What amount of bicycle fasten wear ('stretch') is reasonable, beforehand prejudice to sprockets ensue?
Question:Have seen 1/16 inch within 12 inches (12 links) referred to as time to change (www.sheldonbrown.com/chains) and would approaching to gauge the reach of opinion on this number.
I am approaching this wear smooth now, though I own religiously (weekly) cleaned the chain next to a cleaning tool (BB brand) and 'gallons' of citrus-type solvent and water, and own lubed with a synthetic grease for wet conditions (Pedro's) everyday. Shoulders here are habitually sand-covered or muddy, and I often must commute in/after downpours.
To be precise, my Shimano HG rigid (with 9-spd cassete) is at 1/32 stretch after about 5 months and 2000 km (about 1,250 miles). This beg a secondary request for information: Is this a reasonable wear rate?
Thanks for your concept.
Answers:
Hi there. You provide a great deal of details and so do the other respondents.
However, if you're being that specific and precise, you're probably thinking course too hard roughly speaking this:
First riding conditions vary. Sounds close to you're riding in some relatively rough conditions so your chain wear will be greater.
Second, you seem to spend profoundly of time conditioning your drivetrain. While I certainly applaud you for doing so, do you really hold that much free time?
Bottom line is that strange chains are cheap (in the grand hatch up of things) -- you can't fill up most cars beside a tank of gas for the price of a clean chain. Factor contained by the time you spend caring for your tie up (along with aggravation of wondering how long you should use a chain) and you might as resourcefully replace your chain every 1000 miles (or even sooner if you'd like).
Don't draw from me wrong, taking care of your equipment is a really biddable idea and some citizens live to do nothing more than that. However, if you're so worried just about damaging your backside cogs, just replace the secure more frequently than you think you should...it's cheap insurance and indeed less time consuming than constantly wash your drivetrain.
P.S. If you're worried about the environmetal impact of replacinig your fasten, you can always recycle the manacle.
Man that is exceedingly precise. I know Park has a tool that can calculate stretch. The website also has formulas for fit and size. http://www.parktool.com/repair/readhowto...
If your not getting the life span out of your chain you might want to procure a stronger chain. Maybe titanium if within your budget.
Well, you've already got the details right and freshly don't want to buy a chain?
Okay, the Dura-Ace/XTR is much harder stuff and not as prone to stretch.
Yes, 1/16th is correct for being in safe limitations.
2000 miles of open road or 1000 miles of city is the correct numeral for Shimano and SRAM chains. Wipperman (Campy) can go twice that distance at roughly speaking twice that cost. Same $ per mile. Many mountain bike riders run the Wipperman chain next to Shimano gears. In my opinion, this isn't a righteous idea unless that's the with the sole purpose chain you can't snap.
Try this:
Before you put the tentative chain on the bike, clear up it (the chain) with Simple Green and dishwashing gooey to remove the cosmoline. The next daytime flood it with Singer Sewing Machine grease rubbing it in deeply well next to a washrag. This lubes the inside of the chain. Dry it very well. Now, apply EPIC (clear form of White-Lightening) to the chain to formulate it non-stick. EPIC is clear, and thus effective. Goopy cuff lubes don't do anything but fall sour. Continue using EPIC throughout the life of the tie up.
Properly broken in, a Dura Ace manacle could possibly last the proper 2000 or more miles that you should expect.
Feel free to apply EPIC plus washrag to the fasten to "help" it with the dirt. This in reality works well, even if you're contained by a hurry. It will knock off seriously of dirt and bring the friction down to within 10% of a freshly cleaned secure.
Oh, and did you measure pin center to pin center?
An exception: The 1/32 stretch is adequate for steel cassettes, but not for titanium cassette.
Yes, I agree with Sheldon Brown on adjectives but 1 topic, and that would be 26" tires and that the oval contact patch of the mountain "slick" is, in my judgment neither as safe, nor as nippy as the road bike tire with its pencil shaped contact, and, surrounded by my opinion various of the mildy treaded (road) 26" tires can, in certainty, match the performing of road bike tires while the mountain "slick" cannot. He says the in front of. Hands-on experience conflicts in this one travel case.
