Posted by: aegis - 07-24-2016, 09:25 AM - Forum: Wheels & Hubs - Replies (5)

Hi

We have a hand me down bike which has been in the family for 30+ years. It's original ower is now in her fourties!!! I'm attached to this bike because the memories I have with my dad riding it.

It has rusted underneath the chrome coating it had so it now all pitted.

  Rear wheel noise - help please
Posted by: luckstar69 - 07-19-2016, 10:42 AM - Forum: Wheels & Hubs - Replies (4)

Hi everyone,

I have a very annoying creaky/rubby noise that I cant shift although I have narrowed it down to the rear wheel and not the bike.

I have a Giant Propel Advanced SL 0 Aero Race Road Bike 2016 3 months old and 1,000 miles with the SLR 0 Aero wheels 55mm.

The noise noise only happens (always takes 10 mins to warm up) when I'm seated and putting some power down uphill or on the flats. Now I know its not the BB as I have put my friends Mavic rear wheel on my bike and my SLR r/wheel on his Scott and he gets the same noise on his bike. He's 60kg and I'm 90kg and the noise was the same on his Scott Foil and on my Giant.

We swapped over the QR's and greased them and it made no difference.
I have tried 25mm contis and 23mm Giant factory tyres and it made no difference
I have lubed the spokes and no difference
Taken off the metal valve holder things and no difference
Check for brake rub - none

I'd be very grateful if anyone has an idea of what this noise cold be and how I could cure it?

Thank you


  Front derailleur can't shift from inner chainring to outer...sometimes
Posted by: Ptero - 07-17-2016, 07:09 AM - Forum: Derailleurs & Shifters - Replies (2)

So I'm having a very strange problem. I have an old 10 speed Chimo with friction shifters on the stem. A few months back I noticed that when I downshift to the inner chainring, my front derailleur can't shift it back up to the outer chainring. I put it off and only used 5 gears till I tried to fix it today. I flipped the bike upside down and played around with it and it shifted perfectly back and forth. I then righted the bike and had someone hold up the back tire. It also shifted just fine. But when I rode it, once again it refused to shift back up to the outer chainring. Any ideas what this could possibly be? Could my weight while riding be doing something that I'm not noticing? It's driving me bonkers!

Does anyone know if the rubber inserts in 'red cleats' can be purchased separately and if they can, where?  My cleats are like new, but the rubber has worn down to where the plastic cleat touches the pedal face and creaks.  Thanks.


  Bottom bracket... Strange style I haven't seen before?
Posted by: Quixoticish - 07-10-2016, 05:42 PM - Forum: Bottom Brackets - Replies (1)

Good afternoon internet hive mind. A friend has inherited a bike that has a wobbly bit somewhere inside the bottom bracket. I'm taking bits from old bikes to cannibalise into a new one to make it rideable and to be honest the whole thing is a great learning experience for me anyway, but I've hit a problem. In the past I've removed the bottom bracket with the correct tools, then to remove the bit that contains the ball bearings I just use an adjustable wrench to unscrew it. On this bike it isn't nice and hexagonal shaped to allow a wrench to grip properly, it keeps sliding off. It looks like some kind of unique tool is needed, can anyone assist me in removing this so I can replace the bottom bracket? I've attached a picture of the offending bit.

  Crankset repair.
Posted by: qAnAthemA - 07-07-2016, 03:29 PM - Forum: Cranks & Pedals - No Replies

Hi guys!

My bike has been damaged. The crankset is curved now. Sad [Image: cCYvrJ.jpg] [Image: JwJHhe.jpg] [Image: xCPb4B.jpg]
From the information I have found it is Suntour XCC 48/38/28 (http://www.gtbicycles.com/usa_en/2013/bikes/urban/sport/transeo-4-0). The problem is that I don't know the bottom bracket size and anything else. So do you have any ideas what crankset can replace my old one and please tell me what instruments do I need to replace it (right now I have moved and I don't have any instruments).

Thank you.


  Replacing crankset - chainline and bottom bracket question
Posted by: dax42 - 07-06-2016, 10:59 PM - Forum: Cranks & Pedals - No Replies

Hi all,

I have a bike that I'm doing up as a project and I need to replace the bottom bracket (square taper). Since the front chainring (single, 46 teeth) is pretty badly worn I was going to take the opportunity and replace that as well. But what to get as replacement?

