Get an inclinometer. They're not particularly accurate, but readout is instant and the price is right.

TCX and FIT are designed for fitness activities, so they can contain more fitness data than GPX. eg TCX or FIT supports laps (splits). So your device could record a new lap whenever you press the lap button, or automatically after a set distance, eg every 1km. Also they support pauses, if you want to stop the activity at one point, then start again later. ...

In track (velodrome) racing, visible cycle computer displays are generally not permitted. So the only funny looks will be from the commissaire who will request it be removed. This is the UCI rule: UCI CYCLING REGULATIONS TRACK RACES 3.2.005 Riders may carry no object on them or on their bicycles that could drop onto the track. They may not bear or ...

GPX files are XML files, which means you can edit them in a text editor. I use Notepad++ on Windows and TextWrangler on OSX, but you should be able to use the built-in Notepad or TextEdit. Don't use a word processor like Word or OpenOffice. Open the second GPX file in a text editor. Copy all the stuff between <trk> and </trk> inclusive. Open the ...

Instead of an actual GPS device, I would recommend buying a used smart phone, (The Strava app itself only works on either iPhones or Androids). A "Nothing Special" used smart phone you can usually find for maybe 40 bucks, depending on the model and brand. Download the app and just take the phone with you wherever you ride. It's not a fancy system, but it ...

It's a little more than 100$, but you could have a Garmin Edge 20 for 130$. Maybe wait a little for a special or something*. According to the post it's a good little computer and I personnaly enjoy using their Edge lineup. (* the website has a 10% anything coupon with their partner, might be worth a look, that would bring the Edge 20 to 117$, might not work ...

Most of the Garmin Edge series GPS cycling computers can display grade. The Edge 500 and Edge 800 (not the Edge 200) have barometric altimeters to determine altitude. You can then change or add a display data field to show the current grade. Funny you ask as I just put added the grade as a display field this morning on a hilly ride. It updates the grade ...

I don't have any experience with that particular unit, but I do have a Garmin Oregon 450, which is a "hiking" GPS, but I find it works great for cycling. I've found there's 2 important things to getting a lock on satellites. First, as you mention, is a clear view of the sky. The second important thing is don't move. The faster you are moving the more ...

Easy bit - Touch screens don't usually work when wet, you can easily test it, sprinkle some water on the screen and see how it goes. Because phones are high volume consumer goods designed as life style toys, not outdoor equipment, as far as IP ratings, I personally believe the claimed IP ratings are based on marketing need for a bigger number than the ...

I have a background in developing consumer GPS systems...... There is no doubt that a Garmin is a much better device for the job. On cell phones, GPS and associated functionality is the side dish - as in "would you like fries with your burger", on a Garmin, is the Raison d'être. Hardware wise, its a no brainier. First, as already mentioned in @armb ...

Just verified that the 510 can be attached to power while on/in use. It continues to operate. When the external power source is removed, it will give a message to that effect, but does not power down (like the nuvi/car versions do). Note that you (obviously) have to open the weather seal to plug in power. Also worth noting, the 510 will go into a different ...

You're only going to experience roughly a 10%, (maybe 20% max) loss of battery life. Unless you're planning on frequent century or all-day rides, the difference is relatively negligible. The average use case, a commute to and from work, or the average 4 hour group ride, won't see any difference because the battery life will go from about 8 hours on a full ...

It largerly depends on how you are marking the route in Google Earth and how you actually ride it. There are a couple of factors that introduce small diferencies when measuring distances and their effects are multiplied over distance, so the longer the route, the bigger the difference. The straight line effect For example, if I plan my route drawing a line ...

There are several phone apps / web sites you can use. They all have a free mode and a premium mode. A few of them are: Endomondo Last time I used this (a couple of years back) it was able to give real time updates and "coaching" on your performance. It can handle many different sports and activities. MapMyRide I haven't used this; some other people here do ...

