Hill climbing on the Silvio

Rick Newton

Member
I was wondering what are the steepest hills some of the Silvio riders have ridden. My town has a short, but steep section of road from the Strand at the pier into downtown. I have to position myself as far forward at the handlebars in order to keep the front wheel from slipping. I measured the grade with a digital level at 14%. I don't know how low I would be able to hold that position on that steep of a hill, but what a workout!
Has Anybody else out there measured their steep ascents?

I think the record has to go

I think the record has to go to Jim Parker at 24 degrees. My local hills reach 18 degrees on short sections. They are a hard ride if there is sand on the road.

Percent, not degrees.

Hi Drew, I think Jim's climb was 24.7% not 24.7 degrees. 45 degrees is 100%, so 24 degrees would be more like 50%, an impossible climb. Also, Jim rode that hill with a Sofrider and a Quest, not a Silvio. Still, a very impressive climb. Rick, The most I've been able to climb with my Silvio is about 15%, and that was very difficult, with some slipping. I think if I had a lower gear it may be a little easier. I have tried leaning forward to get more weight on the front wheel, but I guess I'm just not coordinate enough, I can't get enough power with my back off the back of the seat to do any climbing. Good luck. Keith

Hi,
   I've made it up some


Hi,

I've made it up some 18% grades (although this 18% grade beat me) on my Sofrider. I find that when I pull myself up with my arms, that I can get more power to the pedals (although in the case of the monster hill, not for very long before I ran out of energy).

Cheers,
Charles

Silvio climbs

Rick,
I've got two steep sections on my regular commute route.
This one : http://veloroutes.org/hillgradecalculator/?loc1=S+Massachusets+St+and+36th+ave+south&loc2=S+Massachusets+St+and+Lake+Washington+Ave+South&units=e
And one to the north of that on Irving street.

The Massachusets one averages 14.8% per that veloroutes site and the Irving one reads 17.0%.
The former is 600 feet while Irving section i ride is only 70 or so feet long.
I can do both of them without wheel slip, but it happens often enough.

I am running 165mm SRAM cranks with a rival compact double and an 11-28 10speed cassette.
When I get the 11-34 (when this one wears out) I should expect to be able to spin up those hills quite easily.
As it stands I am breathing plenty hard at the end of Massachusets.

HTHelps,
Lief

(Cool site for calculating

(Cool site for calculating the grade!)

I find that being able to spin smoothly up the hill makes a big difference as far as traction goes as well. I changed to a triple crank (48-38-28) and that granny gear goes well with the 32 cog I have in the back for the really big hills (or even the medium hills pulling a trailer). So to paraphrase from a local beer commercial:

"Gear responsibly, my friends."

Cheers,
Charles

24%!!

Drew & Keith,
Wow - amazing. That would take a tripple, and that's what I'm using. Thanks for responding too, Lief & Charles.
