How To Build The Ultimate Gravel Bike

My gear Amazon affiliate links:

Time to build up the Bossi Grit gravel bike with a mechanical Shimano GRX 810 1x groupset and a set of No.6 G45 gravel wheels! This setup is designed for adventure, performance, and all-road capability. In this video, I go through the full step-by-step bike build, covering everything from installing the drivetrain to getting the perfect gravel-ready setup. Stay tuned for the first ride review coming soon!

Great build and video. Anyone who has completed building a bike with fully internal routing and mechanical groupset is a senior bike mechanic😂 I almost put a bullet in my head doing it. But the clean finish justifies everything😂

Another fine build!! Last week was super nice out here in Canada but I threw my back and no riding!! I did some today but I'll be rocking the winter beater for a week or two... I did place my order for some fresh up goodies for the summer bike... Can't wait for that first ride!! Glad to see you getting into gravel!! I only got my cyclocross frame because it was cheap and it was my size... 2 years later I can report I put lots of road mileage and also lots of trail mileage on the bike... Loads of fun ahead!!

28:04 😂😂😂😂😂

Also at 24:52 the derailleur is RX820 as it is 12 speed, 810 is the previous 11 speed generation.

Awesome build! Ti is super sexy. I have two ti bikes meself

Hi Michael, very nice build per usual. A suggestion given you care about these things based on the work you’ve put into lighting: take your camera off autofocus.

It’s much better from a cinematic (and viewer) standpoint to let the objects moved towards the lens (FG) and BG go out of focus while the camera is focused on you. Naturally, if you want to switch focus to the build, well, you can do cutaways with closeups (CU’s) but also close the aperture to have a longer depth of field. However, nothing less than f/8 should be needed allowing you to keep the gain still reasonably low (clean video).

Nickle Anti-Seize Lubricant is best to use between titanium and aluminum alloy (also between carbon and aluminum alloy)

Wow this is truly a special built! Amazing components and this frame is truly breathtaking ❤️ please keep up the good work with this great content 😍

Holy bananas - seeing you struggle with that one-piece integrated handlbar makes me never want to do that ;) - So glad all my bikes are "conventionally" routed.

I was screaming as you pulled the guides out of the bar 🙂

My kind of bike.. a gravel 🤩 just bought myself a titanium gravel bike and I’m loving it forever! 😍

Schöner Aufbau! Das Kettenblatt ist abseits von den breiten Waldautobahnen vermutlich etwas ambitioniert, da braucht man schon die Beine von Matthieu van der Poel 😂 Insbesondere wenn es im Sommer ins sandige Brandenburg geht. Ein 40er oder 42 reicht eigentlich für alles und bietet mehr Möglichkeiten im Gelände.

guitar string loop into those holes will fish out those hoses/cables

It's a good idea to use carbon paste on your expander plug too. Nice build.

I have a Lynskey ti gravel bike and they recommend using copper based anti seize assembly lubricant. Love the content!

Very nice build I might one day move onto a titanium gravel bike, which I would only use for gravel. I have a specialized diverge with GRXDI2 one by. I think my bike is heavier than yours. It does feel heavy. Maybe it’s because of the battery since it’s an electronic group set. Everything else is carbon. Perhaps your mechanical GRX is lighter in grams than what I have. It also doesn’t help to have a heavy Shimano XT cassette in the rear, even though I live in flat Florida the extra grams probably adds weight in my bike anyway, but thanks for this build. Maybe one day in the future this year I can build up a lighter one and sell my bike

My Bossi gravel bike is the ultimate. I have external cabling in the headset. I can’t really see the advantages of concealed cabling on gravel. The Bossi titanium bottle cages I have are really cool and yet another indulgence ha ha. I really enjoyed your video and enjoy the bike, the Bossi Ti frames are incredibly good.

When building a fully integrated bike, I always pop one of the rubber seals off each of the headset bearings and pack them totally full of grease b4 refitting the seal. These bearings move very little in use so drag is not a factor, and hopefully the grease will prevent water ingress and therefore rust, for much longer than otherwise. Replacing those bearings is a real pain.

Good build.. but why not use a headset made for gravel with some sort of dampening or cushion.. like a redshift stem?

[bengt_axle]

Be sure to have the ends of the cable outer filed off so that it is perfectly square, before you put the ferrule on. If it is not square (flat) the shifting won't be as precise as it should be, especially with all those bends the cable has as a result of the internal cable routing. And clamp to the seat tube!!!

Always copper paste you will when it starts creaking great build

1. Your wheelset already uses carbon spokes
2. You already cheated with a small range cassette (because the wheel does not support MicroSpline)
3. You haven't mounted pedals
Not ultimate at all :(
