comment If I am using Bar End Shifters, is there a compelling reason to change the old brake levers?
The RL520 are for linear pull/v-brakes. They won't work properly with road calipers or cantilevers. There are other similarly prices levers that work with road calipers.

comment Is there a standard equivalent for effort between distance and elevation?
@Rider_X You are correct. The ones I mentioned don't support power meters. Only cadence and HRM. And some other things like temperature that aren't that important in cycling. Whether or not it works for individual riders is up to them. Some people like myself have no intention of ever getting a power meter. So for them, cadence and HRM is enough. Cycling specific units may work better for some riders. Personally, I don't like that you can't display a Map except on the high end Edge units.

comment Is there a standard equivalent for effort between distance and elevation?
@Rider_X Some phones have Ant+ built in, so you may be able to get by with that. Also, there are some alternatives to "bike computers". I have an Garmin Oregon 450 (discontinued), which is very similar to the Garmin Dakota 20. They both support Ant+ and can read cadence and HRM (not speed, although they display speed from GPS). While similarly priced to the Edge 500, the price is a lot easier to justify because the device is a lot more versatile. The Edge series is very focused on cycling whereas the Dakota series is suited to a variety of activities.

comment Fitting a CycloTricity E kit to a Sirrus Elite
I've heard that you should be careful when mounting hub motors to carbon forks because they can apply quite a bit of torque in ways the fork was not designed to handle.

comment Best ways to avoid getting hit by cars?
This goes along with riding fast enough. Try to give yourself room to accelerate. If you are going all out, then the only thing you can do to avoid a collision is stop or turn. If you go at a speed that allows you to accelerate, that gives you an extra way to avoid obstacles. This doesn't only apply to speed, but also to being in the correct gear. Being in the correct gear for your speed can be important in determining whether or not you have the ability to accelerate.

comment Best ways to avoid getting hit by cars?
I have to agree with point 4. But that you should qualify what a respectable fraction of the speed is. Going 15 km/h on a 60 km/h road is probably fine. That's a 1:4 ratio. However, I wouldn't rate the same as going 25 km/h on a 100 km/h road, even though it's the same ratio. Stopping distance does not increase linearly with speed. Try to stay off high speed roads unless they have specific provisions for cyclists such as a large shoulder.

comment Group of Bikes: Is 3x1 an option?
Very much agree with this provided the area is very flat. The Netherlands is notoriously flat. Probably one of the reasons cycling is so popular there in the first place. I would consider my area to be reasonably flat, but I still wouldn't recommend a single speed to most people. Even the smallest bit of hill or a little bit of headwind can make my single speed quite difficult to pedal. I've adapted to it, but most casual cyclists would not enjoy it.

comment Finding better routes than bicycle apps suggest
@Michael - I really think that cycling sites should have very good elevation data for frequently traveled roads by this point. Many GPS units have barometric altimeters built in, and they should be able to get very fine grained detail as to the slope of a road even over short distances. With enough data they could easily figure out what the bad data is. Whether or not they use this data is not known to me, but they really should be using this data. You're right in the fact that satellite or other sources of topographic data are not very accurate.

Good question, but is your 30% value accurate? Most people wouldn't be able to climb a 30% hill, so I understand why they might not consider that route.

comment How to decrease belly fat while cycling?
The self discipline problem can be helped by eating the right stuff. A can of Coke and a bowl of Oatmeal contain the same number of calories, but the bowl of oatmeal won't have you feeling hungry again in half an hour. Try to stay away from high calorie drinks altogether because most people don't actually adjust their food intake when drinking them. If you have a can of Coke with lunch, you should really be eating 140 less calories with your lunch, which most people don't do.

comment Rear derailleur mess up PLEASE HELP. Im helping a 64 year old cancer patient. Very important
Check if there is a bicycle co-op in your city. They often have tools you can borrow for free, or a very small price. If you explain your situation to them, I'm sure they wouldn't mind letting you use the tools for free. Also, they often have people that can help you fix problems. Otherwise, look for free repair clinics put on by community groups. I know there's a few that happen in my city at various times throughout the summer.

comment Bike for college campus
Some campuses are starting to catch on. My Alma Mater has a caged bike area with cameras that logs who goes in and out with a swipe card system. Bicycles are a very economical means of transportation. It's disappointing that the lack of security on campus stops most students from being able to use bicycles.

comment Chain falls to the outside of the chainring, but I can't reproduce the problem
It's actually quite common that you can't reproduce certain problems with the bike on the stand. The should should take the bike out for a test ride or put it on a trainer (might be difficult with a folding bike) in order to get a better idea of what's happening with the bike. The frame flex (especially on folding bikes), and other parts can move in ways which don't happen when there is no load on the components

comment Where can I find the maps my Garmin Edge 305 made?
This says something about .tcx files. Perhaps try doing a search for those. If you used Garmin Training Center it probably used those files. Looks like Strava can support those files directly.

comment '1 1/8' vs '1/2 1/8' chain/chainring
I think the reason for 1/2 inch vs 1 inch is that some manufacturers measure the distance pin to pin, while others measure the length of and entire link which includes the inner and outer plates, and consists of the distance between 2 sets of pins.

comment Mountain bike sizes
@Batman. I think that's why many manufacturers have opted for 27.5 inch wheels on the smaller sizes. OP doesn't say how big he is, so it's kind of hard to answer the question. Even 24 inch kids bikes have an effective top tube of 52.9 and a reach of 37.3. Which is bit bigger than the adult bike I linked to.

comment How can I increase my speed on my hybrid bike?
I agree with the shoes. Not only do they help with power transfer, they make it a lot easier to maintain high cadences, because you don't have to worry about your foot slipping off the pedal. Even if you only have a 44x14 maximum gear, you can still maintain 40 km/h at 100 RPM (as per Sheldon Brown Gear calculator). If you have a 48x12 you could maintain 51 km/h at that cadence.

comment Finding a single speed kit for an old campagnolo from 1997 with screw on freehub
If you are going to end up replacing the free hub, it's probably easier to just replace back wheel with a proper single-speed/fixed hub and then you don't have to worry about using a conversion kit.

comment Is it worth buying a RFLKT+ or is the RFLKT good enough?
@CareyGregory I said I have an altimeter built into my GPS. Also, it's worth mentioning that barometric sensors aren't without their own problems. Since they rely on atmospheric pressure to calculate altitude, weather condtions such as storm can throw them off. A change in pressure of 5 mbar can result in a skewed reading of 40 meters. Even without storms, the pressure can easily change by 1 mbar, resulting in readings being off by 8 meters. They are great in showing change in altitude over a relatively short time, for individual climbs, but probably shouldn't be trusted as always correct.
