I forgot one: 6) He believes people cannot understand his idea, despite supposedly being based on basic mechanical principles.

The problem is not his design but his explanation of why it works. There's a lot of common things that should always ring alarm bells in any technical discussion and generally indicate that the person making them doesn't understand what's going on. 1) He discredits an established theory that has logical assumptions, is based on basic principles and has been...

Matt Beer can ride a bike but he has said some bafflingly wrong shit in the past when talking about how bikes work. He's not a great resource for technical stuff IMO. edit: and if you disagree then go and read his "article" about fork offset and compare it to how steering geometry actually works. It's confused and mostly backwards.

You mess up in seeding you start where you start. Own it. You are going to have to deal with slower riders on course. Better luck next year. Does matter if you are AG or some never was has been local. Life ain't always stacked in favour.

It's not really possible to lube the seals from the outside but you can lube the interface between the piston and caliper bore. This needs to have low enough friction so that just after breaking, when the pistons have been pressed against the bore, the seals can pull them back without slipping. If the seal slips then the pad stays...

If two people can comfortable hit it and it comes with a huge time advantage it gets to the point that the entire field has to take massive risks to be competitive. The Jr's are just that, Jr's. They are not professionals and outside of a very select few I bet most are not getting a paycheck. Closing one feature will have zero effect on the racing for the weekend...... Having to chopper a rider or two off the course during practice will have a big effect on everyones race weekend.

It sucks to buy a new bike part that has problems or doesn't live up to expectations. I use galfer red pads in my gravel bike and there are always circles worn into them where the paint has come off but it doesn't seem to have any impact on the brake's performance. If you don't like the paint coming off...
My guess would be they've introduced a 17mm piston and have gone 18/17 for GR (+6%) and 17/16 for the TR (+6.5%). What is surprising is that they have decided to use the same pad (V4?) in both because the smaller pad in the E4 was one of the main reasons it felt different to the V4. It's good they've...

You are so lost in the sauce. Like 4 different people gave great explanations of how flex stays work and you dismissed every single one, but want a "data driven discussion" when you can't comprehend a literal Microsoft paint diagram. Now you don't like "buzzy undamped coil spring", this is comedy gold. @CascadeComponents Can i formally apologize for this member of the forum and please say come back to discuss things with us Vital users that don't have a crayon missing from the box.

Flex stay can't rebound undamped. It doesn't move without the shock moving.

Until they get the rotor arms orientation right they cannot be expecting to be taken seriously. And red paint? Seriously? What is this fast and furious vol.I? Oh, grimeca wants to have a word with you about that too lol. Gosh I'm so negative.

Adding to this, the heavy duty with lightning have a bigger friction area compared to the normal 2.3 thick one piece, somehow every place that sells Hope as a picture for the one piece have the heavy duty with the lightning, which makes it confusing as it’s not what you’ll get. You can custom order those and it take ages to get them, also they’re quite heavy a 2.3mm one piece sits at 222gr for a 203 rotor, the Hd ones are over 250gr for the 203

Hope's disc options are quite confusing and have changed in the last few years. 10 years ago they had one piece 1.8mm, floating 1.8mm and 3.3mm vented. Around 2018 (I think - I bought a set specifically for the EWS race in La Thuile that year after experiencing fade there in 2016) they introduced a heavy duty disc that was...

What really matters is that I believe it's aligned. As long as I think it is, it's good enough.

Sorry, super frustrating experience. I’m not looking to vent about it, just curious about specific aspects of suspension performance. On the theme of learning, where else would you measure sag? At the wheel? How would this change things?

I've found that the gravity clips with a big platform and softer shoes with grippy rubber really help with this because when cornering hard the shoe will flex and contact the pedal so you can create some torque. It also means you can run the clips a bit weaker to make it easier to pop out when needed.

I'm not sure that is correct when talking about the torsional stiffness because for a given handle bar / wheel torque spacing the fork legs further apart will reduce the force acting on them, causing a smaller deflection of each leg and a lower rotation angle of the wheel relative to the bars. This is obviously simplified but in general...
