Have the same problem with Velocity A23s--I read all the above--and while some mean well--the answer seems to be that some tires are simply not compatible with the rim(as some have mentioned)!! I was riding Conti-Gatorskins-700x23 yesterday--flatted and where normally I can use my hands to put on a tire or take off had to use tire irons for both feats--and ...

Thought I might add some extra comments to those very good and comprehensive examples of the aero v weight scenarios that Robert provided last year. In particular the dynamic scenario of accelerations on flat terrain, which is a little more complex than steady state cycling. Some might think light wheels would accelerate better than heavier aero wheels, ...

I think the A23 rims are just widely incompatible. I just had a wheel built with one, and tried to install Schwalbe Marathon Almotions. Result: punctured tube, two broken tire levers, and a wheel with no tire.

Whenever I get stuck wheelbuilding, I loosen every spoke one turn, walk away and come back in a few hours or the next day. The worst thing you can do is keep doing something that is not providing the results you expect. It is completely possible to overtighten spokes enough that they stretch significantly under the tension. You can even break them with a ...

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 ...

I have done this but the wheel does not sit central in the forks therefore the brake block shimms need to be adjusted to suit

As PeteH commented, possibly a bad headset (could be worn headset or bearings need maintenance or replacement or the bearing may simply have been overtightened) As we ride, small corrections are constantly made, left, right,, left, right... When the handlebars/fork can't turn smoothly, these corrections become exaggerated - too much to the left, then too ...

Different bikes can have different geometry. The head tube (the tube that continues the line of the front forks up to the handlebars) angle has a big effect on how the bike handles. A steeper head tube makes the bike more "twitchy". You can feel like you're all over the place. A bike like this would be a more serious road bike, and if you are used to using ...

Front hubs on mountain bikes and road bikes are all the same width, 100mm (except for some downhill hubs with through-axles). So you could use either type, they would fit in your forks fine. Note nearly all current mountain bike hubs are designed for disc brakes, so include mounts for attaching a rotor. You can still use them on a bike with rim brakes, just ...

This is the brute force method and may be applied if you desperately need a quick fix. E.g. you're in the middle of nowhere, the wheel won't spin at all and it starts raining... You're planning on replacing the wheel completely, but first want to get home. The technique is much like braking a stick with two hands and a knee: 1. Put your bike upside down. 2. ...

Any wobbly wheel with standard spokes can be "trued", so long as there no broken spokes and the rim itself is not bent. It requires the proper size spoke wrench and a "truing stand". For more precise work you would also want a centering gauge, but that's not necessary in simple cases. The "truing stand" can be a fancy $300 affair, an el-cheapo $50 unit, ...

If it barely touches the brake pads, then it is not critical, you should be able to ride the bike for a time before taking it to a shop for truing, specially if you ride it only for commuting on paved roads, However, don't let the problem stay forever, as it wil degrade over time and will get harder to fix. I wouldn't recommend riding a bent wheel on a ...

There is a down side to not fixing the wheel if it is bent enough to rub the brake. The brake will rub slowing you down. The brake will rub wearing out the brake pad. And causing slight wear to the wheel. The wheel will wobble a bit. If on the front you may notice the bars shaking a bit and hard to ride with no hands. The wheel will take some stress. You ...

You are lucky to have V-brakes, because they make repairing the wheel yourself an easy half an hour task. Plus the tool is $2 usually. Spokes pull the rim one way or the other (look at the spokes and their angle from the hub flange to the rim). If you tighten a spoke, it pulls the rim away. So, you 1) tighten your brakes barrel adjuster until they rub ...
