How To Remove Chain Guard

Hi,

I am buying a new wheel, it has a Shimano FC-5703 triple ring crankset, 50X39X30T, bcd 130mm.

I am a coincidental rider, and really desire some type of chainguard on hither and so that I tin ride in jeans without need for a leg wrap to proceed my pants leg out of the chainrings.

I practice not know what the difference is betwixt a "bash guard" and a "chainring guard / "chain baby-sit".

Regardless, what is the all-time way to achieve some type of chainguard on hither?  What will I need?  I tin find concatenation guards sold on ebay made by Driveline, but is that the correct way to get?  If so, how do I install it and what volition I demand in the way of tools?

I would adopt to keep all 3 chainrings if possible, just if not, how hard is it to remove the largest chainring on this FC-5703 and install a chainguard/bashguard?  I really would like to avoid removing the whole creepo assembly or crank arm.

Thanks in accelerate,

wnload and look at this Shimano techdoc:  EV-FC-5703-3004B

which shows you how it goes together.  Y'all will need to remove the five detail 13 bolts.  For the outside you lot will need the tool that fits the head.  On about this is a 4mm hex key, but it appears that Shimano uses Torx on some.  For the back side I usually employ a very wide bladed screw driver - but I always remove the right crank arm to install the chain baby-sit.

The Driveline chain/bash guards are premium products, very well made, and nice looking.  Yous tin use a 50T 130mm BCD, or a 52T 130mm BCD for your application.  On our tandem, we have a 54T large ring, and used a Driveline 56T model.

The Driveline chain/fustigate guard comes with the required hardware to mount information technology to the outside of the big ring so that you exercise non give upward the triple.  You can also mount it in place of your big ring, using the hardware that is currently on your crankset.  The Driveline hardware is longer versions of item thirteen shown in the above document - the Driveline hardware uses a 4mm hex fundamental, plus v spacer to position the concatenation guard away from the big ring.

Hi Nigel,

Thanks for the splendid reply.

Let me ask your stance... I never use the large chainring because of the type of riding that I do (lower speeds, lots of hills).  Knowing that, do you think it is smarter to just replace the 50T chainring with a guard?  (The just reason I thought about keeping all 3 chainrings was fear that installation would exist more hard if I were to remove one of the rings, just it seems every bit though the 50T ring will exist basically asunder with this installation anyway?)

If yes that information technology makes sense to merely supercede the 50T with a baby-sit, I imagine that information technology would be smart to size the bashguard according to the middle chainring, in this case, a 39T? -- since that would be the biggest chainring that would be installed.

If I were to supplant the 50T chainring, is the Driveline baby-sit good enough quality, or should I go with something different.  I see FSA makes them, and I come across surplus Shimano Alfine FC-S501 39T chainring guard on ebay for $x shipped.  Not trying to salve coin simply just become something that volition mount easy and with good build quality.

I know that I would have to adjust the FD to prevent it from shifting into the large chainring, I believe my adjusting the H screw to limit travel.  I think my chain should be fine, as I cannot see why anything would have changed equally the gear that I always employ would all the same be what I always use.

FYI - I bought a Park Chainring nut wrench tool final dark, which should make removing those 5 screws a little easier.

You are going to remove both the middle and large ring during the installation of the chain guard.  It is the same amount of work to put things dorsum together if you keep or remove the big ring.  The only benefit I can run into from removing it is loosing a few grams - you could shave your head and get the same savings.....

The downside of removing the big ring is adjustment of the FD - I do not know if yous can screw the H limit spiral in far enough.

The Driveline ones are height quality.  There are no better.  Some of the other branded ones (FSA) appear to be made by the same company - the CNC machining is identical.

I would go on the triple, as information technology is less work (no FD aligning) and less risk (FD adjustment range might not be enough); and go with a 50T or 52T baby-sit.  Color choice may drive you to 50T or 52T.  Note that the 1 in my film is a 53T chain guard with a 52T ring backside information technology.

Solid communication, cheers very much!

I will go with your suggestion, proceed the 50T and use a driveline 50T guard (which is available in the color that matches my bike, blackness).

I recently ordered a driveline guard for my 48T concatenation ring.  Unfortunately, doesnt expect similar any of the mounting holes line upwardly... my fault for not verifying before ordering.

Does anyone know if there is a guard compatible with my ring shown in pics?  All the driveline stuff seems similar the BCD is too pocket-sized.  The mounting holes on mine are on the big outer band, around 7" BC, whereas drivelines are 104mm (iv")

Any aid greatly appreciated.

You practise not testify picture of the guard, but if its similar the one in photos above made to mount to the crank and you cannot get one that mounts to the rings you either need to drill new holes in the guard or become a new crank. Holes are cheaper.

Never Surrender!!!

Thank you, yes the guard is like to this one...

Volition demand the smaller hardware every bit well, as the ones that came with the guard are too big for the holes in my ring.

Sorry; I am not aware of any CG that volition fit your electric current rings, without and so drilling.

If you are up to it, I'd become with a 48T, BCD 110mm  unit similar this one:
http://www.ebay.com/itm/Driveline-Concatenation-Guard-48T-BCD-110mm-110g-Black-/140922746198?hash=item20cfa67556:chiliad:ocgAAMXQ~TtRLhPt
Drill and tap M6 holes in your present outer chainring, and apply spacers and M6 button head screws which will fit nicely in the counter bored holes of the Driveline CG.

Alternatively, just get a new crankset with CG like this i:
https://www.amazon.com/Shimano-M131-Crankset-170mm-48/dp/B003ZMDJW6/ref=sr_1_1?s=outdoor-recreation&ie=UTF8&qid=1485050870&sr=i-1&keywords=m131

It uses a 122mm (±2mm is okay) bottom subclass - measure out what you have.
