That right there is why I build my own bikes up from frames and do all my own mechanics and wheel builds. Looks like even massively expensive bikes come slapped together from the manufacturer with poor attention to detail. In my experience they also tend to have no-to-minimal grease or other lubrication. My costs are just tools, my time is free so I can take the time to do it right.

I'm really impressed by your commitment to build quality, if I didn't do my own builds, I'd fly across the pond for my next bike. As for the integrated Quark power meters, from my own experience I've only had Shimano chainrings wear enough that I needed to replace them. All of my SRAM rings are still cranking, with regular chain replacements. For road use, I don't see the integration being an issue, but for CX, Gravel or MTB, I've had enough ring strikes going over logs and granite that I want my rings as cheap to replace as possible.

Amazing, a humble little bike shop that should be the envy of all. Your clientele are so lucky. After years of abusing my body ski racing, marathon running, even in the late 80's I bought a LeMond bike and moved to France to play on the bike. My knees finally fell apart. I am rehabbing a total knee replacement as we speak, and planning on hitting the mountain (40 minutes away here in Oregon) and doing a fair bit of road cycling (easier on my remaining non bionic knee) next fall. Your videos and your obvious attention to detail (along with a dose of the infamous 5 year old) have and are encouraging me to build my own bike (Look 765 optimum). A few years ago I transformed a old Raleigh Technium (repainted and all) into a single speed for college daughter. I wish I was in your neighborhood. Thanks heaps for the inspiration. Sorry if I rambled on...that's what us old folks do haha

I see these one piece BB inserts as problematic once you want to remove them again. My Mountainbike had an adapter from BB30 to BSA in it.

I’d be curious to see your take on one of BMC’s masterpiece frames if you ever get your hands on one.

[@9090Glenn]

I have a Specialised Tarmac SLR4 (with Shimano Ultegra which is not a great fit as it used PF press fit Adaptors that seemed to constantly squeak after 3-4 months use - so needed to be replaced often - to fit a Shimano 6750 Compact Ultegra crank to a OSBB Tarmac SL4 frameset we used a WMPF30OUT1 Wheels-Manufacturing PF30 To Outboard ABEC-3 Bearings 24mm - similar to the one-piece BB unit you are showing - the results have been exceptional - hate to say I can feel increased watt output but ... I can - it seems there was some frictional resistance in the older PF Adaptors with the Crank that increased as they wore out - perhaps it is psychological as well - hearing that squeak in your BB seems to sap your energy - this new all-in-one BB system has proved to be the correct way to tackle this problem - converting to SRAM was a better option but too costly

[@Mapdec]

Nice. The Wheels BB is 2 piece thread together, but it is a good in between option. It has worked for you. 👍

[@nellyx1x493]

Yes, I have the same frame as you and tried a couple of 30-24 step down adapter options that didn't work sufficiently- the correct tolerances between the two are seemingly impossible to achieve, when ideally the adapter should be a proper press-fit itself but for assembly practicality it has to be slip fit. Once the adapter gets a bit worn it wont prevent the crank from rocking or squeaking like a quacking duck. The solution you found is the best one.. I have similar good results from the praxisworks bb30-24 unit- the only problem comes when it's time to remove it, hammer time.... the Hambini converter is the ultimate. I noticed the better stiffness from the outward bearing too, which is daft from a super stiff frame hobbled by the too narrow bb30 (OSBB) stance...

[@mislevis]

I had same problem with my BMC and Hambini BB few years ago.

[@jochem1986]

The aero extensions come with a bare metal strip that can be used for fitting them at the correct location every time. They cause the extensions to be at a perfect distance repeatedly.

[@Mapdec]

Yes. But we just wrapped the tape to that point, because the bar is quite inconvenient.

[@maniastrat]

BMC inventory for size 51 is very difficult to find at local shops. When you finally find a shop that has it, they can't ship it.

[@stevenfinocchio2964]

I have an SLR01 Five that I put a Kogel BB in and less than a year later the bearings feel quite rough even though I rarely ride in bad weather, pretty sure it's due to the same issue you found with this frame. I remember it being quite difficult to press in and if I remember correctly the "frame guide" that came with the bearing drifts I bought from Kogel did not fit into the frame so I'm probably going to end up doing the same honing process in the spring. If I lived in the UK I would certainly have you work on my bike, thanks for a great video and the honest assessment.