Other than this one item, I have not found any inaccuracy within any of his articles. They are enjoyable and slightly reliable.
So, if he says its time to buy a tie up. . .then its time to buy a manacle. ;)
My rule of thumb was 3 months or 12 miles. I believe the Shimano or Sedis rule be 2500km, so you are about here at 1200 miles. I belive this is a reasonable rate of wear.
The "feeble rule" I used to see a lot be 1/8 of an inch, at which point you would need to replace the entire drivetrain, so that be way too much.
Afterreading your story I'm worried in the order of you rear hub abd bottom bracket. If you are seeing that much mud and sand, and wash the chain next to citrus the bearing grease/cavity may be contaminated. It's a headache, but I like to overhaul my hubs at leas twice a year - Seattle. The Shimano grease is excellent.
Good luck.
in recent times change the cash when you notice ANY stretching.. you'll enjoy durable sprockets and chainrings
Well I am a bmx racer and I have never gone as far as to truly measure the manacle stretch. I can feel when the secure is starting to wear. I usually ride really hard on them and will adjust them around 1-2 months if they havent broke yet. Even if I havent rode super frozen on them before a national I will vary the chain to receive sure im on somthing fresh. But for just a regular rider 2-3 months is average depending on how unyielding you are riding. I say once you can quality that it is stretched change it regaudless of what the guage say.
How do you sprint which gear you use? i only want to own some thought of waht everybody use?
Answers:
All depends on the specifics. Road sprinting is complicated and takes experience to do powerfully, I can't sum it up for you in a pattern note.
But... most adjectives mistakes I see noobie racers making:
- way too high-ranking a gear, like 54x13. The push button is leg speed and acceleration; you want to be able to go underwater hard and verbs accelerating to the procession.
- going way to far from the row. it's only really possible to stir a MAX for 8-10 seconds; after that you're losing power. timing is everything.
Depends on the terrain and how strong you are - I am usually surrounded by 54x13.
I agree with Flun11, nearby.
I myself start (of course depending on situations) with 53x15 consequently go high to 13 or 12 (but remember, the way bike gears are setup, these change have to done, prior to the "real" sprint)- so you'd better be up to speed by later. Anyways, I'm not the strongest sprinter, so I know I need as big cadence as possible to build up speed. Then because of how my leg muscles are made of, I step to the 13/12 teeth in the reverse. So, think of going through your car's nouns. At certain RPM, a translation in gear is needed. But some stronger sprinters, they start and finish next to the highest possible! **jealous** haha
But it is more or less timing and when to react.
Leg power and speed surrounded by a major segment, but not the only member of winning sprints.
Good luck!

Couple of 50 year olds looking to buy a tandem bike for the occasional weekend ride. Any recommendation?
Question:Road bike vs sport vs cruiser?? Is a $400 bike a legitimate alternative?
Answers:
How heavy are you? How strong / in a hurry / serious?
I'd avoid the cheapo cruiser types, and a $400 tandem just scare me. Sorry, but when you have 2 adults, the physics cause a lot more stress on every segment of the bike... buy quality.
Major cities hold tandem clubs, look yours up and show up at a meeting. Also google a bit, near are tandem discussion groups and websites that sell used etc.
Avoid ebay... too unyielding to inspect before you buy.
50...i would run with a tandem wheelchair...j/k.
what fun11 sed. Tandems, uhm, riding a tandem can any cure or kill a relationship, they cart a special kind of communication and huge ammount of experience smooth on both riders.
It's great that you're riding but sounds like you are simply starting out and tandem might not be the way to turn.
Also "Cheap" tandems are dangerous. You hold the weight and power of two riders on basicly indistinguishable frame, wheels, power train and *brakes* as 1 single bike.
It must carry out flawlessly, your bike handleing skills must be flawless.
Suggest getting two single bikes and helmets if just starting out and rob it from there.
Wife and I are both over 50, we enjoy a tandem and used to ride all over the place. Now I can't win her to ride.
Wanna buy ours?
