Images here [https://imgur.com/a/Q1MTB33](https://imgur.com/a/Q1MTB33) Background. I've been riding bicycles being a kid, and got my first serious road bike in 2016 - Trek Emonda ALR 5 with all Shimano 105s. Lately, I've been doing cycling more frequently with the WFH situation. Because of spending more time on the road, I'd been getting more and more incidents. Several flat tires, chain falling off, chain breaking (not knowing to replace the break pin). Now I always carry a hex set, spare tube, tire pump, patches, and tire change tools. One time shifting front and back at the same time and rear deraileur jammed in the back wheel. But never had a serious fall, and so I considered myself a decent rider. Anyways, about the accident... I was biking in SF with a friend and we were near the Sunset District. We passed by Stern Grove Dog Park and I wanted to check it out, around 5:40 pm now. There was a large downhill road which was curvy. I thought this would be fun to let it rip, and go down fast. See 37.735949, -122.483084 [https://goo.gl/maps/UySBVFPzSZF49LDG7](https://goo.gl/maps/UySBVFPzSZF49LDG7). The hill is quite steep. As I was half way down, \~ 25-30 mph, a speed bump rapidly approached. I didn't see this ahead of time enough, as I didn't notice any speed bump signs, and the bump was only on the right side of the road, hidden behind a curve. My bike was thrown up, causing me to swaying left and right to try and catch my balance. I squeezed both my brakes hard, but as and combined with the swaying motion I lost control and fell on my left shoulder. Must have tumbled several times and landed in a sitting position. I wanted to stand up, but immediately the pain hit me and it was just so painful. Hadn't realized I broke my collar bone yet, just saw all the road rash on my fingers - to the point where the skin was white underneath. I couldn't lift my arm, and felt my shoulder painful. I thought I might have dislocated my arm, and felt bumps in my collar bone. I knew I had broken some bones when feeling my shoulder was jagged. My friend made me get up saying there was a car waiting to go pass and I was in the middle of the road. I stood up to move over to the side and immediately got blurry vision, vertigo, and right and left eye could not keep focus. Feels like my head was spinning, kind of like that feeling when you spin around too much and suddenly stand still. Laid down, was about to pass out from pain, and my friend called ambulance. They arrived relatively quick, 10 minutes or so. I was shivering uncontrollably, may be caused by adrenaline or cold from being on the ground. They put me in a stretcher, taped my head down, and got in the vehicle. I figure it's about 6pm now. The most painful thing I remember was being in the ambulance, and trying not to move my shoulders because of the most terrible pain I've ever felt. Every road bump and turn was torture. I could feel my bones grinding whenever I moved. Feels like holding on dear life. The EMT responder said it was a good thing I wore my helmet because it saved me from a concussion and also probably saved my life. It took about 30 minutes to get to Kaiser Permanente San Francisco. It felt forever. Might be around 6:30pm now. I was put in triage, they took my heart rate and temperature. Probably determined I wasn't that urgent, because it was about 45 minutes of painful waiting and still tied to a hard stretcher and placed on a hospital bed. No field dressing on my hands, no pain medication. About 7:15pm a doctor came by and diagnosed me, asking if I lost consciousness, checking if I had any spinal pains and could feel/wiggle my toes. Then said I probably just have a clavicle fracture (same meaning as broken collarbone) and scheduled me to X-rays. Injected me a pain reliever, which kicked in about 5 min. Put lidocaine jelly on my road rashes to numb the pain. About 7:30 pm I went to get X-rays to my shoulder. And about 8pm the doctor came back and said your clavicle is fractured in 2 places, so you have 3 pieces of bone. Said it would heal naturally without surgery! And the road rashes will heal fine too. Prescribed me bunch of gauze pads and Xeroform soaked pads, change once or twice a day after washing wound with soap and water. And an arm brace to keep my arm and shoulder fixed so the bones can find each other. It would be 4 - 6 weeks for the bones to heal, and 30 days for road rashes. Also said it was good to be wearing a helmet, because it was cracked and fairly damaged. Had a nurse clean and dress my wounds, and I checked out of the hospital around 8:50 pm. As I got home and checked my bike, the frame was bent and beat shifters were beat up pretty bad. I'm glad my head is alright. Looking to get back into cycling again once I heal. Reminder to always wear your helmet! Ideally full gloves and clothing to protect arms and knees from road rashes. When you fall, try to find a nice soft area, and tumble to lose your speed. Also don't be stupid and go fast on a new route you've never done before. Stay safe out there!

