Bicycling - Shimano Road Bike Parts Compatibility - 2014
The following compatibility chart was provided as part of Shimano Specifications released in Aug. 2014.
Shimano has introduced 11-speed Ultegra groups, both mechanical and Di2 electronic. There is a movement away from compact cranks and toward a rear derailer design with greater capacity to handle low gears. The 6800 (Ultegra) series and 6870 (Ultegra Di2) are announced. Though compatibility charts show no connection between the new FH-9000 or FH-6800 rear freehub and older 10-speed components (cogsets etc.), it has been set up so that 11-speed hubs are reverse compatible, via a 1.85-mm spacer, so your 10-speed cassette can be used with them. Since the 11-speed cassette is wider though, it will not fit on 10-speed hubs. Possible exceptions with some hub manufacturers who have created them with 11-speed in mind.
Next some Shimano products available from our affiliated shop: Amazon (speedy delivery, good selection). The below links take you there.
Shimano R700 (crankset) is the compact version of Ultegra (back in 2008). R600 is the compact version of Shimano 105.
Triple Crank and compatibility: See the 2011 front drivetrain compatibility chart above for some details. The left (front) shifter, the crankset, and both derailers may be specific for a triple gearing. If you have a 105 front brifter, you may be lucky as it's non-indexed so the same brifter can be used with a double or a triple. If yours is Ultegra, there should be a difference so you need the specific front brifter for double or triple whether you're on the 6600 or 6700 series. The front derailer has much different spacing on a triple crankset. And the rear derailer has a long cage to collect more chain - so both of these are specific for triple gearing. Another thing that many people don't realize - the new Shimano chains are *not* triple-compatible. (As indicated on the 2011 compatibility chart), The reason for this is that the new chains (CN-7901, 6701, or 5701) do not allow enough lateral movement. So for the moment, your triple chain needs should be satisfied by KMC, by SRAM, Wippermann maybe, or by the older Shimano chains (CN-7801, CN-6600, CN-5600).
Brake Shoes and Pads R55C3 is the model number for the Shimano branded spare brake pads (2011). It comes in different compounds for alloy (aluminum) and carbon rims. The pad length is 55mm and this pad is compatible with BR-7900, BR-7800, BR-7700, BR-6700, BR-6600, BR-6500, BR-5700, BR-5600, BR-5501, BR-5500, BR-R650, BR-R600, BR-R561 calipers. R55C3 replaces the R55C model which used the same specification but slightly different compounds. Kool Stop has for many years marketed fully compatible replacement pads in a few different compounds. Swiss Stop markets high-performance pads which are also compatible. There are also a few other vendors.
FC5603 crank limitation For compatibility with front derailer FD5603, the FC5603 Shimano 105 crank should use chainrings of 50-39-30 tooth sizes. This is in Shimano charts for Front Drivetrain, 2008 and 2009. This likely indicates a limitation in the front derailer capacity, but I don't know why the Ultegra FD6603, which has capacity for the standard 52-39-30 tooth ringed Ultegra triple crank, would not also support the smaller toothed 105 crankset. There is no compatibility shown for this combination in any of the charts.
Rear derailer capacity limits For Details, see derailer capacity table. Shimano charts provide for an exception to the compatibility rules between cassette sprockets and rear derailers. Specifically, only the 7900-, 6700-, and 5700- series rear derailers have sufficient capacity to support a cassette with sprockets differing as much as 16 teeth or more from small to large cog. For this reason, the 11-28 tooth cogset (17 tooth difference), available in 7900-, 6700-, and 5700- series is not compatible with the older series rear derailers. The 11-27 tooth cogset has the same limitation. For the older 10-speed derailers (7800-, 6600-, and 5600-series), the maximum cogset tooth size difference supported is up to 15 teeth (as in the 12-27 size). In the 2012 and 2013 model years, the available products and their limits have seen some additions and special cases. These details are being tracked in the derailer capacity table.

Junior sprockets with 13 or more toothed top gear
A difference exists in cassette sprockets labeled CS-6600 which are for "junior gearing". Do not use the "junior gearing" CS-6600 sprockets with normal freehubs - they do not fit. Junior gearing CS-6600 sprockets can be identified as having a top gear of 13, 14, 15, or 16 teeth. The normal size sprockets, which are compatible with all normal freehubs, can be identified as having a top gear of 12 or 11 teeth.
Part Naming Color Codes Shimano parts such as FC-6601 may have a 1-letter suffix, for example FC-6601-G. This letter is a color indicator and for the purposes of compatibility, this letter is ignored. The monkey can sleep easier without it, knowing the color does not affect compatibility in any part combination. Use the charts and the monkey without the color suffix. Other suffixes were for example, RD-5600-S (silver), ST-5600-L (black), where the FC-6601-G is gray. Parts with no suffix are silver, as is the suffix S, only used when there is another color option for the same part.

Shimano 105 Triple Shifter Change
The 9-speed 105 front (left) shifter (model ST-5500 or ST-5510) is compatible with both a double or a triple crank configuration. Shimano's move to 10-speed cogsets initially started out like this: the 105 front shifter (left, ST-5600) was compatible with both a double or a triple crank configuration. But Shimano saw a large number of warranty claims due to breakage of the shifters caused by improper setup early on. Their response was to introduce the double-only compatible ST-5601 and the triple-only ST-5603. Ultegra and Dura-Ace already had the double-only and triple-only shifters.
Rear Derailer Naming and Charts The Shimano charts leave off mention of triple rear derailers, but there are important distinctions to be aware of. For the monkey and these note pages, we use the standard "03" naming convention for triple rear derailers. There are actual several possible naming conventions for rear derailers, and it is important to distinguish them. The triple-compatible rear derailers, designated on this site as RD-6603 and other IDs ending in "03", have a longer cage to be able to take up more chain, as triples run longer chains than doubles. In other places, these triple rear derailers are designated "GS" as in "RD-6600-GS". These are the same thing. One other description you will hear is "long cage" or "medium cage" to refer to road triples. On a road bike, it's considered long since it's longer than a short-cage RD used for doubles. But since there exist even longer cages (on MTBs for example), the road triple RDs are also called "medium cage" sometimes. Double Derailers: These are designated here as ending in "00" or "01". Other places use "RD-6600-SS" and other IDs suffixed with "SS", or possibly "RD-6600" short cage. There is little difference in functionality among RDs, so the Monkey learned to assume compatibility with respect to triple RDs as parallel to double RDs.
Tip: for triple rear derailers, look for "GS" or "long cage" (sometimes aka "medium cage") or the "03" or "04" numbers. For double rear derailers, look for "SS" or "short cage" or the "00" or "01" numbers.
