|---|
We stock a wide range of chainrings for modern and older crank sets.For more technical detail see the B.C.D. entry in Sheldon Brown's Bicycle Glossary
Any ring on this page will fit any 130 BCD crank, including Shimano Ultegra, 105, Tiagra double and triple, also Dura-Ace double.The middle ring on a Dura-Ace triple is a special "Triplizer" type ring, using a non-standard 92 BCD, for which only one "granny ring", a 30, is made (not available from Harris).
We try to keep all sizes in stock, from 38 to 54 or larger.

These elegant aluminum discs fit any 130 mm crank, a great choice for any deluxe single-chainring bike. For singlespeeds, fixed-gears, bikes with internal gearing, just use one. For single-chainring bikes with rear derailers, use two (special 3-on-1 bolts required.)
These come sized to match 42, 44, 46 or 48 tooth chainrings (specify)
These U.S. made 6061 T6 chainwheels are a great value, and ideal for use for fixed-gear road conversions.
They are thicker and stiffer than most road rings, but they work with either wide or narrow chain.
Double set of mounting holes means they fit either 110 mm or 130 mm bolt circle cranks!They have tall teeth to prevent accidental derailment, and are a great choice for singlespeed or fixed-gear bikes, though they will generally also work with derailers.
These are very similar to the no-longer available Tuf-Neck chainrings.
Available sizes: 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48
These are equipped with shift assist pins and ramps. They're less expensive, because they're steel instead of aluminum, but this is a plus for high-mileage riders, because steel chainrings last MUCH longer than aluminum ones.39 tooth-95 grams; 50 tooth-170 grams; 52 tooth 175 grams.
(For comparison, an Ultegra aluminum 52 weighs 100 grams, less than 3 ounces difference.)
T.A. chainrings are super-high quality, premium rings in Zircal 7075 aluminum. They have machined teeth, and a mirror-like finish.T.A. triple conversion chainrings include the necessary bolts and spacers to attach a 74 mm granny chainring.
Note that T.A. parts are generally in scarce supply, and we can't always keep all sizes in stock. In some cases there may be extensive delays before we will be able to ship. Classic T.A. Cyclotouriste cranks, chainrings and bottomm brackets are listed on our French Cranks Page.
Willow chainrings are 7000 series aluminum, machined in the USA, laser engraved wit the Willow logo, tooth count and BCD. All are anodized and nickel plated (bright silver color) or "Champagne," which is a dichromated plated bright champagne color. These are very nice quality. From RONA components, like Heron frames."Triplizer" chainrings allow you to convert a double to a triple. They have 5 tabs pointing inward, which are drilled for a 74 mm bolt circle "granny" chainring. Willow Triplizers include the hardware to attach the 74 mm granny, but do not include the smaller chainring.
To convert a double to a triple with a Triplizer, you will usually need to replace the bottom bracket spindle with a longer one so the extra chainring will clear your frame.
It is also generally desirable to replace the front derailer with one designed for a full-sized "road" triple.
Note that some older Shimano STI brake/shifter units, including all pre-2001 Dura-Ace and older Ultegra (7- & 8-speed) only work with doubles.
Triplizers will generally work with no problem with down-tube or handlebar end shifters, also with all Campagnolo shifters.
There is a lot of confusion about the compatibility of narrow 9-speed chains with older cranksets. Shimano says you should replace the inner chainring(s) with specially designated 9-speed ones, but then they're all too eager to sell you stuff, whether you need it or not.Shimano is also concerned about clueless users. The worst-case scenario is that you will be riding along with the bike in its highest gear (large front, small rear) and then for some bizarre reason shift down in front before downshifting in the back. (There is no shift pattern in which it is reasonable to shift in this sequence.) If you do shift this way, there's a small chance that the chain might "skate" over the edges of the teeth for maybe half a turn.
In practice this "problem" almost never materializes. Many, many cyclists are using 9-speed chains with older cranksets and having no problems whatever.