A few friends and I planning to ride the mostly non-paved ride from Pittsburg to D.C. late Spring and would like some ideas on what equipment to use. We’ll probably stay at motels/hotels in the nicely spaced out towns. I would like to carry all my stuff with me. I have a Giant Rapid (hybrid bike). Any ideas?

Hey all, Thank for the great posting and intersting bikes on the sub. This sub has been a large part of my increased love for cycling. I got a bunch of questions as I am in the process of purchasing my first NEW road bike. I have been biking my whole life and am currently commuting between 60 and 100 miles a week between going to college and work. Going through the process has been lots of fun and is very informative and insightful. I have settled on a 2019 Giant Contend SL 1 disc. Now on to my questions- * Im looking to possibly do a time trial in October and would like to be prepared and maximize my "free/low cost" gains. I am learning Golden Cheetah and beginning to learn about structured training. I am also learning about the Chung method and aerolab. What are my best bet for in sensors/gps computer? My list currently is * In order of my perceived importance. 1. Bib shorts 2. New saddle(more info below) 3. Aero bars 4. Cycling computer 5. Heart rate band 6. Speed sensor 7. Cadence sensor 8. Power meter 9. different gearing(more info below) 10. Aero helmet * Other suggestions for free/cheap gains? * I am aware that the majority of gains come from positioning but I love fancy/flashy/fast things sometimes * In regards to a computer. I like the price of a lezyne computer but I don’t want to have to have my phone connected to it for gps tracking. I don’t really think I need turn by turn navigation but would like my sensors connected and gps tracked for strava/GC etc. would a garmin 520( great deals on Ebay) work or should I save for a wahoo? * I have a specialized saddle that I got on my last bike that I like better way better than the stock seat. I would still like to get a seat fitted for me though, although its not a immediate need. * I already have spd pedals and shoes so that’s taken care of need, just need to get the positioning dialed in. * I rode a Giant TCR when testing bikes and while I didn’t care for the geometry I liked the 11-28 cassette compared to the 11-34 that comes on the Contend. I am considering swapping to a tighter cassette for the TT but want to keep the 11-34 for the near futuer as the contend will also be my commuter/training bike until I find a beater or I get stronger/ride less hills. (If you want my spreadsheet on gearing that I spent way to much time on it [here](https://docs.google.com/spreadsheets/d/137JN_ZM5r6uyIFpNF4pFFYFC0iX4ZsSDnputiQy09Ck/edit?usp=sharing)) * With training: I am familiar with RPE(rate of perceived exertion) from my power lifting days and have heard a little about its application in cycling training. Can anyone elaborate to how the scale adjusts to biking * I also am already adjusting my diet away from powerlifting and making it cycling focused. Yay for weight loss gains! ​ Sorry if this seems like a brain dump or poorly formatted but this new medicine has been wonderful and now I can focus long enough to do some research and TT/bikes has been the only thing on the mind for the past few weeks. ​ Anything I missed or should consider, please yell at me. ​ Thank you for your time, have a great day and have fun riding!

Hey guys, I bought my first road bike last summer, and right off the bat I invested in some cycling shorts. Now that the weather here is nicer and I can start riding again, I want to take it a bit more seriously, and get the right equipment. However, I'm super new to the whole idea of road bikes (I used a mountain bike for the last 2+ decades), so I want to make sure I'm getting the right stuff. ​ Here are some specs of the bike: 2014 Specialized Dolce EQ Size 51 Tiagra 2x10 Continental Grand Prix 4000ii 700x23 tires 105 pedals ​ I wanted to get shoes (and cleats to go with it), as well as a bike kit with tubes and other essentials. Knock on wood, I haven't had a puncture yet on almost 100 miles, but I want to be prepared. Any and all help is greatly appreciated!!

Hello all, I am in the process of conducting thesis research for my senior industrial design project. In order to reach out to as many people as possible, I have decided to post my survey/questionnaire to multiple different forums. I would appreciate any responses to my research and this will help me greatly with the redesign of my final prototype. You may take this survey multiple times if any of the answers for the first question apply to you. Simply reopen the webpage and click a different answer for the first question to proceed. The link to my survey is below: https://qtrial2019q1az1.qualtrics.com/jfe/form/SV_bOuiLsLWcHww0pn I really appreciate your input! Nik
