Thank you! 🙏 Do stick around then, there is a lot more of them coming! 😉

Awesome build, looks mean!!! I have a thing for quill stems and higher handlebars but that’s just me. Super cool part selection and silver was a great choice. Subscribed!

Great job, hope to build a similar bike me too. I’m a novice to the bike world and i noticed that you use two different grease, could you explain to me why and which types are they? Thanks

[@bottoncino_bicycles]

Hey, thank you! Sure: One grease is used as an anti-seize, so it basically prevents two metals from rusting onto each other. The other is a lubricant that reduces friction and ensures that bearings run smoothly

[@anders8707]

Beautiful build! What model is that ahead stem adaptor?

[@bottoncino_bicycles]

Thank you! It is made by PRO. If you are located in the EU, you can order it through us, if you cannot find it elsewhere.

[@oreocarlton3343]

Georgeous groupset, why have you switched to copper antisieze instead of the regular grease?

[@bottoncino_bicycles]

Agreed! Been using that for a while actually. Just looked so rusty in that shot that I thought I'd point it out

[@oreocarlton3343]

@@bottoncino_bicycles is there a reason why you prefer copper grease? Lot of rain?

[@bottoncino_bicycles]

The Copper Compound has a very nice consistency and is easy to apply

[@sethdevine365]

What was that spacer you used with that quill stem adapter to fit the stem? I have an old Gary Fisher bike with a wider than usual stem and I’m looking for something like that so I can use a different stem set up. Thanks in advance! 3:49

[@bottoncino_bicycles]

It's a pretty nifty quil stem adapter that is at its core 1" to 1", but comes with additional shims to fit a 1 1/8" fork or stem. Are you located in the EU? If so, you could purchase it through our shop

[@muhammadraihansyah8557]

Is it work the road bike brifter with mtb rear derailleur? I have a vintage shimano deore xt rd and want to use a dropbar for my mtb

[@bottoncino_bicycles]

Yes, rear is not a problem, but front derailleur setup is more challenging

Petit tips pour le capot de potence qui fait un peu cheap sur un velo aussi bien fini, moi j'ai percé un capot de potence aheadset un peu plus gros et avec une vis plus grande on peut visser l'adaptateur 1" comme un aheadset ;)

[@bottoncino_bicycles]

You are right, a silver top cap would have been even nicer 👍

[@summitcrafted25]

14:10 I am pretty sure you put the headset bearings in the wrong way. The balls should ride in the cup and the cone rides on the balls past the cage.

[@bottoncino_bicycles]

Don't worry, they're in the right side up and the headset runs smooth
