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 ...

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 ...

TL:DR Get the CX Bike, you'll love it! You get three bikes in one, without trading in any noticeable performance on the road. This answer is subjective and based on personal experience, you have been warned: I have a CX bike that is used as a do-it-all bike, and I love it. For almost all aspects that concern any non-professional cyclist a CX is as good, or ...

It's doable although it doesn't make sense from a cost perspective. Only do it if you have an emotional investment in the bike or want a fun project that will teach you a lot about bike mechanics. To give you an idea, I bought a 1975 Peugeot UO18 Mixte (a woman's road bike, perhaps similar to your mom's) that had been stored in a barn and turned it into my ...

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 ...

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 ...

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 ...

I'm not sure "designed" is the correct word, evolved comes much closer. Current dual caliper brakes actually stop a lot better than previous single caliper sidepulls. There has always been a compromise between weight and braking power. The designers have focused on how light they can make a brake that stops "enough". I don't think there has been any effort ...

Almost all saddles will be exchangeable -- there are a few rare (and very expensive ones) you wouldn't encounter unless you were looking for them which can't be exchanged. So yes, almost surely if you buy a new saddle you can use it on another bike. Note that some saddles are marketed as "road" or "mtb" - the mtb ones are possibly more durable, but this ...

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 ...

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 ...

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? ...

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 ...

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 ...

These are referring to pad spacers. They essentially increase or decrease the amount of motion you have when moving the brake levers. See page 16 of the following PDF for a better diagram: Shimano Brake Levers User Guide

I currently ride on Rubino Pro Slick tires, and have used various Vittoria tires for decades. The Vittoria Rubino tires you are using have similar wet grip to what I use (dry grip will be the same). The pressures you quote are good. I get the impression that both incidents occurred in the same corner. If that is the case then I would strongly suspect oil ...

Could be as simple as the wheel rubbing on the brakes - rotate the pedals and listen for a scraping noise as the wheel contacts the pads. If this is the case, check that the wheel is true by observing for any wobble side to side as the wheel rotates. If that looks ok your brakes probably need adjusted away from the rims. Start here for brake adjustment ...

Everything is relative. For 99% of the population 30kph for 3 hours would be amazing. For a male A grade club rider it would be an off day. For a female A grade club rider it's not bad for a solo training ride. About bunches Sometimes an ad hoc bunch forms in a popular road. These can be dangerous - you don't know the experience level of these people, ...

Riding at 30kph average for 3 hours, in a hilly area is a solid effort. Assuming your pack riding skills are sufficient, you will also likely do fine in in a club ride that averages 30-40kph (but see the pack riding primer below). Club rides will have a faster pace than what you are riding now, but you will also be working a lot less (about 30% less) at any ...

As already said, aerodynamics are less important to MTB's, but otherwise its largely convention and fashion that dictate what people wear. A vast majority of MTB'r are not wearing basic shorts - they are usually wearing shorts made for riding, including padding just like Lycra road shorts, flat seams and materials designed to withstand the rigour of riding. ...

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 ...

A CX bike is stable, strong, and will take wider tires. It is a great road and commute bicycle. It is built to race in city parks. It has a comfortable riding position. Just put touring tires on it (I like 35mm). I don't mean to advertise a bike but if you look at a high end CX like Moots the even say use as light touring. Rout You are not going to ...

First, note that if you're new to clip/clipless systems, it takes a while to get used to it. A lot of non-racers prefer mountain bike clipless pedals (e.g. Shimano SPD) since you can clip in on both sides of the pedal and the shoes often allow the cleats to be recessed (so you can walk around). Mountain marketed shoes generally tend to be more comfortable ...

For grades beyond 10% having a gear that you can spin at the rate you can climb makes a big difference. Only you can know exactly what gear that should be. If you can find a gear ratio tool that displays speeds for a given gear, wheel size and rpm. This one seems pretty good. http://www.bikecalc.com/cadence_at_speed Then think about your typical speeds ...

The question, mainly, would be, do you feel there is a definite peer pressure around this things? There is undoubtably fashion in a lot of cycling, but there there is in everything. Peer pressure would depend on the group. or a definite selling interest from shops? Yes, but then, that's why they're there. have you ridden with no uniform on ...

One thing to look out for is the size of the drop from the bolt securing the brake to the frame, and the brake blocks, to ensure the new brakes will fit in such a way that the blocks line up with the rims. Probably if you have a newish bike, then any new brakes you buy will be of the same dimension as new brakes. But it's worth making sure they'll fit - ...

Firstly, to answer you question - no, it's not practical for me. Since this is a question of personal safety, no-one can make your decision for you. So in the rest of this answer I will try to set out the issues. It's fair to say that the issue of cycling helmets has been contentious in the past, so I'll give a recap of that. I say in the past because most ...
