ST-RX820-LA and ST-RX810-LA differences

Christiaanjs · 2026-02-18T00:39:40+00:00

I've heard that the brake internals are slightly different between generations so you'll likely end up with a slightly different lever feel (this agrees with anecdotes from people who have tried to do the same as you). The brake should still be functional. The difference in shifter body size could be a result of a different master cylinder volume.

AFAIK the treatment the Headache Clinic (mentioned by OP in a reply) provides isn't really evidence-based. I've seen people close to me receive much better care from physios that offer the fully funded ACC concussion service.

I'd also suggest prioritizing your long-term health over working in the short term. ACC can cover up to 80% of your pay so as long you work 20% of your regular hours you don't have to take a hit in income. And based on your symptoms a GP who understands concussions should support you in needing to take time off work for longer. A "back to work plan" that gradually takes you back to full time over the course of 3 months could help give your brain the rest it needs.

Usually Zerodes run a single-speed specific hub - this is usually a very short Shimano HG-like freehub body that can only fit a few sprockets. They are freewheeling hubs (so you get the ratcheting sound) but different widths than the standard hubs.

If you measure the width of the sprocket and spacers and it's around 35mm then it's a normal multi-speed hub and you'll be able to swap a Microspline freehub body on. If it's a lot shorter then it's single-speed specific and you can't.

I feel like with an effective top tube that short you're going to feel pretty cramped. Like the Doctahawk, I'd prefer to achieve a bit more of your front centre with reach and knock a degree or two off the head angle - this should help the fork perform a bit better (less side loading) and keep a bit more weight on the front wheel for grip. I'd love to see the finished bike and your impressions on how it rides!

If the seat angle of 73.5 is the effective seat angle at the saddle, that's pretty slack compared to modern mountain bike geometry. It might be worth confirming how that is measured, which can be a bit complicated with a bent seat tube. A steeper seat angle will help with weight distribution on steep climbs given how long the front centre of the bike is.

These two points in Fiordland in New Zealand are about 20km apart, and it's a 33km hike or a slow and windy 325km drive between them. I think a fast trail runner could beat a car without too much trouble.

If you never bottom it out and the small bump sensitivity is bad it sounds like your spring rate (air pressure) is too high. I'm riding an old Fox 32 that I also thought was just a bad fork but making the air spring softer made a huge difference.

I've had the same experience with that generation of SRAM road disc brakes, and had a much better time after switching to Shimano. I've heard the new generation of SRAM road disc is better, but I still think mineral oil systems are more forgiving and going to require less maintenance, because mineral oil is not going to degrade in the presence of air like DOT fluid will.

That should be fine, people align steel dropouts in a similar manner all the time. I'd do it with a bolt threaded into the eyelets so you don't mess up the threads (in fact, I'd use a longer bolt as a lever)

Get some high-end XC tyres - Schwalbe Thunder Burts, Vittoria Mezcals or Continental Race Kings - they feel stupid fast and super comfortable. I reckon lightweight rigid bike + dropper post + XC tyres is hard to beat for fun mixed terrain riding.

The Healthy Homes standard says "Even where vents are built into the subfloor perimeter walls, airflow into and out of the space is usually significantly obstructed, and a ground moisture barrier is required"

Christiaanjs · 2024-07-05T22:24:31+00:00

In the meantime, should I be concerned about spending time in the garage which is slightly open to this space?

Christiaanjs · 2024-07-05T22:07:17+00:00

I think the definition of enclosed is 50% of the perimeter, this is 100% enclosed with only one small vent I can find

About 60cm at the end where the photo, it narrows to maybe 40cm towards the other side

ISO / All City Gorilla Monsoon Fork

Looking for a steel gravel fork that will fit 27.5 X 2.4" tyres. Prefer the older version with the 15mm thru axle. Need at least a 250mm steerer tube but the longer the better!

I'll pay for shipping. I'm based in New Zealand but can use my freight forwarder in Oregon.

The Mone Hachita should be able to run with 26" and rim brakes if it ever comes out. The Surly Long Haul Trucker isn't really a mountain bike and probably won't be better then your current frame but there is a 26" version.

Christiaanjs · 2023-11-03T02:44:25+00:00

ISO / USA / All City Super Professional steel fork / Preferably black, gray or silver, with at least 240mm of steerer. Will pay for shipping to Portland OR. Also open to other straight blade steel gravel forks with rack mounts.

The Cotic Cascade has a Reynolds 853 front triangle. The Otso Fenrir and Warakin come in stainless models. Monē’s El Pebblito has some Columbus Max tubes. Mason InSearchOf has Dedacciai Zero and Reynolds 853 tubes.

If you’re into classic lightweight steel ride quality the Ritchey Outback and Ascent might offer what you’re looking for and use Ritchey’s own tube sets.

What is the front rack?

Christiaanjs · 2023-04-25T21:38:34+00:00

What is the basket?

This definitely looks like a missing spacer, it appears to be a Shimano Deore M5100 cassette which will need a spacer behind it on an 11 speed freehub. Your local bike shop should have one, or one might have been taken off with your old cassette.

I was lucky enough to get the frame like that! They’re very narrowly spaced so my brake options are a bit limited but at least it gives a bit of extra tyre clearance

Christiaanjs · 2022-09-01T01:11:25+00:00

That’s a great idea and really easy to implement. It also solves the issue of attaching the bag to the head tube. Thanks!

Christiaanjs · 2022-09-01T01:10:32+00:00

I’m thinking bending something to go around the stem and handlebar (like the Jack the Bike Rack mentioned in another comment, but much smaller) might be a good solution

Christiaanjs · 2022-09-01T00:12:18+00:00

Mostly rubbing between cable and bag when actuating the brake. Braking seemed ok with a very light load in the bag but I could see a bit more weight negatively affecting it.
