Assuming that you're talking about cleats on your shoes, there are three main attachment systems. Left: 2-bolt, Middle: 2 or 3 bolt, Right: 3 bolt. Notice how the one on the left has a chunkier sole. The two-bolt option is used for SPD which are popular with MTB, commuting and touring cyclists. I use 2-bolt SPD shoes on my audax bike because I'm able to ...

Yes there are lots of different options with pedals (it's a bit easier with shoes), but they can be summarised quite briefly. Types of pedals: Flat - a standard pedal on many bikes Flat pedal with toe clips. So you can still use any shoe, but the toe clip holds your shoe in place on the pedal. "Clipless" pedals - where both pedal and shoe have a some kind ...

Ever had that "this has to.... be the top.... oh sh$%.... it's a crest.... there's more...." feeling. Knowing altitude lets you pace your climb and arrive the the top without over (or under) doing it. Imagine riding flat roads without knowing speed or distance - it can be done, but to maximize training effort or race performance you need to know ...

Historical Contingency Looking to history earlier versions (e.g., Garmin Edge 305 and Edge 705) came with barometers for elevation. This was long before Strava, and during a time when you did all the analyses on your own computer. Some analysis software supported getting elevation data from other sources, others didn't. And at the time accurate and free ...

I find when climbing that horizontal speed is fairly meaningless but vertical speed can be quite helpful for keeping you going and/or interesting. When you know a climb is 1000m and your computer says whatever-kmh, you've no idea what that means without maths and knowing the gradient, 1000vmh means an hour to go, 500vmh, 2 hours... and so on.

Motorcycles are mostly used for media (video and photos) and sometimes for support (they can have a limited number of wheels; I'm not certain if they are "neutral" or team specifics. The motorcycles will be mixed in with the cyclists; the drivers are highly skilled. The cars are for race support; there are team specific cars with spare parts and ...

Yes, absolutely. Spend an extra 20 dollars on good tires and you could save yourself 30 dollars worth of tubes. Plan on spending somewhere around 40 to 50 dollars a tire. Even if tubes were free, the money is worth saving the hours spent on the side of the road dealing with flats. Look for tires in the 'training' or 'commuting' category, for extra puncture ...

Its extremely unlikely for an inner tube to just burst. It sounds like you are suffering from punctures. There are two types of puncture; the first is an object penetrating the tire and inner tube, and the second is a 'pinch' puncture where an impact causes the inner tube to be pinched between the tire and rim. Many bikes (even expensive ones) come with ...

There are multiple types of valve extension: The extenders you have relocate the valve core. The other kind are a plain tube which tapers with a similar profile to a normal valve, and screws onto the valve, over the existing valve core. Once the tyre is inflated you can remove the extension and tighten the valve-lock-nut.

I would suggest your frame may be a bit small for you. I'm slightly shorter than you and I have a Scultura 906 in a 54 cm frame (size on the frame sticker says S/M). The longer stem may assist, however it may put you in a more race position which could lead to the neck pain. As for the calf cramps this could be a couple of things; 1) seat height too low, 2) ...

As I've said in other answers, the right tire pressure function of you and your bike and your terrain. You'll have to play with the tire pressure to balance the ride quality.Just because the tire says pressure x on the sidewall doesn't mean it makes any sense running the tire at that pressure since it might just give a bouncy ride which compromises your ...

Yes, better tires can help prevent punctures. It has already been mentioned that there are tires specifically made to enhance puncture resistance. One thing that has not been mentioned is that better tires also have stronger sidewalls to offer more tire support when going over bumps and thus better protect against pinch flats. (Once, I had a cheap tire with ...

Both bicycles have similar components (the Gravity slightly nicer drivetrain, but with a cheapo looking seatpost, etc) and are manufactured in similar facilities in China or Taiwan. The Trek will be set up and fitted by your local bike shop, which will be very helpful if your local bike shop is competent (some aren't). The Gravity will be set up & ...

You could try adding sealant to your tubular tire. Tufo Tire Sealant, Stans's No-tubes (and other tubeless sealants) can be used to deal with small punctures. Most recommend not using the sealant as a preventative measure, but more so as an after the fact solution to quickly fix punctures on the road. However, Tufo Standard tire sealant says that it can ...

The spring tension of front derailleurs is not normally configurable. Addressing your difficulty shifting up, have you checked whether the High limit screw is preventing the mech from moving all the way, forcing you to stretch the cable until the shifter reaches the ratchet point? The shifter is normally able to freely pull cable slightly beyond the ...

The convoy of team cars driving behind the riders are there to provide support to the cyclist, like food, clothing or mechanical assistance. The sequence of the cars is determined by the ranking of the riders, e.g. the general classification in a stage race. During a race riders will drop to the back of the bunch (peloton) usually to collect new bottles ...

If your GPS bike computer doesn't include a map[1] and you're navigating from a topo map, having the elevation can be very useful for making route decisions. In the bad old days before ubiquitous GPS, by far the most useful navigation tool in the mountains for me was a barometric elevation watch. That and a topo map was my go to tool 90% of the time. Of ...

I also would recommend finding tubes with valves of the correct length. However, if that fails, I've had success using a presta to schrader adapter. Often with shorter valves, there won't be enough room to attach a pump head, but there will be enough to attach an adapter, which you can then use a pump that works with schrader valves. Most pumps have the ...

If you dont have much experience with a bike setup and maintenance, then get a old-stock bike from a local shop. The amount of money you will pay extra will be equal to the money spent for putting the online-bought bike together. Also local dealer will be able to find you proper bike size - just because you are X inches tall, doesn't mean you should by ...