[@Mapdec]

Oh wow. You ignored the tight fitting gage they provided. Eek. Did you get them back out the frame ok?

[@stevenfinocchio2964]

@@Mapdec I haven't tried to remove the bottom bracket yet but I replaced the bearings for a temporary fix, I'm sure it won't be easy to get out but Kogel gives you a waterproof grease for the install rather than a retaining compound it should be doable. I tried asking a few of my local bike shops if they would be willing to ream out the frame for me but so far nobody wants to do it. The honing process seems easy enough but may I ask what you used to wet the stones? Looks like soapy water but I don't want to assume anything.

[@timtaylor9590]

i always take out the inner seals of the bb bearings since they come with duel sides but the inside of the bearings isnt exposed to anything, then ill clean out the thick grease and replace it with oil. also no / light contact seals seem to do the job rather than contact seals. easy and free gains when spending so much time and money for a race bike. its massively more of an improvement than buying ceramic bearings and its free. as a reference, the drive side crank arm of my shimano crank pendulums 4-5 times when dropping it from the 12 oclock position, with both arms installed. compare that to some that dont even drop and you can feel the resistance on every pedal stroke, i believe that adds up to a substantial amount over time

[@samueltrumpy4433]

I just finished building up the exact same frameset and have to say, the bb area is really bad. I already built quite a few of direct chinese brands and have never had such a poor spinning crankset after installing. Maybe it is because I used the standard shimano bb? I had to push the crankset in pretty hard. Thinking about changing the bb already. Maybe to a threadfit? Would you have one to recon for that frame and shimano 24mm crank? Other then that, the frame is built really nicely, like you mentioned, perfect fork and nice guidance inside the frame for the brake hoses and everything. I built it with the ics fully integrated handlebar and that was actually a nightmare! Compared to a directly chinese fully integraded handlebar, that bmc branded thing which costs 5 times the price, it‘s actually embarrassing how bad of a build it is. I hope it at least rides perfect! Thanks for the video and the insights! Greetings from Switzerland.

[@Mapdec]

If you had to press the crankset in hard… stop, pull it back out, remove the BB and figure out why the cranks was hard to install. Often the compliance in Shimano BB hide a multitude of sins, but this sounds tight.

[@samueltrumpy4433]

@@Mapdec thank you very much for that quick answer. I actually could install everything and ust testrode it. It works perfectly, no creacking, nothing. So you still think I should get the bb out then? I didn‘t habe to hammer it in or so, just give a little bit of a hard knock with the hands..

[@graemehill]

With these non-circular steerer tubes that a lot of modern bikes have how exactly does the stem attach? Is it like D shaped seat posts where you don't have to get the seatpost alignment right because it only fits in a single orientation? I'm wondering whether there's a higher damage risk if you crash. With a normal stem/steerer it's common for the handlebars to go out of alignment in a crash but that's better than breaking the steerer or handlebar.

[@Mapdec]

There are semi circular inserts. The stem would still rotate around them.

[@graemehill]

@@Mapdec good to know thanks

[@neilk22]

Some rare skills there, not many bike shops with this type of time and attention to detail available. I wander if carbon frames and carbon epoxy are not susceptible to minor defects, it’s quite organic to plug prepreg into a mould vs alloy which is more of a mechanical science .

[@Mapdec]

Yes. Prepreg layup is quite an art. Done badly and you get voids or lots off additional material to compensate. RTM like Time and 3T uses is generally better to eliminate voids and give more creativity in the weave.

[@jasondurand4049]

Love your videos. Really informative. Do you know if the BMC 2-piece bar and stem can be used on other non-BMC frames?

[@Mapdec]

There might be a few with the cut out steerer tubes. Might need a lot of checking though. I doubt you would get all the fairings if the headset to line up

[@valmorell]

I like to see a little bit of play in head bearing seats. Without play, the bearing can be very slightly off centre which makes it next to impossible to get the head bearings to stay tight without overloading them

[@Mapdec]

There is more than enough for that.

