Derailleur-Front The front derailleur is the mechanism that shifts your chain from chainring to chainring. Front derailleurs typically malfunction because (A) the derailleur body is not positioned properly, (B) the derailleur limit screws are not adjusted correctly, (C) the mechanism is dirty or (D) the cable is damaged or improperly tensioned. The derailleur "cage" (the long, curved section of the derailleur that the chain passes through) should be approximately 2mm above the teeth of the chainring (when viewed from the side). www.khurramweb.com /cycling_articles/title/Derailleur_Front.html   (1238 words)

derailleur If your derailleur was recently installed or if you know that you took a direct impact to your front derailleur, then the first thing you should check is the air gap between the big chainring and the bottom of the front derailleur. Put the chain on the front small chainring and on the smallest rear cog.  Rotate your pedals and shift your front derailleur to the large chainring watching that the chain should jump up onto the large chainring without overshooting it.  If the chain is overshooting the large chainring, then , shift the front derailleur to the small chainring and the rear derailleur to the largest cog.  Stand behind the bike and eyeball the alignment.  The derailleur cogs should be in line with the smallest cog.  If not, adjust the L screw so that it is in line. www.garynuke.homestead.com /derailleur.html   (394 words)

www.cyclingnews.com news and analysis The basic adjustments for the front derailleur are the height, rotation, limit screws and inner wire tension (index setting). The front derailleur cage should be approximately parallel to the chain. Generally, the outer cage of the front derailleur should be aligned to the chain. www.cyclingnews.com /clickthru.php3?url=/tech/fix/?id=frontmech   (2091 words)

How to Adjust a Front Derailleur Use a 5mm Allen wrench and loosen the bolt holding the cable on the front derailleur. Push the old cable out and then thread the new cable through the shifter, through the stays and down into the derailleur It is recommended that if you are going through the effort to replace the cable you should replace the housing at the same time. The chain should have approximately 1mm clearance between the chain and the inside plate of the derailleur Back out the inside screw on top of the derailleur to move the unit inward, towards bottom bracket. www.totalbike.com /service/frontderailleur.html   (304 words)

The Cycle Workshop from e-cobr   (Site not responding. Last check: 2007-10-22) The front derailleur is the metal "cage" attached or clamped to your seat post that moves your chain from one chain ring to another. If your front derailleur is properly adjusted, the chain will shift quickly and easily from one ring to the next and without overshooting or jumping off the chain set. The "cage", the curved section of the derailleur that the chain passes through, should be approximately 2mm above the teeth of the chain ring. www.cobr.co.uk /cycle_workshop/channels/front_der.htm   (1043 words)

Front Derailleur Overview - 1-800-Bike-Pro / Buyer's Guide The front derailleur's job is to nudge the chain from one of the front chainrings to another, as smoothly as possible. It merely used the front derailleur cage to shove the chain laterally in a straight line to and from the chainrings. If the "capacity" of the front derailleur was 14 teeth, the difference between the largest and smallest chainring sizes must be 14 teeth or less. www.bikepro.com /products/front_derailleurs/fder_overview.html   (1079 words)

Replacing the Front Derailleur Replacing the front derailleur is one of those jobs that seems impossibly complicated. Set the limit screws so the inner wall of the derailleur cage is 2 mm (just less than 1/8 inch) away from the chain while in the small chainring and the biggest biggest cassette cog, and the outer wall is 2 mm from the chain while in big ring - smallest cog. The derailleur cage (the long thin "box" that moves with the chain) should be exactly parallel to the chainwheel. www.utahmountainbiking.com /fix/fderailr.htm   (503 words)

Gary Fisher > Glossary The two-armed mechanism that connects the pedals to the front chainring. The hook-shaped pieces of the frame which contact the hub of the front and rear wheels. The headset is the pair of bearings and bearing races (races are things that bearings sit in) at each end of the head tube that allow the fork to steer the bicycle smoothly. fisherbikes.com /utility/glossary.asp?...&term=derailleur,+front   (1922 words)

front derailleur modification   (Site not responding. Last check: 2007-10-22) The good thing is that almost all triple derailleurs have enough travel to handle four chainrings as long as the crankset is in the proper position. The basic problem is that derailleur cages are not designed to handle very large and very small chainrings at the same time. Raising the derailleur to clear a large outer chainring means the back of the cage is also raised and when you try to run a small triple or quad the chain may drag on the bottom of the cage. abundantadventures.com /mtfaq/frontderail/fr.derail.mods.html   (1205 words)

Front Derailleur My LBS said the OE Suntour derailleur would not be able to guide the chain through the jump. If you attempt to use a Shimano MTB front derailleur with the 46 36 26 combination, pay special attention to the Shimano specification for "minimum outer chainring / middle chainring capacity". If the derailleur hanger is a braze-on type you may have a problem getting the derailleur low enough. www.bikeforums.net /showthread.php?t=91387   (653 words)

Rivendell Catalog - Spirt Front Derailleur As different as this is, it's smarter, more intuitive, and way all front derailleurs should be. These are the last of the "top normal" front derailleurs. In any case, we include a section of housing with the derailleur but you have to order a cable stop based on the size of your downtube. www.rivendellbicycles.com /webalog/shifters_derailleurs/17107.html   (305 words)

