With multiple bikes, locking them together prevents them being picked up or ridden off. The latter is often the biggest risk when camping - simple opportunism. A reasonably long cable lock would lock all the bikes together (also outside cafes), and if you use it in an awkward position (down near the chainrings), getting cutters to it would be noisy, and ...

GCN had a funny take on this recently: Gravel bikes exist because mountain biking is now boring. Or to give slightly more nuance, mountain bikes make it so easy to ride over difficult terrain that they remove the challenge. Coming at it from the opposite direction, road cycling may be losing some popularity because A) roads in many places are poorly ...

"a decent chunk of money on one bike" this is a very slippery slope. If this is your first bike, look for a used hardtail MTB for relatively low cost, and simply store any leftover money. You'll want to buy accessories over time like helmet, tools and lights and so on. Ideally the fork would have a working "lockout" lever, to disable ...

For me, a gravel bike is the perfect commuter bike. Before, I had a road bike and a hybrid (normal) bike. On nice days I could maybe use the road bike to work, but mostly I would use the hybrid one because of rain/snow, having to carry stuff or whatever. However, going up the hills back home, and even the flats, the hybrid feels sooo slow and heavy. So I ...

This is why people recommend not going to Halfords. (For the benefit of people outside the UK, Halfords is primarily a car accessory shop, which also sells bikes). If you go to a proper bike shop, the staff will insist on fitting the bike to your properly, rather than coming up with excuses not to. They'll also let you take the bike on a proper test ride, ...

Google 'cyclocross'. The primary difference between a road bike and a CX bike is the size of the tires. You can ride your road bike anywhere your skills will allow. There are some gotcha's though. Skinny tires only have so much traction. Gravel flats won't be an issue for all but the lightest of race tires, but pinch flats from hitting larger rocks at ...

You cannot get a higher gear ratio by replacing the cassette. The 11 tooth sprocket is the smallest you can get on a compatible cassette. (Systems with 10 tooth sprockets exist but use a different freehub design). The issue is that you have 46/30 tooth sub-compact chainrings (I looked up specs here). Which are giving you the low ratios. This is common on ...

I understand that around 20% of the energy while cycling is lost by the deformation of the [tires] No not really. Rolling resistance will increase linearly with velocity while drag increases with the cube of velocity, so rolling resistance is not a fixed percentage of total power lost. At higher velocity drag will completely dominate. use plain tires (no ...

I sell that bike at work. The road/mountain FD mismatch functions very badly. We've had to replace the front derailleurs with road models. The total throw of a road shifter isn't enough for it to shift well and not have rub anywhere. It's terrible. It can be made to kinda sorta work if you accept rub in the lowest gear. But, that shouldn't be acceptable. And ...

As other answers and comments have indicated, you can successfully ride a road bike on loose gravel. There are five main factors, and they are all interconnected: The depth of the gravel. The key to riding in gravel is smooth lines. Avoid sharp turns: the deeper the gravel, the more your front wheel digs in and accentuates any steering movement you make. ...

In all honesty, you can use any disc you like, and from practically any manufacturer as long as the dia. (and fitment type) is the same.

I think you are asking two separate questions: What's a gravel bike and why are they popular? Why are off-road tires designed they way they are? (Which applies equally to mountain bikes and hybrids) Gravel bikes have longer seat stays and more relaxed steering geometry than road bikes, which makes them a little more stable on loose surfaces. They have ...

A few considerations: You have two competing characteristics here: You want a bike that excels at the niche you enjoy the most. You also want the bike to be capable of handing the other niches to an extent you’re happy with. For example, if you enjoy road riding the most and therefore pick a road bike, you won’t be very capable off-road even though you ...

I would suggest a Pacsafe Security Web or similar product to cover your gear. It is basically a net made of small gauge steel cables. It is designed to cover a backpack along with a long cable to secure it to a tree or other object. As far as the bikes are concerned I would suggest each rider carry a 2 meter or 6 foot cable. If it is a keyed lock make sure a ...

My theory and it is just a theory. In the U.S. at least there has been a proliferation of unpaved bike trails due to the conversion of abandoned railroad rights of way to bike paths. They are for the most part either flat or have a slight grade. Most of these trails are too uneven for a conventional road bike. At the same time they are not much of a ...

