I have a great idea for a science project.  As posted on Facebook, and reposted here for those who don't use Facebook (who doesnt use Facebook? - the smart people) - I recently learned from Neile that those gray grids at certain intersections are sensors for traffic lights.  See link below for more info.  Shared it in case others didn't know about the sensors.  But after learning how they worked, it piqued my curiosity.  They are electromagnetic loops that are triggered by a disruption (they are not scales).  Cars that cross the lines will cause the disruption, but bikes and in certain instances motorcycles are not sizable enough.  I think the disruption may be driven from steel in the car.

For those of you who wanted to participate in the C SIG either this year or in prior years, we’re offering relaxed and supportive coaching rides every Saturday for six weeks beginning on April 10. If you did graduate the C-SIG but feel you would benefit from additional instruction, we would ask that you wait until the Friday before the ride to sign up to give new riders priority. Please check out our first ride listing on the club website for more information.

Since we sign up for rides 10 days  ahead of the ride, what time of day should we be 

looking for the ride to post?  I've checked in the morning sometimes, and the ride is not open, then again in the 

evening and the same ride is full.  It's hard to check every ten minutes when you work full time, but is that what it

takes?

I read somewhere that our Hudson River Greenway is the most crowded bike path in America. At times I would think it might be so, but in the dead of winter not. Traffic is picking back up these past few days, and with it new challenges to make it home safely. The number of motor-driven bikes, scooters and unicycles are up. I sense that their average speed is up as well. 

Which brings us to a new challenge. When all users had the same limitations of neuromuscular power, relative speed on the Greenway stayed within a certain range. Yes, I am amazed at how fast a young, strong and dedicated cyclist on a road bike can go when I am lumbering along well past my sell by date, but motors make it a whole different ballgame.

These are dual pedals, so I assume power readings are for right and left feet so you can ...adjust your training....  Not cheap at over $1K.  I have 2 bikes.  Can I simply put one pedal on each, so I always have power readings?  Maybe it will be a bit uneven/unbalanced with my right foot readings on my road bike and my left (weaker?) on the tri bike?  But it's cheaper than spending 2K, or buying 2 one-sided sets?

Opinions?

I live in Riverdale. These two shops seem like the best candidates to be my new LBS. They both seem friendly, well-stocked and well-equipped.

However, I've only been in there for minor things, like flats and Gu. Can anybody comment on how reliable they are on major projects, which for me would be a full tune-up, brake repairs, new gears, adjusting my electronic shifting,...?  Thanks.

I'm a B-SIG 17 grad, filled in as a leader in 2019's B-SIG, have done the climbathon twice with the great R. Rosenthal and have done four multi-day rides in Israel.

I've been riding and leading a variety of hilly rides on Long Island that feature what I'd call "short, punchy climbs". 45-60 miles with 55-70 feet per mile of climbing.

Thanks to advice from a prior post I will be replacing a tire that got a nail through the sidewall.  My prior tires were Continental 4000 (700 x 25c) and I was very happy with them. There was a big difference in roll resistance from my prior tires when I first switched to the 4000 a while back.  I believe I was running the Conti gators prior.  Felt like a whole new bike and ride.  4000 are now discontinued and can only find the 5000 on the market. The issue is they run smaller than the 4000 so a 25 is smaller than the typical 25.  I'm thinking of ordering up a size to 28 for this reason and wondering if others have any experience with the tires that they can share.

I got a bad flat the other day that involved a nail going through the tire and sidewall.  I fixed the inner tube flat, but now I'm wondering if I need a new outer tire.  The tire is fairly new and would not otherwise need to be changed, but due to the sidewall puncture wondering if others have recommendation of absolute fails that should prompt a change.  I'm planning on patching the  tires themselves (inside of the tire, but not the inner tube).  Alternatively, I've seen tire liners on sale.  Has anyone had experience with those?  The side wall puncture is right at the rim thread of the tire, where the tire hooks on to the rim.  There is  some torn fibers, but does not look too bad