At the back I've got a 6-speed freewheel with a chain line of 38 mm. The bike is nothing special, it's more for fun and the learning experience (my first project..), so I'd like to keep the costs down. I was looking at some budget cranksets on ebay but most of them don't specify what kind of bottom bracket length to use. How do I find a crankset/bottom bracket combination that will work and also give me a narrow enough chain line? Is it just a matter of trial and error (that could get quite expensive if I'm unlucky I guess..) or is there something I should look out for?

I found a cheap one that for a change specified BB and chain line: 131 mm BB and 50 mm chain line.
https://www.rosebikes.com/article/m-wave-single-crankset/aid:485066
Can I just use a shorter BB to get a narrower chain line or will that not fit? Do you know of a combination that could work?

Thanks a lot!

  Wheel size change
Posted by: onesaxplayer - 06-27-2016, 04:51 PM - Forum: Wheels & Hubs - Replies (1)

Hi all,

Someone just gave me a 32" cruiser bike. Yes, it's a boxstore bike, but they were kind enough to give it to me and I appreciate their generosity. The back tire has a gash in it, and I'm having a hard time finding a replacement. I'm contemplating downsizing the wheel set to a more common size. Seems like it will work as the bike is very simple: single speed, coaster brake. Spatial reasoning isn't my forte so sometimes I look at things like this thinking they will work, only to find out I'm mistaken. What do I need to think through on such a swap? Thanks in advance!!!

I have a 1997 Giant Ferrago.  Great bike, bulletproof.  I was changing the rear tube, and doing a bit of lube to both wheels.  When all was said and done, I had a left over spring that I think came off the bike.  But where?

Any ideas?

  My cool Schwinn
Posted by: thatcham84 - 06-16-2016, 02:26 PM - Forum: Show off your bike! - No Replies

This bike started out life a very heavy Schwinn Trailway
It was over 40 lbs. Now it is very near 21lbs. and Rocks!
It is now 21 pounds 6 ounces. I can trim about another 3oz. by moving to a XT rear derailleur and replacing the seat bolts with Ti bolts and rear derailleur bolts. But not today. This bike will probably never be lighter than 21 lbs. the frame is just to heavy.
Even now every part including bolts has been replaced with something lighter and only the frame is original.
All of the parts used to make this build where based on 2 criteria, long life and light in weight.
No added fluff,strictly business built.

I've owned this bike (1977 Schwinn Le Tour III) for about a month. For all I know, this has been there the entire time and I didn't notice it. It looks like someone took a tiny saw or something and cut into the lug. It looks to perfect to be a crack. I'm a novice when it comes to bike repair and I'm looking to learn what this might be. Is it a repair to a crack? Should I be looking for a new frame?

  Front derailleur drags on middle chainring?
Posted by: fionn88 - 06-09-2016, 01:21 PM - Forum: Derailleurs & Shifters - Replies (1)

Hi guys -- I'm new to the forum. Thanks for reading.

I'm fixing up a bike I've had for ~15 years that, sadly, I wasn't able to maintain. The bike is an 18-speed Royce Union mountain bike. Aside from new tubes/tires and a new chain, everything else is original (thumb shifters, both derailleurs are Shimano).

The original chain was just too rusted, so I replaced it, and it runs nicely now. Almost. It's fine on the granny chainring, and it's fine on the big ring, but when it's on the middle ring (the one that I tend to use the most), the chain drags across the inside of the derailleur cage. Previously (when I had been maintaining this bike regularly before knee issues made riding a nightmare), I had had to adjust the low limit on the derailleur to keep it from dragging when it was on the granny ring, and it had been fine until I had to stop riding.

I'm planning on using this as a commuter bike for the next year or so, not for trails or long treks (not yet, anyway).

Any thoughts on what I can do to fix the chain drag on the middle chainring? Any suggestions/advice would be much appreciated!

We have met this figure just after start of the trip. It was part of the wooden sculpture group near the entrance to the forest road.

As for me it looks like a pre-christian idol or just a depressive mushroom.

The places to visit:

Besides cute spring nature and surprisingly good and empty roads – there are two places to visit in this area: Moryntsi village, where is  Taras Shevchenko was born. His poetry was inspired by this place, its quite energy and he  have lost his virginity somewhere around in his 13, which is indirectly mentioned in one of his poems.

Open air museum in Moryntsi village.

The fact is that this type of building are super eco-friendly and they were naturally integrated in to landscape.  A kind of local Feng Shui.

