course. More important is all the personal preferences about which one you like better. Even handlebars or saddle. Once you're at this price point, swinging a bit extra for components you like is no big deal

[@mmfong297]

Cool foortage! Is this recorded from a drone or someone with a motor bike? In terms of the test, yes it's uncontrolled environment + diff pwr meter. I think it would have been better if you do a back and forth route. I am not surprised SL8 is gonna be faster than that BMC, but the 1mph avg speed is quite massive. In a race, that's almost like between 1st and last place

Hey GC Performance, Great Test 👏🏻 I’m SL8 fanboy so I’m happy with your results haha the only difference that I can see is one bike ascent 37ft and the other 30ft. Could be that 1w and 7ft elevation the 24” differences between these 2 bikes? Idk we’ll be waiting for your next test

[@GCPerformance18]

I have no idea why the elevation was different, ti was the exact same course, so unless the hammerhead gps that was recording the data is off and had a spike, because i did not have a speed sensor on there, but also I ride the same group rides and same routes over 30 miles and some how my elevation is always different

[@morrisizing]

Tough to do these comparisons given the variables it needs more runs to try to average them out. Obviously the wind, but also how you sit on the bike, slight fit changes - saddle height etc, being warmed up & a bit looser vs earlier on in a ride, riding over slightly different parts of the road, tyre differences if tge wheels aren't swapped, any change from vehicles or parked cars you pass etc etc. The powermeter differences can be reasonably large all mine measure differently. Even using an aerosensor to help you need to be strict on your testing protocol.

[@GCPerformance18]

yea I know I was trying to get a test data for real world use, those roads I ride everyday up and down so I want to see how the numbers perform on that road

[@christhornham]

Your position is one of the biggest factors in this test. There could be a significant difference if your stack and reach values vary. I’d say the variance in these result has more to do with your position and wind changes rather than the bikes.

[@GCPerformance18]

Yea I tried to stay in the hoods the whole time and both bikes had same stem length and also lowered the exact same. The only thing was bmc had the 36 bars. But that’s there own winning formula. I tried my best to stay true to

An exaggerated performance difference in this "TT-test", although the 2 different power meters reported only 1 watt, a negligible value even over such a short distance.

[@fabianmolyneux2308]

I suspect the gearing being different on each bike may have created a difference too. I agree narrower handlebars are way more comfortable. I am bias to the SL8 myself. Great Vid

[@RyonBeachner]

Gearing shouldn’t change anything when power is controlled. Power (Watts) = Torque (Pedal Force) x RPM (Cadence)/9.55 You can put out 220 watts with higher torque, and lower cadence, but also with higher cadence, and lower torque. Given the drivetrain losses should be identical, 220w should be good for x speed provided all other conditions are the same.

[@BikesKomsCRO]

This is good.. However you should run that test with the same exact tyre/width. And maybe run 2 or 3 times for avg time and then up the wattage and do it again and get an avg. Weight does not matter much on flats. You couldve encountered some more winds and that's the only reason sl8 could be faster.

The BMC did have the narrower handlebar. Agree a bit shocking. You could repeat the test by swapping wheelsets and/or handlebar. Devil is in the details, but I know one thing for sure having ridden today in Florida in the wind on my 2012 Roubaix SL3 with mechanical Rival and Campy alloy wheels which weighs 17 lbs, at 70 y.o., I could have held your wheel for that test. 🙂 Thanks for the content. PS. I am your height but lighter. Your position on the bike looks good and appreciate your videos even though I am old school relative to tech. FWIW I do ride a narrow handlebar and 165mm cranks which is new school as I subscribe to the benefit of both having ridden all configurations for decades.

of course I was mainly just doing this video for fun

1w is not even .5 mph You in in the slop of the measurement .. the bikes are very even . The differences likely due to wind and traffic 1 mph with all thing equal is gonna require ~20w … so data is fishy but thanks for trying 😮 and no way SL8 is 20w faster then BMC

[@GCPerformance18]

thank you for that

[@ilgour]

Too big of a difference over just 5 miles like you mention, power meter pedal is a good idea to control 1 more variable.

[@GCPerformance18]

yea I wish for sure I did the pedals I regret it so bad

[@sasha371]

you ride by cars, that would have massive affect on result. Cars passing by are pulling you along

[@GCPerformance18]

yea I am trying to give us real world experiences, majority of everyone who buys bikes will be riding in a bike lane along side cars

[@timtaylor9590]

7ft difference in vert. but i would guess the cars driving by made the most difference.

[@GCPerformance18]

yea I do not know why to be honest, I started and stopped the computer at the exact same spot it must be something with my head unit

Would be super happy with either as long as it had Dura-Ace instead of SRAM 🤣

[@GCPerformance18]

those sram hoods are a nightmare after I have been riding shimano for so long

Try telling Durianrider all this,he said the sl8 is the heaviest slowest worst bike he has ever ridden,he even recons he cracked the frame within a week!

[@dominicbritt]

Durianrider rides a bamboo bike… what’s your point?

[@davemellor4697]

@@dominicbritt The point is,is that he bought an SL8 and said its just rubbish,yet every person who has ridden this bike says its really impressive! And no he rides a bamboo bike for a stunt,he has has a dozen 2005-2009 older bikes with no electric group sets,rim brakes and flat peddles...SO my point is hes a fraud,or do you not get that?

[@petersouthernboy6327]

@@davemellor4697Durianrider does not own an SL8. He rides an older worn out bike and lives like the vegan hobo he is.

No one cares about that guy, get over it.
