you're right, but there's economical reasons for them not being compatible I believe, this video is gold tho

Love this comment. Im planning on hacking the left one to operate the dropper post, its gonna be awesome!

Bike shops can be really pretentious sometimes

Exactly my thoughts, I have the Breezer Radar that cones stock with this mullet set up! 9 speed Shimano goodness ❤️

I have the same Sora brifters with XT shadow 9 speed mech and 11-34 which works perfectly. I also have an SLx crank with 44 outer and 36 mid (sometimes a 32) all through a Sram 2x10 front mech and the left had Sora 2x brifter. I am super fussy about gear slickness and the whole setup works smoothly and quietly. The only thing I should make clear is I set the chainline up so the front mid ring would cover all 9 on the rear whilst the outer gives me a sort of 'overdrive' for the road etc with the upper half of the rear cassette.

Afaik, Shimano 9s road and 9s Mtb is compatible with each other. 10s and 11s are not.

Thanks so much for the super thanks Aidan! Really appreciate it!

Ill sort them out when I get home. Shot mate!

Files are up!

I've had good luck with Gevenalle on many bikes using XT and XTR 12 speed drivetrains.

Those hand gymnastics tho

Брат, какие параметры выставил? И какие грх с деором?

@@koshkofleshka к сожалению нет этой инфы( замерил сейчас, большой ролик 23мм а малый 16,5мм. Честно не помню как я их вычислил и как их туда вбил)))

@@sergeybutko7982 ладно, спасибо. Дождусь свой грх, буду разбираться

you can use Alivio and Deore (old 9v ones) with 10v road Brifters , paired with a 10v cassete, these rear mechs can shift 10v . I just build my 2x10 using this and yeah, its a pretty nice option

From what I read the front MTB derailleurs are not compatible with road shifters even in the 7 8 and 9 speed systems. Does your experience prove otherwise?

@@klausdunayev7078 I'd have to refresh my memory to get the details absolutely correct. My recollection is that Shimano rear derailleurs and shifters are compatible between road and mountain bike components except for the very high gear counts above 9. The front deraileurs and shifters are not compatilble, i.e you cannot mix and match a front mtb derailleur with road shifter. So to covert an old mountain bike to drop bar you can get a set of road shifters and new front derailleur. Possibly a new crank set as well. I'd have to double check that. I haven't actually done my old mountain bike yet, but I plan to and that is the rough plan. Subject to a final confirmation before I order parts. I know one thing for certain: I don't value 1x drive trains over 2x or 3x so I won't go out of way to convert to 1x. But that's a personal preference.

Haha cheers. Think I need to bring the beard back.

@@juliangoulding And after watching this video, this 3D print component is really impressive and creative , shimano will hate you if they know this. You finished a thing, which the other players dreamed for years.

Yeah i didnt see the jtek when doing my research for this one. Looks like a great product. Crazy how similar my design looks to it haha

You can find the ratios here: blog.artscyclery.com/science-behind-the-magic/science-behind-the-magic-drivetrain-compatibility/ In my bike I had an 8 speed Shimano shifter (4.8 mm sprocket pitch / 2.8 mm cable pull = 1.714) and a 9 speed SRAM derraileur (4.35 mm sprocket pitch / 4.0 mm cable pull = 1.085). So 1.714/1.085 = 1.58 is the diameter ratio.

Great link that. I hadn't seen that jtek shiftmate, crazy how similar it is to the one I made 😂

@@umcaranumacaloi1062 and how I must change which Parameter for shimano 10road to shimano 10speed mtb

IIRC 7, 8, 9 speed MTB and 7, 8, 9, 10 speed road have the same pull ratios at the rear, so that should all be compatible, but road and mtb have different front derailleur pull ratios, so that'll be a problem. but i'll need someone that is more knowledgeable than me to confirm this info. of course none of this is impossible to circumvent as shown in the video, or you could also modify a front derailleur to change it's pull ratio, if you search about that you'll find people that have done it. so basically you should be able to make it work, just that not easily lol

10 speed

Yeah should be fine

Shimano 10speed road brifters are compatible with all Shimano 9speed derailleurs. Had 2 bikes with set-up like this. Perfect shifting

@@pluszkin I had s bike too and it not shift perfect in some gears

So is that is you dont have both shifters? I have the second shifter that Im replacing so i used that. Have a look at that like in the discription, you mint find you derailuer there. Finding it with just the derail

@@juliangoulding So i measure shifter pull and derailleur pull (from website) and input in Fusion 360 file. For your example Shimano 105 10sp is 2,3mm pull x 10= 23mm and you measure 32,5mm for deailleur. Right? Sorry for bothering you

@@zoranbjelotomic4806 yes that is correct. No worries.

Sensah ignite are road and the same pull like sora which is road too. Both are 9 speed and should work without a mullet

Going great. We've been open and running. Heaps of people coming through amd loving it!

dont get me started on the minefield that is bottom brackets lmao

They're the same under nine speeds for Shimano and I think SRAM too. It's only an issue for the big 1x systems.

Can't quite remember but it was a BBB one, half carbon half alloy.

Or just buy the options that are already available?

@@Bungle2010 Because sometimes what is available isn't what someone wants.

@@EricPeelMusic Except there are already gizmos available that do exactly this. This video is the literal definition of reinventing the wheel.

@@Bungle2010 No. There are solutions available for a limited number of shifter/mech combos. This video assists in obtaining a solution for combos not yet accounted for