Now based on that, I was wondering if there is any estimate on much gravel bike tires (with some light tread pattern) might contribute to the loss of energy compared with road bike tires (plain) for the same conditions (dry, plain and smooth road). You don't need to estimate. You can measure. For example, here's one gravel tire: https://www....

The strength of a carbon fiber composite frame is not the problem. There are many CFC gravel, cyclocross and mountain bikes, so obviously CFC as a material can take the impacts. If you ride a road bike on a harsh, bumpy paved surfaces it does not break. If you want to be convinced of how tough CFC frames are, google for videos of the testing that ...

When riding on the hoods reducing the reach of bars is equivalent to using a shorter stem. Only when riding on the tops a shorter stem will lead to different steering compared to shorter reach bars. A change of 2 cm to 3 cm will change steering. However, it is not so dramatic that you will hit the dirt right away. Especially on gravel bikes that typically ...

What is called a "gravel bike" is really a new word for a cyclocross bike, but with maybe a tad less aggressive geometry. And cyclocross goes back pretty much to the beginning of bicycling, as the first races were held on unpaved courses and no roads were paved yet, or at best cobbled. The original road bikes looked a lot more like today's ...

My experience with swapping wheels is disappointing. I had to adjust the derailleur (limit screws, cable tension) and rim brakes (due to slight difference in rim width and dish) every time I swapped wheels. Maybe if you have exactly the same hub and rims on both wheels it will work better. I think my derailleur adjustments were necessary because the cassette ...

There are no Shimano brifters that are 2x11 compatible, but Microshift manufactures some. I use a Microshift SB-110 (1x11) and a bar-end shifter for a drop-bar 3x11 setup with an XT rear derailleur (RD-M8000) and XTR front derailleur (FD-M9000) with no issues. Here is Microshift's product page for the SB-110: https://www.microshift.com/en/product/sb-m110/

Braking is always stronger from the drops than the hoods, as you noted only your lower fingers have mechanical advantage when braking from the hoods, when braking from the drops you have much better mechanical advantage for all your fingers. That said, when properly set up, you should have no problems locking up both wheels on gravel from the hoods. You ...

There are several answers to this question. The one is fair use. Like you wouldn't ride a roadbike on a severe downhill or in a cyclocross race. Or have a 150kg rider on a lightweight racebike with flimsy, sparsely spoked wheels. The other answer is given by the limitations imposed by the manufacturer of the bike and the components, mainly the wheels but ...

The logo is from a Carrera (Halfords) bike, so the wheel will have been on a Carrera originally. You can google the Carrera logo and see that the C is styled in the same way on their full logo. The 29 is simply referring to the wheel size, a mtb '29er' which has the same ETRTO rim diameter as a typical road/gravel bike, though widths can vary.

Who to believe? You can believe that the shop owner believes that tubeless is not for him/her. But that does not mean that you are in exactly the same situation or have the same needs. Here are some high level steps for arriving at a solution that works for you. Read and listen to what others say Look for information that matches what you intend to do and ...

The specific word you need is 'rotor'. If you search for 'Shimano 105 disc brakes' you tend to get the calipers rather than the rotor (which is confusingly actually the 'disc' part). The latest 105 series rotor part name is SM-RT70. See the Shimano 105 series page. There will be other rotors that are compatible with 105 calipers, in case you need a 6-bolt ...

28mm wide tires are perfectly suitable for riding hard-packed fine gravel trail surfaces. You do have to be more careful when braking and cornering than on tarmac as the top surface is loose. Larger rocks and potholes should be avoided of course. As the size of the gravel particles gets larger or the depth of the loose gravel top surface gets deeper the ...

You may start breaking spokes in the rear wheel after putting some miles on the bike. That seems to be where the effects of load shows up first. You can plan to mitigate this by budgeting for a new rear wheel. If this is the bike you are talking about it has 28 spoke wheels. You'll want a 32 or even a 36 spoke replacement wheel, hand built. You don't have to ...

Many places have a lockup area suitable for securing bikes overnight, this would be my first choice. Depending on the culture where you are, in the crowded camp ground environment, striking up a conversation with your neighbour is likely a big. If you are seen talking to them, your bikes become a much riskier target. (and you never know, the last touring ...

The subtle use of the "Bisley Mine", which uses a trip wire to fire a BLANK 12 bore cartridge could be just the thing! Wakes you up and scares the hell out of the thief at the same time. On Amazon or eBay.
