The front of the saddle is marked by the white line. A longer seat post on the road bike compensates for longer legs by raising and moving the seat slightly rearward while maintaining a comfortable distance between the pedals and seat for maximum power transfer to the gears.
The difference in frame size shows up in the location of the steering stem. The smaller frame on the right provides a shorter distance between the seat and the steering stem. The handlebars will also be lower on the smaller frame and need to be raised so there is not too much weight on the hands which would cause numbness in the hands. By using a 4″ riser, the handlebars can be moved up and forward to keep the same distance from the pedals and seat. Even though the steering stem is closer to the seat because of the smaller frame size, the handlebars are about the same distance from the seat.
The stock weight of the mountain bike is about 35 pounds and the road bike is 23 pounds. The 12 pounds saved by using a smaller frame would cost a fortune if using a larger frame and lighter materials to achieve the same weight.
There is a lot of emphasis placed on bicycle weight but it doesn’t amount to much on level terrain where the rolling resistance is more important. Good graphene tires on the road bike provide low rolling resistance. I rarely use the large chainring for racing because too high a gear fatigues muscles quicker. The only time I use the large chainring for going downhill. The majority of the time I stay on the middle chainring unless encountering really steep hills in which case I may shift to the small chainring on a long climb and use the smaller derailleur gears to maintain a fast cadence at the same effort.
Paraphrased Aesop’s Fables for the Corona Virus age…
A cowboy saw a groundhog run past.
Quick! The coyotes are going to eat me said the groundhog.
Go hide under my porch. You will be safe there, said the cowboy.
A while later some coyotes came past and asked the cowboy if he had seen the groundhog.
No I haven’t the cowboy said, all the while pointing at the porch where the groundhog was hiding.
The coyotes didn’t know what the cowboy was pointing at and so they left to go find the groundhog.
The groundhog, having seen the coyotes leave, sneaked out of the hut and was about to run off.
Is that how you repay my kindness for saving your life? the cowboy asked.
The groundhog replied, if your actions had been as honest as your tongue I would have thanked you.

A virus living in a corn field was worried it might be killed off if the farmer came out to cut down and harvest the corn, for it would have nothing left to feed on.
The virus heard that the farmer was asking friends and neighbours to harvest the corn.
There is no danger yet, it said.
A week later the farmer was heard asking his family to help him cut down and harvest the corn.
There is still no danger, it said.
Then one day the virus heard the farmer complaining that he would have to harvest the corn by himself because no one else was going to help him.
Now there is danger! I must leave at once, the virus said and was promptly carried away by a bird to another field where it could continue to eat the corn.
(People who accept no responsibility for preventing the Corona Virus from spreading to themselves and others are like the farmer who blames everyone else for spreading the virus. Only when the farmer eliminates the environment that the virus feeds on, is the virus ever in jeopardy of vanishing from the face of the Earth.)
Snow between March 1-4 was not cleared from the Airport Trail pathway. The requirement for the city to clear snow from pathway is to clear snow that falls onto the pathway. Just because there is no report of a snow falling doesn’t mean that wind doesn’t blow snow and cause a snowfall on the pathway. This is typical between snow events, especially the pedestrian overpass on 96 ave ne when deep drifts can form if it gets windy and also near the hotels at 15 st ne. (Road crews also regularly bury the 96 ave pathway near Deerfoot after pathway crews have just finished plowing snow off it.) Some sections of Airport Trail pathway were still bare and clear right next to snowy sections. Other sections still had snow on them prior to March 4th, which at the time, was still light enough that I didn’t need to make a complaint. Then it warmed up and those light drifts turned to ice before the snow from March 4th snow event.
When ice is left on a pathway it becomes much more dangerous when later on more snow falls on it. It is obvious that a significant amount of ice was on the pathway and it couldn’t have come from the snow event on March 4th because there wasn’t enough precipitation to cause that much ice. It certainly wasn’t warm enough to melt the snow at night and then cause ice to form before morning. That was the night when it was very gusty, a 40-65kph tailwind from the west on March 3rd as I remember.
There were also many 311 requests to have these pathways and access to these pathways cleared in February.
Incorrect reporting cited as in these examples. I was told by 311 that closing a request doesn’t necessarily mean any snow removal was done.
Feb 3rd, reported access to pathways blocked by 9 mounds of ice ridges from 19 st ne to 96 ave (35 days ago).
Then 33 days ago the request was closed without any action.
Then 29 days ago only 7 of 9 crossings were cleared after another complaint although crews could see there was a high ice ridge blocking access at 19st ne and airport trail within eye sight of the two crossings that were cleared at the same intersection. So why were two sections cleared and not the 3rd?
Then 28 days ago, the same crossing (which was too high to cycle over) was still blocked by the ice mound so I HAD TO SHOVEL IT because drivers were getting impatient that I had to stop in the intersection in front of them and hoist the bike over the ice ridge! The lights at 19st ne and airport trail change too quickly for bicycles to clear the intersection while the light is still green if there is any delay crossing it. I made this complaint about the lights about a year or two ago.
Then 27 days ago, road crews buried the sidewalk in more snow plowed from 19 st ne. So in this example a snow removal problem existed for more than 8 days.
So you will excuse me if I have doubts about the validity of what was reported and done by Calgary Parks when on one day a pathway crew might clear the snow after several days and the road crews immediately, the next day, plow snow right back where the pathway crews just removed it a day earlier. Oh, and the snow which was plowed onto the sidewalk at 19st ne on the north side of Airport Trail never was removed. It took a while to melt away.
Pathway is supposed to be plowed within 24 hours after a snowfall but after the previous snowfall it took over 2 days before pathway was cleared which allowed time for snow to melt and form ice. Then another winter storm last night covered the ice with more snow. Dillinger 4 studded tires failed to maintain traction.
Had this pathway been plowed with a bicyclesnowplow, this dangerous situation would not have been allowed to develop since snow would have been removed much sooner before it had a chance to form ice. In addition, many Calgary pathways are badly designed like this location and permit snow to melt on banks and flow across pathways like streams.
Calgary City Hall had been informed several years ago about low cost and more efficient technology using bicycles to plow pathways but has done nothing to implement the technology because it doesn’t cost tax payers enough money to bury the city far enough into a recession or buy more votes with taxpayer money. City Hall has been throwing away millions of dollars on expensive and ugly artworks projects rather than being frugal and practical maintaining essential services. Calgary also has a bad habit of depending far too heavily on Chinooks to clear pathways.
Property owners who complained about snow angels removing snow from pathways are paying heavily for overpriced snow removal fees and fines for not clearing pathways soon enough. You can’t teach fools with cash to waste how to use common sense.