Front derailleur question   (Site not responding. Last check: 2007-10-22) No matter how well I adjust the front derailleur (want the use of all 3 chainrings), I get a small amount of chain rub in the smallest 2 cogs when on the large chainring. AFAIK, the only effect #cogs has on front shifting is where the front cage sits on the index detents, and you originally posted that you're running in friction mode. I've set the low stop screw to a setting that limits the travel of the derailleur to where it is centered over the small chainring, and the high stop to where the inside cage arm will be centered over the large, if forced by hand. www.bikeforums.net /archive/index.php/t-45563   (1246 words)

[hpv] Gripshift with 105 front derailleur?   (Site not responding. Last check: 2007-10-22) I've used '98 RSX front derailleurs (identical to the 105 in geometry) with SRAM 7.0 shifters with no problems on a couple of bikes. MTB derailleurs (such as the LX) aren't designed for the 52t ring. RANS is doing the right thing by supplying a front derailleur that matches their chainring sizes. www.ihpva.org /pipermail/hpv/2001-August/018039.html   (261 words)

Bicycling Magazine - Tune Your Front Derailleur   (Site not responding. Last check: 2007-10-22) To adjust a derailleur already on your bike, unfasten the front derailleur cable and loosen the clamp. Looking from the side and using your fingers to pull the cage outward, position the bottom edge of the derailleur cage 1 to 3 millimeters (road is lower and mountain higher) above the tips of the chainring teeth. While hand-pedaling the cranks, turn the low-limit screw (usually the one farther from the frame, but the limit screw position varies on a lot of bikes--some have an H or an L next to the screws) clockwise until the chain won't drop into the small ring when you try to shift down. www.bicycling.com /article/0,3253,s1-1042,00.html?category_id=365   (518 words)

[hpv] Gripshift with 105 front derailleur?   (Site not responding. Last check: 2007-10-22) Shifting effort is very high and the total shifter travel to span the 3 chainrings is all between the indicated 1 and 2 marks. The 105 derailleur is designed to be used with 105 STI levers, hence the behavior you see. The R4403 isn't polished quite as nice as the 105 (it's in the Tiagra family), but it *works* much better in that application, and the finish is fine. www.ihpva.org /pipermail/hpv/2001-August/018043.html   (324 words)

Serotta Competition Bicycle Forums - Front derailleur clearance   (Site not responding. Last check: 2007-10-22) If the derailleur is hitting the rear only, it is possible that the seat tube is too slack. The clearance between the big chainring should be roughly the same (~1-2mm) front and rear. If your clearance problem is in the front only, I supose you could file the bottom and accomplish the same thing. www.serotta.com /forum/printthread.php?t=630   (442 words)

Shimano XTR Front Derailleur Reviews, Specs and Shopping   (Site not responding. Last check: 2007-10-22) This is for the newly re-designed 2003 XTR Front Deraileur. After continual frustration trying to get and keep previous derailleurs adjusted/shifting right, I rate this one 5 flamers for value (way worth the price), and 4 for overall cause of the rattle (cage could be another mm wider or something). On most front deraileurs, you have to often turn or push the shifter a little bit past the indexed point. www.mtbr.com /reviews/Derailleur/product_20867.shtml   (3211 words)

Dirt Rag Forums - Front Derailleur Turns out the derailleur didn't need an adjustment, the chain rings were covered in gook on the side next to the frame. Put the chain in the big ring in the front and see if the outer cage plate is aligned with the chainring. First, we need to know the age and at what stage of toastness the offending derailleur, cranks, chainrings, chain, and/or cassette occupy at the moment. www.dirtragmag.com /forums/showthread.php?t=1644   (702 words)

front derailleur mounting on p-38 - 'BentRider Online Forums There's a little rubber bushing surrounding the tube onto which the front derailleur clamps on the P-38. Assuming that LCD tubing is in one camp or the other you may be able to buy a derailleur or the clamping portion in the correct size. By rotating the spacer, the derailleur can be moved sideways by perhaps 1/2 inch. www.bentrideronline.com /messageboard/showthread.php?t=7837   (1030 words)

Front Derailleur When I'm in my 53 tooth front chain ring and 17 in the rear my chain starts to rub the front derailleur cage. The reason I don't like it is because you can't trim the front derailleur (on the cheaper groups, there are only two FD positions). I bet you do(but not if the front is a 7 or 8 speed tiple) if they are adjusted right and you know how to use it. www.cyclingforums.com /t-163870-15-1.html   (1000 words)

Hostel Shoppe - Front Derailleur Cable Installation On most 'bents with an adjustable boom, we remove the entire boom/crankset assembly which requires disconnecting the front derailleur cable. A common reassembly mistake is improper front derailleur cable attachment - we've even seen other bike shops do it - *gasp!* The correct way is shown below. Many people make the mistake of using the leverage tab as a cable pinch by running the cable UNDER the leverage tab - this changes the pulling leverage of the front shifter and makes it impossible to properly adjust the front derailleur. www.hostelshoppe.com /tech_frontderail.php   (130 words)

Shimano LX front Reviews, Specs and Shopping   (Site not responding. Last check: 2007-10-22) First off, I used a Deore front derailleur for 3 years on my hardtail with no problems (and that includes hard riding on AZ's rocky/technical terrain, including 24-hour and other racing), so props to Shimano for that. An LX front derailer doesn't have the chi-chi factor of expensive stuff, but no one looks at front derailers anyway. I even endoed and had the front derailer land on a rock, and while it was out of line, I fixed it and it works. www.mtbr.com /reviews/Derailleur/product_20848.shtml   (3640 words)
