The basic idea with Aeroe stuff is that it’s a dry-bag luggage rack system that fits every and any bicycle. Even full-suspension mountain bikes and e-bikes. It’s not meant to be aerodynamic. Or super lightweight. Or super quick to install/remove. It’s kinda not meant for the hardcore bikepacking zealots. It’s meant for normal people who may wish to go on an adventure now and then with more stuff than a CamelBak can contain. Installation and removal were both actually pretty simple. Just a 5mm Allen key is required. The whole operation took five minutes. In use, the whole shebang has remained rock-solid and hasn’t failed to fit any bike it’s been tried with (e-bike, full sus, gravel bike, high school commuter). The dry bags have done their job and are holding up well with no signs of tears or fraying anywhere. There may be sleeker, lighter luggage systems out there but that’s not the point. This genuinely works simply with any bike.

A super light saddle with carbon rails is not something I’d typically be into. Especially one that isn’t even really intended for mountain biking (the Latus is apparently designed for gravel riding ). What attracted me to this posh perch was sort of a personal ‘proof of concept’. The Latus has a wide, yet short profile. It has a broad flat rear (where you sit) which I get along with. It has a very snub nose because… well, for my intentions… because you no longer ever sit on the nose of a saddle anymore (now that mountain bike seat angles are decently steep), so the nose is redundant. All it does is impair standover stuff and get in the way. Get rid of it. After a few months of testing, I can hereby confirm that this saddle shape is The Future. We just need a version that’s got a smidge more padding and is a heck of a lot cheaper.

In one of the more confusing decisions in branding, Sinter only makes organic brake pads. And that’s fine by me. I only use organic pads if possible. Principally because they offer more feel than metallic sintered pads. They also feel more usefully powerful for most riding scenarios. Organic pads are also much less prone to annoying squealing and honking noises. I really rate these pads from Sinter. Green pads are great in the front for braking late and/or hard. The Blue pads have found a home in the rear brake as they’re a bit longer lasting – the back brake sees more dragging as well as getting more ‘trail splash’ hurled through it. Both sets of pads have been pleasingly quiet in use. I’d generally really urge you to try premium pads if you’re feeling less than impressed with your brakes. Sinter ones have really improved several initially mediocre brakes (OEM pads?) that have been on test bikes recently. Not cheap, but cheaper than new brakes.

Madison Enigma sunglasses

Good glasses are good glasses. Sometimes they cost three figures. Sometimes they don’t. All too often the not-three-figure options aren’t much cop, either from an optical or durability point of view. This is especially true of interchangeable lens designs. I’ve worn these Enigma glasses on almost every ride since mid-October (that is a lot of rides) and they’re still pretty much like new. I’ve used the clear lens a handful of times and the dark/mirror lens er… never (UK resident init). It’s the amber lens that has seen almost exclusive use because it just works and is nice everywhere. There’s no fiddly latch mechanism if and when you do need to change lenses – the bendy frame just opens/closes apart. Simple. The posable nose piece is handy when you need to increase airflow on more humid rides but in general, the Enigmas have been very good at not misting up during exertion.

Shimano GF4 (GF400) shoes

Let’s get to the point: are these better than the similarly priced Five Ten Freerider Pro? For me and my feet, yes. Definitely. I don’t know whether it’s my feet that have changed, or the last (the fancy word for ‘foot shape’) that Adidas-era Five Ten is using these days, but I no longer fit Five Tens. They’re too narrow now. In terms of pedal feel and traction grabbing, Shimano’s new ‘Ultread’ rubber-soled shoes are several leagues better than their previous shoes. I’d go as far as saying it’s the best all-round compound out there in fact. In terms of construction quality – and also shock-absorbing aspects – the Shimano GF4 is every bit as good as the hallowed Freerider Pro. I’d even say the asymmetrically raised ankle collar and toe cap give this shoe the edge over its rival. The one and only thing that they struggle with is style. These dark blue ones especially. The all-black ones are better, albeit boring AF. I’ll take function over form though thanks.

Muc-Off eBike Drivetrain Tool

For those who don’t know, oiling the chain of a pedal-assist bike is more complicated than on a regular bike. Essentially, you backpedal the crank arm and the chain doesn’t move because there’s a freehub in the motor as well as in the rear hub. This means you can’t do the usual backpedal-while-drizzling-oil-onto-chain lubrication method. Sure, it’s possible to jam an Allen key into the chainring bolt to get the backpedal method to work (the crank arm engages with the body of the Allen key thus making the chainring backpedal successfully) but the Allen key usually fouls the pedal body making backpedalling really awkward. It also leaves a nasty mark on your crank arm. This tool from Muc-Off does the job of the jammed-in Allen key but does it without awkwardness or marks. It’s a product that elicits celebration and ridicule in seemingly equal measure. I am glad it exists. It’s one of my favourite things in fact.

Hyperlocal Weather App

Price: Free with ads (£6.99 ad-free)
From: Apple Store or Google Playstore
Tested by: Benji for several years

Being a British biker means I am probably more weather-focused than 99% of people who aren’t telly weather forecasters. I like my weather served to me in two ways. A longish term overview done relatively simply. And an immediate in-depth what’s-happening-in-the-next-couple-of-hours granularity. The Hyperlocal app does both of these very, very well. It’s fast, clear and accurate. It’s a particularly good weather app if your main concern is rain. Knowing if and how much it’s likely to rain helps me prepare in the longer term (tyre changes?) and in the short term (jacket or just gilet today?). It’s the one and only weather forecast where I actually comprehend the likelihood of rain and rate of rain, due to the bar chart and trend-line graph in conjunction with the satellite radar imagery (that only displays rain cloud). The free version of the app is fine. If you get really into it you can splash out £6.99 on the full version to ditch ads, unlock a few nice-but-unnecessary features or just to support the people behind the app.
