Jim’s Tech Talk
By Jim Langley
To start, thanks everyone for the helpful responses on lowering road and gravel bike gearing, which our last Tech Talk was about. It’s an important topic for all cyclists from beginners to experts and not only because our needs change over time. If you missed it, the story and excellent feedback can be found here: https://www.roadbikerider.com/lower-gearing-gravel-bike/.
Two Comments of Note
This week, I want to follow up because a couple of comments surprised me. That’s fine, I can handle it. What concerns me though is that there are plenty of people just getting into cycling who read RoadBikeRider and I’d like to ensure they get the best information. So to that end I’m going to quickly reply to one very short off-topic comment and then tell a story to answer the other one on gearing.
The Off-topic Short Comment
Bike Fitness Coaching said:
What’s more important than this topic is to get the correct crank lengths for your inseam length.
I agree with BFC that if you feel like your pedaling efficiency is off you should make sure you are on the right length. However, if you’re struggling to get up hills, get the right gearing first because that’ll make the biggest difference.
The Comment on Gearing
So if you need to go into ‘overdrive’ gearing, then why go up these hills at all, so you can say that you’ve ‘accomplished’ something?? (30×34 is ridiculous) I felt like a wimp doing the Zoncolan and Mortirolo (steady 18 to 24%) with a compact front (50/34) and 27 in the rear.. In the past, there was no such thing and all riders huffed up the climbs with 53/39 and 11/23 or 25 at most.. You can always create a gearing that will let you pedal 100 revs while going 2 km/hr but what’s the point?? Get an electric bike if it’s for the view at the top.
Several of you already dropped great comments rebutting BigBorb’s assertions last week. I will only add that it’s not true that “in the past there was no such thing.” Smaller chainrings and larger cogs have been around forever and while professional racers may not have used them, plenty of other cyclists did. And today, Tadej Pogacar who just won the Tour of Flanders pedals a Colnago with a 40/50 crankset and an 11-30 cassette. So even the best of the best have gone to lower gearing.
A Gearing Story
In New Hampshire one of the toughest hillclimb races in the country takes place. It’s called the Mt. Washington Auto Road Bicycle Hillclimb (MWARBH). Be sure to click the link to see some great photos.
Quoting from their website “Once a year this race is held on the auto road of Mt Washington…the highest peak in the Northeastern United States. At 6,288 ft, Mt Washington holds the record for the highest wind gust directly measured at the Earth’s surface, 231 mph. The summit features a yearly average temperature of 33.9°F (with no temp over 72°F ever recorded). The route is 7.6 miles in length, has an average grade of 12% with extended sections of 18% and the last 50 yards is an amazing 22%!
Meeting My Twin
In 1978 I lived in New Hampshire and worked in Vermont. I was planning on riding across America so I rode the 25 miles to our bike shop https://www.westhillshop.com/ every day and the 25 miles home at night. I carried my gear on my custom Richard Sachs touring bike in front panniers hanging off a Blackburn rack (in the photo I’m shown with my full cross country setup in Florida – sorry about the photo quality, no iPhone back then).
One day on the way to work I noticed a guy with an almost identical setup as mine riding the other way. I waved and he waved back. This happened the next day and the next. So I hollered at him and he stopped and I went over and introduced myself. His name was Frank Slaughter (I hope I’m not misspelling Frank’s last name).
We Meet Again
I forget where Frank worked and I don’t recall that he was preparing for a cycling goal like I was. But later I ran into him again and it was at Mt. Washington at the start of the race! We were surprised to see each other there. We had removed our racks and bags of course. I had a cycling license and was entered in the Category ¾ event. Frank was in the Novice event, I believe it was his first race.
Infamous Mt. Washington
I don’t know how much the course has changed since that day, but I remember that so much of the surface was hard pack and gravel that traction was an issue. It was so steep too that I stood for mile after mile. I was one of the stronger guys in our category and passed lots of riders.
Near the top the fog was so thick we were riding blind. The race director, concerned about the very real possibility we would ride off a cliff, directed everyone at the top of the mountain to line up along the roadside down the mountain and extend their arms and keep talking to make sure racers knew they were approaching the edge. It was surreal seeing those hands, fingers wiggling and hearing voices urging “stay back, stay back!”
The very top was so steep a support motorcycle stalled out. The driver leapt off as the bike skidded down the hill like a monster hockey puck. Luckily no cyclists were hit and every fan jumped out of the way.
I never saw Frank after the start. His category started after ours so we had a head start. It wasn’t until the results were posted that I saw him back at the bottom of the mountain. We were still in our racing kit with our bikes.
I had my Richard Sachs with race gearing of the time, a Campagnolo 42/52 crankset and a 13-21 Regina freewheel. Looking at Frank’s bike, I saw that he was still running the gearing he had been using to ride to work. I don’t recall what chainring sizes he had on his crankset but I do remember that he had a 13-34 freewheel because back then they looked enormous and I thought to myself how slow it must have been spinning that up Mt. Washington.
So you can imagine my surprise to find out that novice racer Frank spun his way to the top of Mt. Washington IN THE EXACT SAME TIME as Cat 3 Racer Jim lugged his way up on his 42 x 21. Not only that but Frank won the Novice race while I only got third in the Cat 3/4s.
The Possible Moral of This Story
It would be wonderful if Frank reads this story and reaches out to me in a comment or via email. It would be fun to connect again and I’d like to ask him something, not that we can go back and change history.
But, I’d be curious to know if his knees are as destroyed as mine are now? I bet the answer is no.
