The fork is fitted the wrong way around. The brake caliper should be in front of the fork, not behind it. The way it is, the bike will be very, very hard to ride because of the negative rake, making it very nervous. The negative rake is also the reason for the pedal overlap. Normally, you should at most get some toe overlap. Loosen the bolt in the top of ...

Forget the tarp. Ultimately, the greatest danger to your bike is not the weather, it's thieves. As long as you invest in a good lock, practice good locking technique, and don't live in an area full of degenerates you should be fine. My bike is worth more than $1000 and I ride it all over and lock it up outside frequently. When you select your bike, don't ...

Every once in a while it is just bad luck. Most of the time though, if you've fitted a new tube and it starts to leak within minutes, that means you have something on the inside of your tire that is causing the leak. A thorn, piece of glass or debris, etc. Usually you can find the culprit if you very very thoroughly run your fingers along the inside of the ...

In bicycles, the technological advance is not as fast as you might think. This is due to the UCI, which blocks a lot of new technologies or is slow to allow them in races. So I think as long as the older bike is in good shape, there won't be much difference. Maybe it's a nine-speed instead of the modern ten or eleven, but that doesn't really make a ...

The most important thing for a college campus (and commuting in general in places where there are a lot of potentially not nice people) is to have a cheap bike and locking it properly - in particular, one that doesn't attract attention. Old and scuffed up bikes are best for this. I think an old mountain bike or flat bar hybrid (like a 80s/early 90s ...

Astra was the Beacon Cycle house brand, according to Sheldon. As @Blam and @Daniel R Hicks say, it's a mid-range 80s bike (that's a compliment)! The lugs, while nothing special, aren't drainpipe thick - this is a good thing. It was probably built well. Crankset may be Stronglight, and the derailleur and front mech are probably Sachs-Huret. Basic components ...

First, let's answer the first to questions together, as they are closely related. Does one lean with the bike? ...and... Does the bike stay more upright? Short answers are yes and yes in most cases. To elaborate, let's take a look at what you're trying to achieve when cornering. I found this image recently and I think it does a great job of ...

Google 'cyclocross'. The primary difference between a road bike and a CX bike is the size of the tires. You can ride your road bike anywhere your skills will allow. There are some gotcha's though. Skinny tires only have so much traction. Gravel flats won't be an issue for all but the lightest of race tires, but pinch flats from hitting larger rocks at ...

As other answers and comments have indicated, you can successfully ride a road bike on loose gravel. There are five main factors, and they are all interconnected: The depth of the gravel. The key to riding in gravel is smooth lines. Avoid sharp turns: the deeper the gravel, the more your front wheel digs in and accentuates any steering movement you make. ...

If you have n bikes, n+1 bikes is the right amount of bikes to have. ;) Realistically, I think 2 or 3 is adequate - a cyclocross or non-racing road bike can do the first two tasks (road ride + commute) provided it has rack and fender mounts, and one mountain bike is likely good enough for the trails in one's area (if you go somewhere else where another ...

Aside from n+1, the other honest answer is: as many as your spouse will tolerate. I have six (two road bikes, one mtb, two folders, one English cruiser). I have met the spousal tolerance factor. After this, I can only replace, not add. So if I really want that Brompton, one of the folders has to go. Now, your question doesn't also get to another important ...

Check the bike is the right size for you If the bike is still on sale commercially, check what the new price is. You can find out about many brands/models from bikepedia.com Find out what components (gears and brakes) it has and what they'd cost new (by Googling) Check for any hairline cracks in the frame, especially around the head tube, bottom bracket ...

Having a Felt F75 myself, I would recommend the following upgrade path from stock: Clipless pedals They take some getting used to, but behold the extra power and comfort! Tyres (and tubes). Vredestein Fortezza Tricomp or similar lightweight folding tyres will give noticeably better grip than stock equipment. Latex inner tubes will smooth the ride and ...

As one comment has indicated, you may need to evaluate if cold this extreme is even safe to ride in. If you determine that is is, there are several issues you'll need to address. There are a lot of questions here about winter cycling. I went through question with the winter tag. Here are some of the ones applicable to your situation: Breathing may be a ...

First, make sure your bike is fit properly - with a bad fit, your efficiency is likely lousy. More sprockets is not necessarily going to make you go faster/easier - changing gear appropriately and becoming more physically fit will (along with better selected sprockets sizes - we went ages before the Gillette razor-blade increase in rear sprockets...). Most ...

