46 steers noticeably differently than 42, and having fewer castings stops the price climbing too far. So much cheaper & easier to adjust offset with crowns.

As a normal person, I would disagree. Had a 51 on my Kona Process and it felt like a chopper. Had to start turning much earlier than I do with my 42mm offset fork currently on the bike.

I can’t say I agree with mineral oil brakes being in better shape after 7-10 years. Most mineral oil brakes I see being Shimano are a leaking mess and not rebuildable Sram and Hayes are. All O-rings fail after some amount of time it’s nice to rebuild instead of having throwaway items. Og Hayes still bleed and work the same kind of great at the time they did 20ys ago. I’m happy to use mineral oil if the brakes are rebuildable and a good enough quality without being super hard to get. TRP maybe the answer, but my newer Hayes work amazing.

Shimano is just shit for spares all around, really. It has nothing to so with mineral oil, they just can't be asked to do proper spare part handling. All good manufacturers of bike components deliver good spares. SRAM has piston and seal kits, Hayes used to have it (don't know how current Hayes is), Magura unfortunately does not anymore ("If your caliper is worn out, please replace"), Trickstuff offers both DOT 5.1 and Mineral oil seals for their C21 calipers (XC type) etc. For crapmano, you can buy 3rd party alloy pistons from Aliexpress with seals for the pistons. Changing these is not easy, though. I gave up on my girlfriend's commuter.

Rebuildable products is very important in my opinion. Therefore I do not get Shimano products unless I really have to.

It is and Shimano's policy about this is properly shit. On the other hand shops and techs don't have the time to replace pistons. It's more of a DIY job. Which I happily do.

As for longevity, not sure about shimano, but I ran a pair of Formula Oro K18s for... 5 or 6 years without bleeding them and didn't have problems. And I bought them used (no idea how old). And a friend of mine used them after that as well, had some problems (for example the lever reach adjust bolt stripping) and the same brakes are now used with new hoses (original ones seemed to get clogged and couldn't be bled) on his GFs bike. On original pistons and seals. Not on original oil though.

As for sram, 2 and a half seasons in, Code RSCs work flawlessly (bled them about a month ago for the second time, after doing an initial bleed when I bought the bike), while I did replace all the pistons on my Guide RSs before that after 3 or 4 seasons (not all at the same time).

What about Hopes? I’m loving mine. Easy to bleed. Small parts easily sourced from online shops (not everyone likes that though).
From my understanding, they keep spares for all their products for a very long time.

I can't deal with Hope... Love the feel, the power, the look and all but there are two major drawbacks for me (experimented on a pair and shared with other users) : when the brake starts to have a loss in power, modulation or other, in short when it starts to fail, I experimented that it's not possible to have it running well again (despite bleedings, chaging seals, pistons, etc...).

Plus levers being machined, there are some angles which wait your knees or hands to scratch them hard...

primoz - i miss the OG formulas!! i ran formula oro puro's on a bike i shuttled often - they took more maintenance free abuse than shimano, sram or even hope given the same conditions.

i think we all need to come clean on brakes though - pretty hard get bad quality brakes past a certain threshold. how much maintenance? how long will they last? 100% rider and condition dependent. 220 lbs rider vs 120 lbs. 10 minute dh runs vs flow single track. wet vs dry. brake jammer vs the touch of an angel.

I know that the Gamux bike is posted because of the dorado and gearbox but

when will Pinion give us trigger shifters? Instinctiv bikes made some but aren't selling them aftermarket

From what I have read and understood, the Pinion gearbox needs to have the mechanism pulled in both directions. That's why they use the gripshift, as it is 'powered' in both directions. Triggers usually require a return spring in one direction.

It could be made, but I'm not sure how reliable it would be. I'm really interested in what Instinctiv has done, but the Pinion gearbox is ideal for electric shifting. Supposedly in their assembly line final check they use a powerful motor to shift the gearbox under full power. The mechanism can take it, reviewers saying you need to let up on the pedals to make a shift is just not using enough twist on the gripshift. That's why a trigger could be unreliable, without knowing what you're doing or how it works you could have a ton of unsuccessful shifts. It's not a problem if, ou understand the mechanism, it is a problem if you do and then bitch about it to your friends, on the Internet, etc. And that's bad publicity. That is the main issue.

Plus I don't see gearboxes getting popular with the way 12spd drivetrains function.

Not cheap, not cheap at all... And hardly compatible with dropper posts.

For that kind of money it should be possible to have an electronic version, for sure.

Kindernay is doing something similar with their internal gear hub, only doing it hydraulically, and also too complex and expensive. IGH is not something for mountain bikes either, though.

I will said it´s something like a new Scale, the seatstay angle it´s seems like a front suspension only bike and is too thin for me to be a full suspension bike

The bike in the photo for sure is not a full suspension and probably not a xc bike either. Given the cassette a gravel model makes sense.

Regarding the bold look (ha, a pun), carbon only then?
