MorningStar Tooling in California makes a machined from billet aluminum lubrication injector for freehubs. With just the axle pulled back half way out of the hub, the Free-Hub Buddy is pushed into the outer end of the freehub. A hole in the center of the FH Buddy serves as the injection point for either oil or grease. Two holes at the bottom of the seated FH Buddy allow the lubricant to flow into the top of the bearing assembly within the freehub body, and forces the old lubricant to exit around the base of the freehub where it can be wiped away. The freehub Buddy comes with two adapters, using no adapter allows many grease tubes to thread directly into the Freehub Buddy. One of the adapters allows aerosol cans to be the source of either lubricants or cleaners. The other adapter lets needle grease guns, (Goose Greaser, Finish Line, Pedros) to be used as the source of lubrication. The alternative to using this tool is the tedious job of taking the many small parts apart and hoping that you can fit the parts under pressure back together again. The FHB-1 model is for Shimano freehubs, the SHB-4 model is for Suntour freehubs made for the 1991 model year to present.

Shimano's only patent on the freehub cassette system, isn't on the shape of the cut-out of the interior of the cogs, it's on how the freehub body, (the ratcheting carrier that the cogs slide on), is fastened to the hub shell. Shimano's uses a steel bolt built on a steel tube, that has a 14mm by 1mm thread pitch. The inner diameter of the bolt is 10.5mm which permits the 10mm diameter rear axle to pass through it. The Shimano steel bolt has a 10mm hex fitting in its interior, so that with the axle removed, a 10mm hex wrench turned counter-clockwise (anti-clockwise) will remove it. The original weighs 13.5 grams. SRP makes an exact replacement of Ti 6Al-4V rod through a bit of complex machining that weighs just 7.5 grams. This will replace the bolt used in the LX, DX, XT, and XTR. It will also replace the bolt used in the RX100, 105SC, and Ultegra freehubs. It will not work in the Dura-Ace hubs because they are of a very early design, and we have said that we believe Shimano has these scheduled for re- engineering in the 1996 model year when this bolt may be compatible. Remember there are several aftermarket hub makers that also use Shimano freehub bodies freely with the Shimano bolt, read about the hub you have to see if this will be useful. $ Price in Catalog
SRP makes hollow Titanium axles as replacements for the steel ones that come commonly in production Shimano or Suntour hubs. The axle used in all Shimano & Suntour front hubs is hollow, with a 9mm outer diameter and a 5.3mm inner diameter with a 100mm length when measured from the outer edge of the lock nut to outer edge of lock nut, (over lock nut dimension). The rear axle used in most Road hubs is hollow, has a 130mm over lock nut dimension, with a 10mm outer diameter and a 5.3mm inner diameter. The axle used in new Mountain hubs at the moment has a 135mm over lock nut dimension, with a 10mm outer diameter and a 5.3 mm inner diameter. The SRP Ti version is an exact replacement for these, with threads cold rolled into the axle.
