UNO ASA-105 Stem (31.8)

uno steel
UNO ASA-105 100mm

This 100mm stem weighs only 107g, saving up to 53g over an OEM stem. They are made by Kalloy, a major OEM supplier of components like stems, seatposts and bars. Fit and finish are good, they meet CEN standards. UNO is their own house brand, but you can also find these rebranded for much more money. Comes in a wide variety of lengths 80-130mm, in both 7° and 17° versions. While not the best value if replacing purely for weight reduction, if you need to change stems for fitting purposes, you will most likely end up paying more for a heavier stem buying anything else. They come with different logos depending on year. There is another version of the stem that looks almost identical, but is slightly heavier and made from 6061, the ASA-025. At $21, and saving 2.5g per dollar, it represents a good value, moderate cost upgrade. They can be found on eBay. If you can’t wait for overseas shipping you can pay a premium for a similar OS stem made by Kalloy from Nashbar or Performance Bike.

Forte Pro Lite

Forte Pro Lite

A Forte Pro Lite weighs only 189g, saving up to 141 grams over an OEM wire bead tire, or 282g worth of rotating mass for a pair. The Forte Pro+ is significantly heavier and less supple. 23mm wide, and with a 120 TPI casing, these have the almost paper-thin supple sidewalls you would expect from a high quality high TPI racing tire and come in lighter than the advertised 205g. I’m not sure they have any flat protection though. At $19 each, and saving 7.4g per dollar, it represents a exceptional value, moderate cost upgrade. They can be purchased from Performance Bike.

They seem to be on clearance, being replaced by the new Forte LCR tire. They may also not have any flat protection.

Rubino Pro Slick 25mm

Rubino Pro Slick 25mm

A Rubino Pro Slick 25mm weighs only 239g, saving up to 91 grams over an OEM wire bead tire, or 182g worth of rotating mass for a pair. Vittoria advertises them optimistically at 225g. These are the Pro Slick version, the non-pro version not only has a heavy wire bead, but also a lower TPI casing. Although advertised as a 150 TPI tire, the sidewalls feel thicker than you would expect, although they are still very soft. It may have to do with the way they apply rubber. They make a good all-round tire. The 25mm version is not as wide as expected, and does not seem to be a full 2mm wider than the 23mm version. At $20 each, and saving 4.6g per dollar, it represents a excellent value, moderate cost upgrade. They can be purchased from one of the various UK based webshops.

Heavier than advertised, and not as supple as the TPI would imply. Not a full size wider than the 23mm version. Still a good all-round economical tire.

Rubino Pro Slick 23mm

Rubino Pro Slick 23mm

A Rubino Pro Slick 23mm weighs only 225g, saving up to 105 grams over an OEM wire bead tire, or 210g worth of rotating mass for a pair. Vittoria advertises them a bit optimistically at 215g. These are the Pro Slick version, the non-pro version not only has a heavy wire bead, but also a lower TPI casing. Although advertised as a 150 TPI tire, the sidewalls feel thicker than you would expect, although they are still very soft. It may have to do with the way they apply rubber. They make a good all-round tire. The 23mm version however, appears to have some molding defects, with a very distinct seam on only one side of the center strip. At $20 each, and saving 5.3g per dollar, it represents a exceptional value, moderate cost upgrade. They can be purchased from one of the various UK based webshops.

Heavier than advertised, and not as supple as the TPI would imply. The batch of 23mm which this came from seemed to have a minor molding defect. Still a good all-round economical tire.

Veloplugs

This rim-strip alternative weighs 7g for 44 pieces, saving up to 31 grams over rim tape. Velocity, the makers of Veloplugs, touts many advantages to Veloplugs including extreme blowout strength, easier tire mounting and easy spoke access. Obviously these aren’t for tubeless. They come in two sizes, red and yellow, which fit different size holes, and may or may not fit your rims. If the fit is particularly loose, it’s not unheard of to drop a veloplug while changing a tube. However, when they work they are great, the issue with Veloplugs are mostly compatibility issues. You get 72 in a set. At $12 saving 2.6g per dollar, it represents an good value, moderate cost upgrade. They can be purchased online or through your LBS.

Wellgo MG-8 SPD

mg8
Wellgo MG-8

These pedals weigh only 242g for a pair, saving up to 122 grams over Shimano PD-M520. The pedals are significantly lighter than the entry level Shimano PD-M520 which are often used as first clipless pedals, or any Shimano SPD pedals for that matter. However, they are single sided, require some practice and are not as easy to use as double sided SPD pedals. They also use an inboard bushing like many cheaper or lighter pedals, and will eventually wear out, but being made by Wellgo, are otherwise completely functional pedals. The sources for these pedals at low cost are drying up. You can get an ugly painted version from Pricepoint for $30, but they are otherwise $45 on eBay. Aawyeah seems to have recently sold out. At $30 saving 4.1g per dollar, it represents an excellent value, high cost upgrade. It can be purchased on Pricepoint and eBay, and formerly Aawyeah.

Some may find single sided pedals awkward, and the bushing will eventually wear out, especially if you don’t maintain them. Supplies seem to be limited. At $45, they’re only a good value.

 

Fairing Bolts (Button Head)

fairing bolt2
Aluminum M5 Fairing Bolts (5pc)

The fairing bolts weigh only 4g for a set of 5, saving up to 13 grams over a steel bolts. These bolts are sold as fairing bolts for motorcycles, and come in a variety of colors. Normally, bolt tuning is considered being a drastic measure for every last gram. While bicycles do not have fairings, they use several M5 bolts. 4 for the bottle cages, and 1 for the bottom bracket guide. Some people also use them for the front derailer, but these aren’t long enough for a chain catcher. Note that the bolt may have to be cut short to not interfere with the bottom bracket. If you can not cut metal, you can keep the steel bolt, or use an inexpensive even lighter nylon M5 or 8-32 screw, as it requires very little strength. While I doubt anyone cares about saving 10g off of a 500lb motorcycle, these are anodized in various colors and made in aluminum for that reason. These are lighter than the other style of fairing bolt, longer, and have a lower profile head. Their disadvantage is that they use a smaller M3 hex key instead of M4, and tolerances are not as good. At $2 for a set of 6 saving 6.5g per dollar, it represents an exceptional value, very low cost upgrade. It can be purchased on eBay.
