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

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 ...

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 ...

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 ...

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 ...

Try http://www.gpsvisualizer.com. In the parameters set "Add DEM elevation data" to "From best available source". This will replace the recorded elevation with elevation data from a database, which should be more accurate. Edit: Try this other sub-page of the same site to upload your .gpx and then download the fixed .gpx ...

Pain in the ass, and waste of money. As of the last time I checked, you can't track them directly (there'd be no way for you to receive a signal from a battery-operated device 5mi away), so you need to sign up for a recurring monthly service. On top of that, they chew through battery pretty quickly, requiring a recharge every few days. Contrast that 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 ...

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 ...

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 ...

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 ...

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. ...

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 ...

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 it's own battery. So the dynamo changes the internal battery and the battery charges your phone/gps/device. This allows you to change while you are resting, as well as provide added protection against sending ...

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 ...

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 ...

Try gpsbabel (either as commandline tool or via gpsvisualizer). You can find an explanation how to combine files at http://www.gpsbabel.org/htmldoc-development/Advanced_Usage.html

One option would be to use an iPhone. If you use software such as MapMyRide you can integrate it with ANT+ sensors to measure speed, cadence and even heart rate. These sites also have excellent mapping, training review and history functions. Pros: You can use your existing phone rather than needing separate hardware The online version of mapping software ...

Here's one option: http://h1987995.stratoserver.net/magento/supernova-the-plug-ii-plus-usb-dynamolader.html SUPERNOVA The Plug II Plus USB power supply Transforms dynamo AC to exact USB spec. DC 5V, 500 mA E‐Bike compatible for 12‐ 48V DC with optional cable Works with Garmin, Ipod&Iphone 3GS & 4G & 4GS Seems pretty expensive at €159, but ...

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 ...

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 ...

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 ...

Try a handheld gps device with openstreetmaps. I have a Garmin eTrex Vista HCx with a 4GB card and all of streetmap Europe on it. Just dont hit the "search street button", or the poor little processor will go south.

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, ...

Cell phones, usually not. Some applications will attempt to massage the data using elevation information provided from third-parties, but its a crapshoot at best. A dedicated GPS with a barometric altimeter is probably your best bet. I can't really speak to their level of accuracy, but it's certainly better than other practical options. If you just want ...

It is probably worth switching on the device as soon as you start heading home, even if you are inside a building. While it may not acquire a lock inside, the signal might be strong enough to download some of the data the device has to acquire, meaning it locks quicker once you reach clearer skies. It's also worth bearing in mind that acquiring a GPS ...

I've got a friend who had a cellphone stolen. She used the provider's tools to locate the phone down to a suburban address, and went to get it back. The teenager who answered the door knock said there was no such phone there. Her brother called it and they heard it ringing in the background. Some more people turned out of the house and denied her entry. ...

You will obviously be able to get this from your trackpoints, but it can be useful (depending on the frequency of collection of trackpoints) to take speed - directly from your front wheel tacho if possible. This just gives you a higher degree of accuracy. Other nice to haves: accelerometer input - both fore-and-aft, and left-and-right - these can give a ...