Can I calculate (approximately) how much air pressure is lost by measuring the hose length and diameter? No, you cannot tell how much pressure is lost based on the size of the hose. This is not because there is not enough information to tell but because the hose is irrelevant. You seem to be under the impression that there is some total amount of ...

I won't give my own question the check. I have a few bikes and I see a bike I want and I am going through the can I justify to myself. How many is too much? If you don't have room to store them safely and sheltered then too many. If you are not going to maintain them then it is too many. You can't afford it. When do you need more than one bike? ...

I'm not sure that anyone is going to be able to give you a definitive answer... especially since you are asking if your commute will improve by 30 seconds when the commute time you give has a range of 60 seconds. But 30 seconds out of 17.5 minutes is about a 2-3% improvement, which seems reasonable... The more interesting question would be "what can this ...

Some personal thoughts/opinions: If you're not riding much longer than an hour or so, you might not need much. Perhaps a sports/electrolyte drink that contains sugars will suffice and be convenient. I use mainly cheap gel bars for a sugar hit, but they get quite boring and eat away at your teeth. Flapjack, oats, etc are good for a bit of variety but ...

This will run in python (only 3.X, not 2.7), a free to install programming language. Simply save the following as a file ending .py - e.g. timetrials.py. Then open IDLE3 (start menu), and open the file (Ctrl+O). Finally, press F5 to start it. import datetime from operator import itemgetter def get_int_input(prompt, min_=0, max_=None): """Get a valid ...

Assuming that you're talking about cleats on your shoes, there are three main attachment systems. Left: 2-bolt, Middle: 2 or 3 bolt, Right: 3 bolt. Notice how the one on the left has a chunkier sole. The two-bolt option is used for SPD which are popular with MTB, commuting and touring cyclists. I use 2-bolt SPD shoes on my audax bike because I'm able to ...

Short answer: Height does matter (in fact, there are multiple "heights" which you can find out about in the long answer's links), but there are a ton of other factors (e.g. top tube length which is probably more important). The bike's geometry is what determines how well it works for you. Long answer: What you need is a bike fit (which can be done at most ...

My own personal experience is that small changes can make a big difference, but you should be able to get the bars 1.2 cm higher a lot cheaper than a new frame. I've found that the most critical measurement in a frame is the Effective Top Tube. If that is "right" for you then with enough bodging you can get the handlebars in the right place. For a road ...

Guy Martin is obviously a decent cyclist, but you should note that his record-breaking ride occurred under very special conditions. For starters, he built his own frame (or rather Jason Rourke built it for him). Next, he chose exactly where the run would take place - on sand flats. And not least he was towed in order to get up towards top speed, which ...

I want to use the bicycle for the 26-30mi commute that I do everyday and if it is a racing bike it could potentially save time A trained cyclist can definitely ride farther and faster on a road bike than on a hybrid bike, based solely on wind resistance and bicycle fit. However, the speeds you list are completely unrealistic. Bike speeds are based ...

First, note that frame sizes aren't standard - you may ride a 55cm in one model, but a 52cm in another model (say, comparing road racers to cross bikes). And, you do pick your model based on preference - I prefer a larger bike than most people of my height, since I have relatively long legs and long arms. Most of the time, you can go about 1 frame size ...

If you ride further or faster than you're used to, then some weariness in the legs is normal and should pass within a couple of days. I rode my biggest ride to date a couple of weeks ago and when I got home I nearly lost my balance walking around the house as my legs were a bit weaker than I expected. With a couple of days rest they were back to normal, ...

I had the same problem as you when I bought my rollers, the best advice is to place the rollers in a door frame. Start by holding onto the doorframe and get used to spinning with one hand on the bike. You should always try to maintain a high cadence (and speed) when you first start, the momentum will help you balance. The plan is to pedal in a perfect ...

You probably just have to get used to the geometry of the endurance road bike (since most hybrids are closer to MTB hardtail geometry), which can be helped with bike fit, so the drop bar and saddle are positioned in a way where you can use all the hand positions of the bike (hoods, drops, middle of the bar, sides, etc.) efficiently and comfortably for the ...

Having made this transition myself, you may need to get used to the following things. Gear shifters. The action will be unfamiliar, so you may need to think before a change, so try to change in advance of stops at junctions and avoid shifting whilst out of the saddle. Body position, especially in the drops. It can help to physically train so that your body ...
