HarryG's answer was spot on, get a custom wheel built up. However, the trend now is to get a wider rim, yes, wider has proven to be more aero dynamic in wind tunnel tests. The real advantage is that with a wider contact patch, the wheel corners better, has less deflection/deformation and handles better. In fact many riders say that wide clinchers mimic ...

Personally, I ride with a HED Jet 4 on the front and a Jet 5 on the rear. I ride in the Northern California Hills so climbing is a major consideration. I was initially cautious about going so deep because I feared that I would suffer in long sustained climbs. My times climbing were not adversely affected. In fact, I achieved some personal bests in climbing ...

You really ought to be contacting Giant about this, even if for no other reason than to seek clarification of their web page. The link you posted tells you that they are DT Aero Competition bladed stainless steel, and you don't have to look far on the DT Swiss web site to find these exact spokes. What your link doesn't say is the length of the spokes. For ...

From the link you posted, the Giant PSL0s wheelset look like complete DT Swiss wheels, using 240S Straightpull hubs and RR 450 (click "Rims Road") hubs. The DT Swiss site has a spoke calculator at the bottom of the page. If you are a very experienced wheel builder then go for it. If not, get a pro to do it. Asymmetrical wheels are a whole new level up from ...

Are you building this wheel yourself? There's a bit of planning that goes into building a wheel. As Daniel mentioned, length and gauge are important, but even before that you must have a hub that will accommodate the same number of spokes that the wheel will. Afterward, the number of spokes you will need will dictate what lacing pattern you should use. As ...

Generally when new there is room for about half a ball additional in the bearing race, but very quickly wear of the cup makes it look like a ball is missing. And a ball bearing assembly can function reasonably well with 2-3 balls actually missing (though this will cause faster wear). The usual technique, when you don't know for sure if any balls have been ...

To use cartridge bearings, the hubs must have been designed to use them (absurd kludges aside). Your hubs will almost surely be classic cup-and-cone hubs, and those will need replacement bearings. However, do note that the proper number of bearings for a hub is not necessarily a number that completely 'fills' the cup bearing race. You might not be missing ...

If you have a cup-and-cone hub, you need the loose bearings. These are some good directions on doing the replacement. See these links as well for some useful tips.

Really doubt it. 27 is 630 iso and 700 is 622 iso. SheldonBrownTireSizing

These 38/50/60/88 numbers are the 'depth' of the wheel's aerodynamic rim, in millimeters. Let's take 38 for example. This means that from where the tire meets the wheel, the rim extends an additional 38 millimeters towards the hub. When you see 88, that means the rim extends 88 millimeters from the tire. Why does that matter? One of the biggest benefits of ...

Sure, anything is possible, especially if you have access to a oxy-gas welding or bracing torch, a grinder with a cut-off wheel and a willingness to cause mayhem. As a BMX, it'll be heavy and ungainly, especially around corners. When you pedal, it'll pull to one side as it doesn't have a differential, but it'll be tons of fun and something different. Why ...

Since it is a TriCross and will take some pretty large tires it would be nice to keep the option to go to larger diameter so I would not go with a smaller rim. Lots of nice wheelsets out there. An upgraded wheelset does a lot for a bike in my opinion. Do you want to spend $200, $300, $400, ...? There are cyclocoss wheelsets but since you are running ...

a. Clincher and Tubular refer to the type of rim on the wheel, and what type of tire can be used on the wheel. b. Clincher wheels are the most common type and are used with a tire and an inner tube. If you get a flat tire with a clincher, you can change out the inner tube and continue riding fairly quickly. c. Tubular wheels are lighter and cheaper, ...

While riding with broken spokes is possible, I have started to keep a pair of spare spokes taped down low on the seat tube mostly out of view. I typically only seems break spokes on the rear wheel and then on side away from the gears. So it's a quick fix to pull out the broken spoke and thread in a spare. The wheel is far truer that with the broken spoke. ...

Spokes on any wheels can break ... really comes down to how well they are built, the weight they have to carry, i.e., carrying more weight than they are designed for and the type of riding they are exposed to. The Shimano WH-R500 wheels are lower specification wheels and I suspect the Alex ALX-295 are much the same. That said I believe the Shimano wheels ...

You have 27inch wheels, and you can still buy tubes, tires and even new wheels.

I've got the following sorted so far, so here are some answers about the first part of the process for me. Next up will be installing the groupset. Wheels: 27 inch wheels are slightly narrower in width, and greater in rim diameter than the closest modern standard, 700c. In order to fit a modern 700c wheel you will have to worry about two things: The ...

I think it depends on your frame, I have a 1973 Peugeot UO-8 which I replaced the 27inch wheels with 700 28CC and even replaced the handle bars with modern alu bars from MEC. The seat is now a Brooks and because the seat post tubes on french bikes are smaller I had to use a BMX chromoly post. My bottom bracket is a new square one from Velo-Orange instead of ...

Great article about the pros and cons. The writer chose a 28" (700c) bike for single bike, and 26" for the tandem bike. 700c vs 26inch Wheel Size for Touring

I prefer the feel of tubeless tires. Using the same tire, there is less rolling resistance by removing the tube.

Like many comments, it sounds like it's at least partially related to a change in tire pressure. There's also the external change in tire tread that could contribute to the sound change. If you listen to a large knob tire on a road versus a small knob one, they sound totally different. Your tread might be starting to wear, thus giving a different sound. The ...

The protective layer is known as "rim tape". The old tube shouldn't remain within the tire - the only thing inside the rim should be the rim tape and the new tube. You may have different tire pressures than before - have you tried playing with them?

Your problem is more likely to be wheel alignment than anything being too tight. The tops of the dropout (with the bike upright) should be sitting on the axle, but it's easy to get a little gap there if you're not careful. When that happens the wheel doesn't sit quite stright in the fork and it will rub on the disk rotor if you have disks. Plus if you're ...

This is not a problem of a too tight skewer. The skewer should be tight to hold the wheel in place as riding on a loose skewer is dangerous. If the brake does not rub with the skewer loosened then it also won't with the skewer tightened when the wheel was properly seated. You must have tightened the skewer with the wheel not properly seated. To fix it, ...

When you have a multi-speed setup, the derailleur handles all responsibility of maintaining chain tension. The Cross-check frame has the semi-horizontal dropouts so it can be utilized for single speed applications, and it's only for those applications that you control chain tension by wheel spacing. Where the wheel goes in the dropouts for a multi-speed ...
