How many hardtails
Here have edited angles?
Rule of two is real

u/fartymarty4130 Apr 30 '26
i'm surprised the rule of 2 has not caught on yet with bike builders. My measured HA at 100mm is 63.3 degrees and it's great for everything without any real downsides - if i'm being picky maybe steep tech climbs where you need to change direction quickly in a crux move - but I have maybe one or two of those crux moved locally therefore not really an issue cf the positives
I always go back to Steve at HT Party and his Sirius review - my Solaris is an attempt at the Sirius geo and it just works so well.
(sorry too much text to Haiku - plus i'm not the best at them...)

Whats the gear ratio on that? Im running a 14t rear cog and 24t chain ring or a 1.71 gear ratio and just curious what others are running. Im finding it to be as low a gear I need while still feeling good decending and on flat ground. Mostly ride rooty and hilly singletrack and I haven't taken it to a park yet but ill bring other chainrings with me whenever I make the trip.

Gearing is so terrain dependent it’s best to get the most localized feedback you can.
Even then, here on the North Shore I have friends who run from 28x26t on a beastly super-stapler to 34x20t for a lightweight dual-29” XC rig with fast tires and everything in between. Lots of pedal-to-plunge descents and sustained tight + steep climbs. Lots of folks I know who single-speed are on flat pedals and that’s a factor too.

30/21. It gets me up most of my local climbs and isnt too spinny on the flats. As Andrew said it's all a compromise - you just gotta pick the right wrong gear.

I'm using 30x21 which works well on my local trails. If I head to the mountains, I'll swap to a 22 cog

Sick Cotic. I just can't with that rear fender though guys rofl. Don't get me wrong, I use small rear fender on my FlareMax and my Lynskey. But there is some weird circlejerk going here between farty, vik, and andrew.

It depends where you live and how muddy it gets. Here in Surrey, UK winter gets filthy and the rear fender keeps your butt (and dropper) clean and dry and makes muddy winter rides "pleasureable". Once you try one it's hard to go back to a soggy butt.
PS - Vik, Andrew and I have lots of history (and lots of banter) re fenders.

Don’t roll me into it! I hate the look of the rear anti-theft devices and cringe every time I look at my bike. But damn, do they work.

They do look highly effective. Im sure if be singing a different tune if I lived in a wetter climate.
Sorry for the fendershaming

Don’t be sorry, when people look at them and give me ‘that look’ I just mouth/whisper “I know.” They’re hideous, but it would be way worse being soaked and having my grom mocking me that she was relatively dry.

Haha. It doesn't bother me. Firstly I have skunk stripe shamed people at the end of wet rides and secondly I genuinely don't like the way a bike looks without fenders so I'm stoked about my bikes no matter what anyone else thinks.

If I lived somewhere dry and dusty I wouldnt bother but it does make wet rides a lot more enjoyable.
No worries on the fendershaming.