[@galenkehler]

There are quite a few nice options in non-DuB cranks, you don't need to be held hostage by sram's choice if you want a better bearing

[@Mapdec]

[@galenkehler]

Sorry if this is duplicated, can't see the other comment: Rotor Aldhu makes a 24mm axle, and you can use a variety of power meters. I use the Power2Max spiders, with a 104bcd on my gravel bike (using a road Aldhu crank)

Good idea to fix the bottom bracket Yourself, because a new frame from the factory would most likely have the same problem. 👍

Beautiful Bike, thank you again for sharing this with us. I noticed how thin the material is around the BB, is this a common thing on high end race bikes? I love how beefy my Domane is around the T47, gives me lots of confidence its not likely to crakc/break where in my mind all the stress is?

[@diehardbikes]

Personally in regards to the power meters: i think that if they made the power meter removable that would be a great upgrade. If they used a torx bolt system that might be they way to go. Or maybe a chinch system. Just some ideas. It is true that if you dont tighten them properly readings will be off, but its just the same as the chainrings tightened to the arm, in that case. So no real difference.

[@ChlorophyllCrusher]

Am I right in thinking brands allocate their best (wrt QC) frames to frame-only sales, and the rest to become completes? I’ve suspected this for a long time…. If common practice, in fact, might we surmise that companies that are not selling frame-only don’t do good enough QC to pull it off?

just a quick fyi from a local bike shop mechanic, i agree barely any bike shop would go this far with a bike build simply because we dont have the time to spend an entire day on one bike, through any day we're maybe tuning up some 15-20 bikes as a small shop and all of these bikes are basically apollo/carrera bike shaped objects that people cannot simply afford to replace. i fully understand a boutique shop selling only £4000 to £14,000 frame builds should be doing this wih every bike but your average bike shop selling family bikes simply do not have the time or the staff to be spending a full day completely stripping a new bike down and rebuilding it as a part of the PDI process its simply not economical or profitable on bikes that sell to 98% of the market which are well under the £1000 mark.

[@Mapdec]

Aye. Those bikes don’t really need it. For years Park Tool etc have made quick easy tools for that use. I assume you have a frame alignment gage, hanger alignment gage, dropout gage and a some frame taps and tools to hand if you need them.

[@brendangormley-e3x]

I know you’ve done this video over a yr ago and I’m only watching it now. But one question for you. The fit for the bottom bracket is perfect after reaming and you aligned it by using 400 grit sand paper. But how do you know when you assemble the bottom bracket that it’s actually sitting square through the frame. The fit can be good and the two holes either side of the frame aligned but it could still be off square?

[@Mapdec]

Keep watching the channel. There are plenty to get into. We use a combo of parallels, a jig we have made and the park tool reaming tool. We also discuss bearing clearances and retain compound to set alignment. Happy viewing

Curious as to why you chose wired blips on the extensions rather than wireless blips? Mounting can be an issue but SRAM have a made available for free download STLs of different mounting adapters to easily 3D print these.

[@Mapdec]

Less batteries. Preferred ergonomics.

[@dogukantosun5547]

Hey Mapdec, what is the best spinning BB standard in your opinion?

[@sabamacx]

Even the cheapest $10 Shimano BB's spin beautifully provided the frame is manufactured and prepared correctly.

[@Mapdec]

BB standard for best spin??? Probably BB65. Let’s not go there. With enough accuracy a Shimano Ultegra BB will spin perfectly well. Lots of track cyclists still use octolink etc too.

[@JibbaJabber]

BMC - r u watching?? Everyone else - you've been warned!

[@Onigure]

I'm still amazed a 46t chainring exists, even use it for racing. I have much to learn about gearing.

[@Mapdec]

Remember there is a little 10t back there.

[@galenkehler]

As Mapdec says, with the inclusion of the 10t cog they're expecting you to go smaller in the front. Multiply the front by 10% to get the rough equivalent, so a 46t will ride roughly equivalent to a 50-51t on a traditional cassette (11-xx)

[@Glebaka]

@@galenkehler i dont think that any of pros keen on using 10t cog as its not efficient

[@galenkehler]

@@Glebaka 1. You're absolutely right and the 10t sucks. 2. In the video, it was stated that the user was both low power and low weight, so inefficiency will be a pretty small consideration, especially if they're looking for lower gears they probably won't even use the 10 or 11 tooth cogs, and certainly not in a high power situation. 3. I totally agree with you, and I don't think I'd ever run a 10t cog, I dont even like 11

[@nellyx1x493]

10tooth cog has no place on a road bike. Have it on the mtb, and you can feel through the pedals that it shouldn't be trusted - it's ok for mtb, but wouldn't want to be putting the meat down through the pedals on road in that gear. Ok for bimbling though I suppose. Bigger chainrings give a noticeably smoother pedal feel anyway, something you notice going from standard to compact, so why anyone would want to go even smaller is beyond me. What this is, is brands having to reinvent the wheel every so often to stay relevant.