Due to short trip time – all my bike bags and backpack were half-empty. The custom frame bag was constructed by me and I considered it like 80% successful. There are few improvements needed, such as one one more additional mounting point and smartphone pocket depth Smile.

Also we have successfully tested dehydrated hiking food manufactured in Ukraine. It keeps national cuisine taste.

Conclusion:

Central Ukraine remains a kind of “terra incognita” for hiking/cycling tourist. I’m not sure if there is some sense to come here just with tourist reason, but is you are already in Ukraine and have some time – there is sense for bike touring.

Note:

  • Use your MTB/hardtail bike instead of road bike. Roads surface can be on horrible level and looks like a moon surface. At the same time – almost all the roads during this trip was normal and has almost no traffic.
  • There is no much English-speaking people in villages,  but you can try to talk nerdy young people in cities. Ukraine is country of IT outsource, just lookup for coders around you.
  • You can take your bike to local trains, but there is no place for bike in a buses.
  • It’s quite safety in a village area, during years of hiking/cycling I had no one incident. At the same time – avoid placing your tent inside of city parks.


  setting up disc brakes on a frame not made for disc breaks
Posted by: Deadguy - 06-01-2016, 08:53 AM - Forum: Brakes & Levers - No Replies

My bike was stolen and i recently got it back... but some of the parts where switched out. They replaced my 27.5 inch forks with 26 inch shocks(pretty nice ones though) and my 27.5 single gear wheel with a 26 inch mtb wheel with a disc break disc on it. Finding a 27.5 has not been easy. And my breaks wont reach the 26 inch rim. I was thinking about ringing up some kind of extension to mount the break pads on.. then a friend said he had a disc break set up. But i dont have the mount holes on my fram for it.
Is there some kind of adapter i can mount on my frame to make it work with the disc breaks?

Any other ideas on how to rig breaks on it are appreciated! Thanks in advance!


  Hello Again! 80 Peugeot, 79 Gitane Mixte
Posted by: JanJ - 05-28-2016, 06:53 PM - Forum: General Questions - Replies (1)

Hello from NC!   Have been away a while....
Update of the 2 bikes I overhauled 1.5 years ago...

Peugeot got damaged during move, and Mayflower didn't cover it, even with my appeal...  So I dis-assembled derailleur, bent it back, and re-assembled it.. Rode it a few times..... Appears to be normal.... (I've had No issue with the ceramic bearings in Peugeot)

Gitane did not get damaged during move, but still throws chain on reverse pedaling (something that caused my mom to stop riding in 1980's).   My overhaul, steel bearings made chain issues better, but not perfect.

Daughter going to visit us, and wants to ride bikes...

So today I built the 3 bike receiver hitch carrier that's been sitting un-opened for 2+ years, and

both bikes now a Local Bike Shop for a look-see...
(Guy owns a 1982 Peugeot, and is familiar with Peugeot & Gitane's) 
I told him  I did  tear down and rebuild with new bearings, cables, brake pads.

He Did quick examine both and said they were both in very good shape...


  Rear Derailleurs
Posted by: Simon1001 - 05-28-2016, 05:02 PM - Forum: Derailleurs & Shifters - Replies (1)

Hi

My rear derailleur is horizontal to the bike frame as opposed to vertical.

I can see no obvious reason for this and am unsure of how to fix it.

The bike was shifting just fine until I literally put it down, picked it back up and went to take off and the rear derailleur had the before mentioned issue.

Any help would be much appreciated.


  7 speed bike / 5 speed shifter handle
Posted by: 6716 - 05-22-2016, 02:14 AM - Forum: Derailleurs & Shifters - Replies (1)

So I picked up a newer Schwinn Jaguar off of craigslist for my son.

This is the first bike I've had around in probably 30 years.

The guy I bought it from pointed out that he had replaced the broken stock 7-speed shifter handle with a 5-speed shifter handle. It rides fine and everything else seems to work. The kid wanted it so we brought it home.

I notice that first gear on the shifter is on the third largest sprocket.

Effectively the bike is set up for gears 3-7 at the moment. If I wanted to gear it down is there a way to set it to go from 2-6 or 1-5? Or is that the natural order of things that you work up from the smallest sprocket on the cassette and work your way up?

The kid is happy enough with it at the moment so it isn't an urgent thing.

I also see that I can buy a 7-speed shifter on line. Is there any magic to selecting the right one of those if I were to look at replacing the shifter?

Thanks
