SLC to Provo Areas in Utah The buses in this area generally have front-mounted bike racks, very similar to those pictured in other posts. They can handle 2 or 3 bikes. If the rack is full, a driver of an underloaded may allow a bike onto the bus, but this is at their discretion. The larger trains (FrontRunner) generally have a bike-specific car. Riders ...

Due to Covid I have to measure my body temperature when I enter the office. Since I happen to bike to work, I was concerned my temperature would be measured to be "hot". Well, it turned out that in the morning, even though I am sweaty from a 40 minutes ride, my forehead barely reaches 29 Celsius, regardless if I am cycling bare head or wearing a ...

The body controls its core temperature, not the skin temperature. Skin temperatures will vary significantly, to the point they are generally considered an unreliable way to measure core temperature, especially for people under heat stress (Riding a bicycle). (Refer : here) Screening using such a thermometer is more about the "Security theater" of ...

One factor could be the lower emissivity of sweat compared to human skin. At a given temperature, different materials emit different amounts of infrared radiation for the thermometer to detect. Skin has an emissivity of about 0.97. (1.0 is the maximum possible value). At the same temperature, pure water will emit slightly less because it has 0.96 emissivity. ...

Lowering the hand position will essentially move your shoulders forward and down, in an arc. This will put your head further forward, and you'll have to look up slightly more. It will also put more weight on your hands. If you currently ride with your elbows slightly bent, then they will end up straighter. This will also very slightly rotate your pelvis ...

It is a very poor design: the seatstay does not intersect the rear axle but rather strikes the dropout about 2 inches behind the axle. This creates a rotational force on the dropout. The reason it always happens there is that the dropout/chainstay joint on the non-disc side has the most leverage. On the disc side the dropout extends much farther down the ...

The 7700 is higher quality when new than a new Claris derailleur . In particular jockey wheels are sealed bearing and more durable than those on cheap r/ds sold today. http://www.disraeligears.co.uk/Site/Shimano_Dura-Ace_derailleur_7700_GS.html A new rd might be better than a worn out old one with worn out jockey wheels (which you can replace), but ...

7700 was a 9-speed groupset. at that time, the cable-pull ratio was standardized, such that any 6- to 9-speed shifter, including your Claris, should work perfectly. If your shifting is only "so-so," I might look for alternative explanations. so, as far as performance is concerned, they should both work equally well. it's hard to even say what would ...