[@okantichrist]

So when your chainrings wear out that’s your power meter in the bin as well??

[@Mapdec]

Yes. However these are not your cheesy Shimano or FSA rings. They are considerably more durable. It’s not perfect, but there are lots of pros and cons to the argument, about as many as every other powermeter. I’m going to have to do a vid I think.

[@bigwave_dave8468]

Brilliant work. It seems very poor of BMC to sell such an exotic bike and not check fundamental things (bb and rear cassette operation) Note to self...oh, nevermind, I wasn't going to buy it anyway :-)

[@docmccoy9813]

I''m definitely going to buy a titanium frame in the future. You can''t even trust a 4.000 pounds carbon frame!

[@Mapdec]

Don’t assume that it will be perfect because it’s Ti. It’s a really hard material to weld. Few do it well.

[@docmccoy9813]

@@Mapdec I'm sure if it's near that prize tag, that frame would outlive me, if there's no crash involved.

[@Mapdec]

Did you see the Zinn vid?

[@docmccoy9813]

@@Mapdec No. Watching it right now. Thanks!

[@harleypurcell7766]

Tyre logos not lined up with the valves… whats going on?? 😂

[@janeblogs324]

You don't epoxy the bare carbon that's exposed after honing? I get that its a race bike, but water drips down the seat post and enters into the pressfit BB interface and it will fray the carbon. I'm sure most manufacturers just hone already cured carbon which is why creaking sets in eventually

[@Mapdec]

Lol. The carbon was bare before honing. There is no clear coat or anything down there. Never is. The resin impregnates at every level if anything frays it’s because there are voids. Water shouldn’t be able to enter any part. It should be a solid of carbon and resin. Made well you can machine, cut and grind carbon. Steerer tubes are a good example. So much fear and misunderstanding arround Carbon. No wonder mechanics are afraid to touch it and let undersized junk out onto the unsuspecting public.

[@richardhaselwood9478]

Meanwhile, my $1800 Australian, 2018 Giant Fathom, passed the crank spin test quite nicely (Shimano PF BB, so, 24mm axle). Gah..... This is why I'm not tempted by BMC.... Sticking to Giant and Merida bikes. Excellent warranty, easy to get replacements. Excellent QA (generally). But, otherwise, what a build :)

[@feedbackzaloop]

The best way to deal with Sram DUB is to avoid Sram DUB.

[@_Zane__]

Hah, is sram that bad?

[@feedbackzaloop]

@@_Zane__ not _that_ bad, but it's just nothing you can do about it.

[@Mapdec]

But then… Shimano Power meter 🫣

[@feedbackzaloop]

@@Mapdec there are plenty of other powermeters for Shimano axle... At the worst Sram still has GXP, if you want to remain true to the brand. As you shown, 30mm axles are no good fit for 41mm bores

[@justinharrington6335]

Worst thing about sram is when u need to maintain it. Badly designed and crap. Used force and rival 1x.

[@gregoxenham2842]

Good vid.

[@Mapdec]

Thank you.

[@rodcosta2345]

Either that's the smallest 51 ever or you're related to Sasquatch... which is it?

[@Mapdec]

It’s a 51cm

[@mohamadkhanafer7978]

Should I be worried regarding the bottom bracket? What would be a good solution, I’d like this bike to last as long as possible

[@Mapdec]

The solution is just to check it and fix it if you need.

[@mohamadkhanafer7978]

@@Mapdec how often does a press fit bottom bracket need to be changed? I put in about 2000 miles a year. And how do I maintain it if there’s any maintenance at all

[@seanmccuen6970]

merely attends to the common pragmatic details of a build from A-Z, then calls it 'gucci'. lolol, more power to ya.

[@NeoPayneHK]

so if you want a perfect dream build one of the option is just go to MCW and talk with them right?
