climb grade measurement device(9 posts)

I want to grade some local climbs so I can compare to upcoming races. What is the best device I can use for it? That, and can you fit it in a jersey pocket or do I have to do it while not riding?

Some high zoot cyclocomputers have 'em and, there are also plans for homemade devices (rise over run)... do a Google search. Nth degree (that would fit in your jersey and record the event) would be a solid state device... pricey.

We abide.

Remain In Light.

I kept it on a bike for a couple of months until I'd checked out most of the climbs I do on a regular basis and got a pretty good idea what different grades look like and feel like. It works quite well as long as you make sure the bike is on a level surface when you mount it. And the big kicker - it responds to movement so unless you're a remarkably smooth rider, you need to stop on the hill to get an accurate reading. So it's a bit of a PIA to use. Still, it satisfied my curiosity about a lot of climbs and helped me learn to eyeball climbs after I'd used it.

I just have no idea how steep my local rides are until I can actually ride a hill that I know the grade of and have a comparison point. I might check one of those out.

I use a altimeter cycling computer (Cateye ATA-100). If you know the distance and the rise, the the grade = rise/run

you can trace the roads you'll be riding and then do a x-section plot that lists grade and cumulative climb. you can also parse those climbs into very small sections (yards or less) and look at in minute detail. downside is the maps can be old (some of the newer roads in my area are not there) and I suppose there is some interpolation involved but for 69 bucks it's an easy way of looking at lots of climbs without going out and climbing them all. I use it to plan routes when I'm looking to include a specific amount of altitude gained.

you can also use a Garmin eTrex Vista GPS. it plots "tracks" that include distance and altitude gain. the tracks can be viewed on the GPS or downloaded to a mapping product like the one mentioned above. I've done that with many local rides and have created a nice little comparison database.

Also topographic maps are free at www.topozone.com but the scaling function is not as versatile as Delorme's. Several of the newer bike computers have altimeters and inclinometers.

I have a Ciclosport computer on my bars and it tells me the percent grade, altitude, and virtual power based on total rider/bike weight..speed..% grade...etc.

Try www.ciclosport.de look for the 414 alti $139

I also have the Ciclosport 414. It has told me the grades of climbs around Orlando and Clermont, FL. From the slightest rise at 1% all the way up to 13%. And, it gives you total elevation gained over an entire ride. I did a 53 mile ride last weekend and climbed 2332 feet.

It also gives you power output / watts. So far I have maxed out at 540 watts.
