comment Fixed gear cranks loosening
I've never had loose crank arms on my fixie. I also don't see how using the pedals to slow you down would have any effect that would cause the crank arms to loosen. Are you sure it's the crank arms that are loosening, or is something else happening such as the rear sprocket becoming loose (because you don't have a lock ring) that's causing the crankset to appear loose? I could see how your crank arms could become loose over time. I don't see how it could be linked to using your pedals to brake.

comment Why is this ring used near the Crankset?
It may be an older bike, or it may be a newer low end bike. I've seen what I thought were antiquated parts on brand new bikes. I think they use parts of older design to make sure they aren't infringing on patents.

comment How to assemble bike chain with no Master link?
I have successfully used a chain tool to get a pin back in after it has been removed from the chain. It's not easy, but yoyo can do it.

comment why does my front suspension have no spring or air valve
The helmet works better if you put it on your head.

comment Legs are very weak
You definitely want to be in the middle or small ring on the front, and stick to the larger gears in the back when climbing.

comment MTB Tyre Safe for Wet Roads
We don't normally do a lot of product recommendations here, but I'm sure some people can help you to look for what features to look for in a tire to meet your needs.

comment How to replace derailleur cable housing?
I've had some luck using my vice grips to cut cables. They have a wire cutter on the inside of the jaw. Make sure you set the vice grips small enough that the cutting edge will fully close. A proper cable cutter as mentioned above will most likely do a better job, but vice grips are probably the next best thing simply because they provide a ridiculous amount of leverage and the fact that they stay clamped on the cable once closed.

comment Should I be able to peel off a glued tire patch?
Personally i find that biggest problem I've had with glue not sticking was due to not giving enough time for the glue to dry before applying the patch, or that the glue has gone bad. Best to try these possibilities before looking for other problems.

comment What is the weight difference between frame sizes?
@Robaggs, The two bikes you own are different models, so I don't think that really applies directly to the question. A frame of the incorrect size could be adjusted using the seat post and stem to fit different sized riders, but that doesn't mean it's ideal. Also, I personally try not to pay attention to what the pros do. What makes sense at that level of competition often doesn't apply to every day riders, even if they race competitively.

comment What does the number 3500 stand for on my Trek bike?
To make things more complicated, some manufacturers will actually use the smaller number on the better bike, for instance, the Scott Sub 30 has better specs than the Scott Sub 20, and the Giant Seek 1 is better than the Seek 2, which is better than the Seek 3.

comment Shimano Sora 3500 (3x9) and Alivio front derailleur
Careful changing the bars from flat to drops. It might mess up the geometry and maneuverability of you bike more than you would expect.

comment Shimano Claris vs 105?
If you go back far enough, Dura-Ace was 6 speed, back in 1982 when it was introduced. The top level pros were making pretty good speed on just 12 gears. I would say that Claris far outperforms what the pros were riding 20 years ago. They didn't introduce 9 speed until 1997.

comment Trailer Lighting Using a Dynamo Hub
Also, you could probably also salvage something from an old kid's bike as it seems to be the same rim size as a 16 inch children's bike. It probably won't be drilled for presta, but you can get grommets to fill the gap.

comment Trailer Lighting Using a Dynamo Hub
Why not use the existing rim and just replace the hub?

comment possible upgrades for merida speeder 200
I'm with @Batman here. something is probably adjusted wrong. It may not even need to be a crash. Simply having your bike fall over on the drive side can be enough to bend the derailleur hanger. Bad cable routing can also cause problems with how well shifting works. Better to diagnose the problem than spend money on parts that won't fix the issue anyway.

comment possible upgrades for merida speeder 200
Thanks for the correction @Batman, I wasn't completely sure on which was compatible. I'll correct it in the answer so there's no confusion for people who don't read the comments.

comment What kind of crankset to get for this bike?
The "pedal wouldn't thread into hole" could easily be because people aren't aware that the left hand pedal is reverse threaded.

comment Is it ethical to ride with races without being part of them?
If you are following the road the cars are on I would say you are fine. If you continue to follow the route after it a has left the road, where the race is taking place, then I would say no. It sounds like you are thinking of yourself as a singular rider who won't really have much of an impact on the race. What if 25, 50, or 100 people showed up and tried to do the same thing? How would you feel if you spent money on race entrance fees, spent time and money training, and showed up early on race day only to have the race ruined by a whole bunch of non-registered people showing up on the course?

Also, if you had an accident with another rider that caused them to get hurt, you might be more likely to be found negligent since you really weren't supposed to be there in the first place.

comment Do I need to replace my rims to move up to a larger width tire?
Yeah, it's important to not confuse 26 x 1-3/8 with 26 x 1.375. They are completely different sizes. According to Sheldon there was even an old 26 x 1.375 that would be incompatible with a modern 26 x 1.375.
