Over the past few years I've been decarbonising our house in Melbourne: heat pump everything, solar, home battery, induction, EVs, and no more gas. A @billmckibben.bsky.social @ezrakleinbot.bsky.social interview inspired me to share my reasoning, detailed process, and results. crossgeared.com/decarb
Internal cable routing and one-piece cockpits are terrible value, almost guaranteed to compromise fit and a bad idea for anyone who isn't paid to race a bike. Good chance taking your phone out of your cargo bibs will make more aero difference than any of this marketing nonsense. youtu.be/LPTptOYT6Jg

Two responses to high energy costs in U.S. and AUS agriculture. One is reactive and piecemeal, the other looks to the future and perhaps an eg of what good energy policy can do. There’s clearly more nuance, but the contrast is stark.

Farmers can now produce more of their own energy than ever – but will they?
Self-reliance is important for many Australian farmers. But could farms ever become self-reliant in energy?

The electricity market generators use batteries to cut their costs and I've used my solar/home battery to negate their peak ToU pricing, even on a cloudy Melbourne winter day. What is ToU pricing? Why does the cost of electricity change thought out the day?

Two updates: I've been looking into the effects of ToU energy plans and how they interact with scheduled loads like EV charging, home battery forced loading, and heat pump water heater scheduling. I've also organised all of this into the Home Decarbonisation Project. crossgeared.com/decarb

I've enabled forced loading on my home battery to supplement solar, reduce wintertime peak energy costs, and shift grid demand from the evening peak to earlier in the day when there's likely more grid solar production. Is it working?

It's 2026, so my road tyres are now wider than my CX / gravel tyres. Which is more fun on singletrack, the 38mm Corsa Control or the 35mm Mezcal? 🤔

BikeRadar is hit or miss, but I do listen to some of their podcasts and I particularly like Warren Rossiter's take. I appreciate his pragmatism around endurance road bikes and dropbar cycling in general, and this is an excellent example. Just do yourself a favour and use reader view.
I’ve worked in cycling for nearly 30 years and I’m done with Tour de France bikes – here’s why | BikeRadar
Cycling brands market the bikes at the Tour de France as if they’ll make us better. These are the machines that’ll allegedly improve our riding lives. To me, it doesn't add up.

This one doesn’t have any inspirational wall art, but does have some burned paint from a torch and a broken Garmin mount. I still had a good ride. 🤷♂️

Someone should let Michelin know there's an XCO/XCC race going through their ad. I think the old ads were somehow more tolerable with Rob Warner screaming over the feed. These tree sponsors are a bit much.

My '09 #KonaBikes Unit. A #steel #rigid #29er #singlespeed with a #dropper and carbon wheels??? 🤯 About 10 years in its current configuration, many times cracked, many times fixed, doesn't need a fork/shock service every 50 hours, very fun and still one of my favourites.

It looks like #hookless rims may be on the way out (www.youtube.com/watch?v=ftRD...), at least according to Josh Poertner at #Silca. Now, can we now do the same for internal headset cable routing?

Policy that disincentivises EV uptake is counterproductive and an at odds with reality. Claiming EV drivers are getting a 'free ride' ignores the massive externalities and cost of burning fossil fuels. This headline is intellectually dishonest. #carbontax www.theage.com.au/politics/fed...
Beginning of the end for EV drivers’ free ride on road charges
Jim Chalmers and the states did not specify how a new levy would work, but their statement said it should be “as simple as possible”.