Is it possible to upload tracks to Strava? Yes, you can upload your tracks to Strava. If your device is connected with Garmin Connect, there is an option to automatically upload your tracks after they're synched with the Garmin platform. https://support.strava.com/hc/en-us/articles/216918057-Garmin-and-Strava If you don't want to connect your device to ...

Since you can't fine tune your wheel size, the bike computer likely is estimating your wheel to be larger than it actually is, causing this discrepency. This is because a larger wheel covers more ground per revolution, so over time that adds up to a sizable difference and probably scales pretty evenly with whatever distance you cover. You may need to get a ...

You might want to look at the Biologic ReeCharge by Dahon. It says it hooks up to any standard dynamo hub. The nice thing about this is that it has its own battery. So the dynamo charges the internal battery and the battery charges your phone/gps/device. This allows you to charge while you are resting, as well as provide added protection against sending bad ...

Mobile is the way to go. Forget cycling computer. Cycling computer can't connect to computer wirelessly, your mobile can. I've stopped logging my rides on my mac, my mobile do this for me automatically and I can access the logs from anywhere. You get maps for free on your mobile from the internet and you don't have to update your map. You don't need ...

RANT - Do not read if you do not want to be offended. A lot of calorie burn questions popping up at the moment. The problem is biometrics has become the latest fashion accessory, and everyone (manufacturers and users) are clambering on the band wagon without stopping to think what they want this data for. Manufacturers want to sell gadgets and make money, ...

I've just started using an android app called IPbike. If you like tweaking settings and getting the items displayed just right it could be good for you; if not, look elsewhere. It can apparently sync with Strava etc, though I don't use that feature, and can import routes. It uses openstreetmap (a plus point for me as I've made a few contributions myself). ...

Yes. The Garmin Edge 530/830/1030 can be loaded up with extensive map data, and can give you live routing, even without a cellular connection. Wahoo's ELEMNT ROAM can also do routing on the fly. The Sigma Rox 12 also has extensive navigation functions. Probably others. There are some smartphone apps that can do this—I think the best-known are Ride with GPS ...

Garmin Edge 800, 810 and 1000 can be charged when exercise is active. You can use for example power bank or usb dynamo charger (ie. Busch&Muller E-werk, Luxos U light or Supernova The Plug). It is not recommended to charge anything with usb when it is raining. Also note that Garmin 1000's plug is in the bottom so cable might not fit when device is ...

From Strava's Help page : Energy Output Energy Output measures the amount of work you've done during a ride, expressed in kilojoules (KJ). It is a factor of how much you're pedaling, how fast you're pedaling and how much force you're exerting on the pedals (measured in W). Power output is most accurately taken from a power meter, but if you ...

None of them will be "right" Strava may throw away your elevation data depending on the device used to record it. So for any phone-based app the height is ignored, and your track is placed on a map, then the known elevation is read off that. For devices with known-good barometric sensors (Garmins and some others) the data in the upload IS used by strava....

A new product, SpyBike, is out on the market and it partially negates the claims I made in my previous answer. The website is hideous, but the general idea appears to be: It sits invisibly in your head tube, under your stem cap. You wave a keyfob over it to "activate" it when you leave your bike somewhere. This way, it remains completely disabled and ...

The Edge Touring comes with a preloaded "Garmin Cycle Map". This is based on OpenStreetMap, so you can check the OSM website to see how good coverage is for the areas you are interested in. In general, OSM is rather good for roads in most of Western Europe, and much of the USA. Many areas also have lots of cycle paths and trails mapped. It is often more ...

All of the Garmin/Cateye devices have similar GPS hardware and will take similar amounts of time to get a lock. I don't think upgrading to another device is going to help you there. Your cell phone is faster because it uses A-GPS, which uses the cell tower data stream to download GPS ephemeris and almanac data. I asked a question a while ago about how to ...

As mattnz alluded to it can be notoriously difficult to estimate calories burned, even with a heart rate monitor. As a bit of history, for the longest time it was generally believed that Polar heart rate monitors were the most accurate, because Polar essentially purchased the rights to the best proprietary algorithm available (going by memory, I will need to ...
