I am not a doctor, but its sound like you might be suffering Post Traumatic Stress, and should seek professional help to rule it out or get treatment. You should be concerned about the 10 critical accidents (I read critical that as hospital/doctors visits and time off school/work, not a mere "off" ). You are likely riding beyond you limits, and need to ...

The most comprehensive guide on bottom brackets online I know of is here. You can replace the square taper bottom bracket with a Hollowtech II bottom bracket and use a compatible crankset with that bottom bracket. The particular crank you choose should be such that your derailleurs are able to handle it.

The new bottom bracket will fit as long as it is of the same thread and type. The Trek uses an English thread bearing. Shimano also says that you must use a mountain bottom bracket with a mountain crank. The new crank must be pretty close to the same tooth count as the original. The front derailleur is designed to work with a limited range of ring gears. If ...

I think that with a well-running bike you ought to be able to do three things: The wheels ought to spin -- life each wheel in turn off the ground and set it spinning with your hand: it ought to spin and spin and spin almost without ever slowing down, almost frictionless The tires shouldn't absorb energy -- that means you don't want knobbly tires because ...

Given that the Schwinn sidewinder is a Walmart bike, you're best off getting a new bike. We call these BSO's or bike shaped objects. By the time you get a basic suspension fork, you'll be spending more than the bike after installation, whereas you could easily buy a good used entry level front suspension mountain bike (say, a Specialized Hard Rock or Trek ...

First of all, make sure you really have a 1 1/8" fork. Most threaded forks are 1". Remove the top nut on the headset, and measure the outside of the steering tube with vernier calipers - that's the dimension you're interested in. If it is 1 1/8", then yes, absolutely, you can install a threadless fork. You'll need a new headset and new stem. You can re-use ...

Yes, you can use a 1 1/8" fork with a 1 1/2" frame. I did it on one of my bikes. You just have to get a special "reducer" headset. It doesn't look goofy at all - you can't even tell unless you look closely. You'll have to get a threadless fork. Nobody makes reducer headsets for threaded forks. Most new forks come with an un-cut steering tube - that means ...

At a minimum lube the chain and see what is scraping. For the brakes just hold the bike up with one hand and spin the tire. Visually inspect if the rim is rubbing on the brake. Some times you can just adjust the brake and some times the wheel(s) need to be trued. Some times you have the tire rubbing on the brake. At this point need to decide if it is ...

Since it's a new-to-you secondhand bike, for safety's sake as well as to deal with the sluggishness I recommend you take it to a bike shop for a complete overhaul. I'll bet you'll be astounded at the difference when they're done.

First thing you can try is to disassemble and grease the bearings with the proper stuff. To do that you have to do the following: 1) Disassemble them as unscrewing the cones' contra nut and the cones themselves. 2) Wipe the old grease with something ( I am doing it with toilet paper ) 3) Wipe every individual ball of the hub. 4) After everything is clean, ...

I think a more practical solution to your problem of forgetting to lock your bike would be a device (or method) to remind you to lock it. You could try a bluetooth proximity alarm tag. You pair the tag with your phone, then attach the tag to your bike. When the phone gets out of range of the tag an alarm goes off on the phone (range is typically around 10 ...

There are locks that can be unlocked with your cell phone, but none of them lock your bike automatically. I'm pretty sure the product you are looking for doesn't exist. The reason this doesn't exist is because it wouldn't be possible. You could build a lock that would automatically lock the wheels based on a proximity detector linked to your cell phone. ...

This answer will probably garner a lot of downvotes, but I'll say the best lock is no lock at all. I haven't used a bike lock in years. I don't ever leave my bikes somewhere that I feel the need to have them locked. My bikes are secured in my domicile, in a similar situation at work, and anywhere else they don't leave my sight. There are many different ...

This "attack position" is not what you would call attack in road cycling. What they mean here is the base from which you start the technical section on a mountain bike trail ( MTB technique is generally what the entire book is about). The terminology in this book is sometimes quite bizarre and many of the terms are not usually used in MTB jargon. This ...

If you've already checked the lower limit screw of the derailleur, and also checked for a bent derailleur hanger, another thing to consider is cable friction. To get to the smallest cog, the derailleur spring has to move the derailleur all the way to the outside. While it's doing that, the spring is pulling the shifter cable out of its housing. If there is ...

Assuming your derailleur isn't bent, you need to adjust the derailleur. If the derailleur is bent, you will need to unbend it. Your shifters may not be catching the last gear as well, but you'd probably feel that when you tried to shift it up. The frame has nothing to do with it.

The position does change from one discipline to another. There are no fixed values or ratios, but, at least until recently the differences were significant. In the early day of mountain biking racing cross country was a long race (almost 3 hours) with few technical sections. Since these races were flatter, it was thought that aerodynamics could play a ...

If your landing is soft you should put some old carpet over it. This solution is not as good as having a completely packed landing and it's still soft (therefore more rolling resistance), but you can carry a lot more speed once you have landed. An added bonus of using carpet is that the soft landing will not be damaged as much by you landing on it.

You could probably rent a Wacker ( yes, that is the real name ) at a local construction equipment rental store. It is a tool that ground construction workers use. It is basically a really heavy steel plate that an engine sits on. The engine vibrates the whole machine and the weight and the vibration compact the ground very tightly. You'd have to work in ...

I've raced several Super D events on an aggressive hardtail and did just fine. I'm usually middle of the road on my time, of course these are not pro races. I'm doing several more Super D and Enduro races this spring and summer, I say have a blast on the hardtail!!!

If you mean 12mm thru axles, they have been around for a few years now but in different guises depending on hub and frame spacing standards. • 150x12mm • 142x12mm • 135x12mm With the rise of enduro/am/do it all style mtb It's about creating harmony between weight, stiffness and ease of use. and a standard going forward that can adhere to modern frame and ...

I have done couple of 300's and learn something that maybe useful: 2 (or 3 is better) spare tubes. Multi-tool. Powerbank to charge mobile. Gloves. Pre check weather and carry rainwear. Spare batteries for head/tail lights.

Typically, a chain uses a grease lubricant which is applied hot to the chain into every crevase of the chain before the chain is assembled. Its generally the best lube you can get on a chain, but its impossible to apply at home in the same way (contrary to sheldon brown) [aside from the fact that that particular formula is likely not sold]. Some more details ...

Normally there would be a fairly strong spring that would be pushing the front derailleur towards the smallest chainring (easier gear). You mentioned that you have already attempted to set the limit screw that determines how far the front derailleur can move towards the smallest chainring. If you have done this correctly, and it still doesn't move far ...
