ALLOY WHEELS DEEP DISH : OLD BOAT STEERING WHEEL : 5TH WHEEL RV USED
Alloy Wheels Deep Dish
- Alloy wheels (incorrectly known as rims) are automobile (car, motorcycle and truck) wheels which are made from an alloy of aluminium or magnesium (or sometimes a mixture of both). They are typically lighter for the same strength and provide better heat conduction and improved cosmetic appearance.
- (Alloy Wheel) Car wheels made of aluminium, rather than steel. Main advantages include lighter weight and attractive styling. Mostly chosen for style reasons.
- A generic term used to describe any non-steel road wheel. The most common alloy wheels are cast aluminum. Technically, an alloy is a mixture of two or more metals. These wheels are known for their light weight and strength.
- Deep Dish is a duo of DJs and house-music producers consisting of Iranian-American members Ali "Dubfire" Shirazinia and Sharam Tayebi. Based in Washington, D.C.
- (of a pizza) Baked in a deep dish and having a thick dough base
- Deep Dish is a 2008 romance novel by the American writer Mary Kay Andrews.
- Extreme or thoroughgoing
- (of a pie) Baked in a deep dish to allow for a large filling
- a soft set where the ball is caught, dragged down to chest or even navel level, and then back up before being released; contact lasts long enough for the player to check the ball pressure and read the label; see carry.
My new Mavic R-Sys Wheelset
2008 Mavic R-Sys Wheelset Item: MAV186 Weight: 1355.0g $1,399.99 Mavic is at it once again. They rocked the wheel world with the introduction of the Helium. They did it with the Cosmic. Then they did it again with the Ksyrium. Since the Ksyrium seems to have been taken about as far as it can go, Mavic is introducing the R-Sys. A quick glance proves that something is different about these wheels, and it takes stopping a R-Sys-shod bike to see what's going on. It's the spokes. They're hollow, tubular carbon fiber, not really spokes at all. More like rods. And their beauty is that they work in both tension and compression. By contrast, conventional wire spokes work only in tension. Spokes: Tensioned spokes are what make bike wheels so fascinating. Most spokes, when taken out of a wheel, are flimsy wire gauge that bend easily. Tension up that same flimsy wire and it can be an integral component in an object that can withstand tremendous force. The key to the spokes working is that they are tensioned in harmony with a mess of other spokes; due to vertical or lateral forces a single spoke can lose tension for a moment, but the other spokes in the wheel will counteract with greater tension. Too little tension in a spoke and the wheel won't stay true; too much tension and the wheel will destroy itself. The fewer the spokes in a wheel, the more load each spoke has to take, making tensioning the spokes an ever-finer balance. Rims and hubs also play into this spoke tension equation. Spoke flanges that don't have enough material on the outside of the spoke hole can fail as a result of too much tension (witness Shimano's hub warranty, which excludes radially-laced wheels). And a rim can fail from too much tension as well. Mavic has been playing with spokes for a long time. The Ksyrium has Zicral aluminum spokes instead of traditional stainless steel spokes. The Zicral spoke, combined with the matching nipple are lighter than a steel spoke and brass nipple, 7g compared to 8g. Their new carbon fiber spokes, with nipple, are 5g. And these carbon fiber spokes have an aluminum head bonded to one end and aluminum threads bonded to the other. They call this "Tracomp," meaning the spokes work in both compression and traction. Mavic has also been playing with rim weights for a long time. In a bygone era, they made 280g aluminum rims, but they were tubulars made with the idea that no fewer than 28 spokes (24 if the rider was super light and smooth) would support the rim. As they went to low spoke count wheels, the rim weight went up and the cross sections went deeper. The R-Sys is a new direction for Mavic, with a sub 400g clincher rim and a shallow rim profile. Take a look around the bike market; there are very few sub 400g clincher rims out there, and the few that are sold generally need lots of spokes to stay true. Mavic has been a hub manufacturer for a long time and has experimented with different hub flanges. When they went to a cassette hub, they narrowed the distance between flanges and increased their diameter. When they developed the Helium, they worked out a minimal flange pattern and employed straight-pull spokes. And with the Ksyrium, they evolved ever leaner hub bodies. With the R-Sys, since the carbon fiber spokes don't need as much tension to stay in place, and barely compress at all, the rims the spokes are attached to can be lighter than other clincher rims, and still be plenty strong. And the new hub body is about as minimal as a hub can get. The flanges supporting the carbon fiber spokes can be thinner than with Zicral spokes because the spokes don't need as much tension. Put the rim, spokes, and hub together, and tension the spokes, the result is a tremendously strong wheel. Vertical stiffness with wheels is pretty much a given, but this wheel has incredible lateral stiffness as well. 56 Nm of lateral force before either the front or rear wheels start to laterally deflect, which makes them 30% stiffer than the Ksyrium ES. This stiffness makes this a great wheel for crit riders and big riders. Put a wheel into extreme situations, and the sideways flex that vexes some riders, leading to overworked and eventually broken spokes on some wheels; this will just about totally disappear. The stiffer spokes should also lead to greater efficiency. The less the spokes stretch, or absorb energy from the hub, the more energy will be put into the rim propelling the tire on the ground. This is a great thing for all riders. One thing that might surprise people is that the rear drive side spokes are Zicral, not carbon fiber. Using tubular carbon fiber spokes would have created a wheel with unacceptable dish. Another rear wheel surprise is that Mavic uses an asymmetric rim; the spoke holes are off-center. A number of companies already do this, but it's a first for Big Yellow. They, like the other companies, do it to better balance the tension between the drive and non-drive spokes. Like all
1979 Shorter (Barry Chick) tt
Alan Shorter (Barry Chick) 1979 Serial no. 1479 Purchased as a frameset from Alexander von Tutschek in February 2010 who acquired this from the widow of the original owner about five years ago. Back on the road 21 April 2010. A British time trial frameset from the end of the great classic era of British time trialling exemplified by Alf Engers who was the first to do a 25-mile tt in under 50 minutes in 1976 riding a Shorter frame. My frame was built by the well-known framebuilder Barry Chick who built most of the Shorter tt frames during the 1970s and his name is pantographed on the fork crowns and bb under shell. The outfitting of the frame was inspired by the time trialists’ tradition of being singular “weight weenies’ and whilst I didn’t go for the extensive (excessive?!) drilling out of components (Alf Engers was noted for this), the choicest and lightest components of the late 70s, early 80s were fitted. This resulted in a build-up weight of 18 lbs. Comments posted to the CR List by Norris Lockley, UK On this Specific Frame "I am really pleased to see that the SHORTER 1970s time-trial frame recently auctioned on UK Ebay by Alex on Tutscheks son has found an appreciative new owner in Peter Kohler. The frame really is a masterpiece of understatement..so very typical of Barry Chick's work..Barry was probably among the top half-dozen builders of time-trial frames in the 70s and 80s, and was equally at home with bronze-welded frames as he was with lugged ones. I expected, as probably did Peter, that such an elegant frame would fetch a much higher price My reckoning on the low price and the paultry number of bids is that very few potential buyers an bidders knew very much about Barry Chick...and that they probably found the name CHICK engraved on both the bracket shell and the fork crown somewhat offputting. The frame is an absolute CLASSIC.
