  No action on wheels in cold conditions
Posted by: harishankar - 12-08-2016, 04:23 PM - Forum: Wheels & Hubs - Replies (4)

I recently bought a second hand Giant Upland SE and to be frank, it is my first bike with multiple gears. The bike functioned normally for the first day or two. I could shift between all the gears. When the bike is stored indoors, the pedal and wheel work fine but once I take it out in the cold (anywhere from -10 to -30 degrees celsius), the pedals rotate freely and have no action on the wheel. Also I am not able use some gears on the rear wheel. Can anyone please help with an explanation and solution?


  What kind of valve is this (on a kids bike)?
Posted by: rhubear - 12-04-2016, 03:31 PM - Forum: Tires & Tubes - Replies (3)

Top of valve looks like Shrader but is smaller (5mm).

Core unscrews easily using nut shown.

Is this an alternate Presta version valve, so if I'm using a pump / compressor with car / Shrader attachment, would I just need a Presta to Shrader adaptor?   Tnx

  Chain dropping?
Posted by: neilbardsley - 11-07-2016, 11:50 AM - Forum: Chain, Chainrings & Sprockets - No Replies

I'm having an issue on my CX bike. Which is shimano with 38/48. On the last 2 rides when I'm in the lowest gear on the cassette my chain drops off the small chain ring. It doesn't happen on the 2nd from lowest gear on the cassette.

I decided that maybe my rear mech was limited enough so perhaps was pulling the chain off at an angle. Therefore I played with the Lo limiter screw and indexing adjustment to ensure that wasn't the case. On on my bike stand it was fine but once riding the bike again it dropped? Given that it has only just started happening could be be wear related? My chain is becoming loose? If that is the case then why doesn't it drop on on the 2nd lowest gear where the chain has more slake? Perhaps my chain ring has worn so it is easier for the chain to drop off? Maybe i need to adjust the angle of the rear derailleur to the cassette? Any help is appreciated.


  Looking to rebuild old project bike :) Not sure how to find compatible parts
Posted by: JoshTrevisiol - 10-28-2016, 08:05 AM - Forum: General Questions - Replies (5)

I made a post a long while back looking for info on replacing my derailleur and painkiller was wonderfully helpful in providing info about how serious the problem actually was with more than just the derailleur. Smile

Now I've finally arrived at a point where I've got the time and money to bring my old bike out of the garage and back to the road. I originally received the bike from my uncle in rough condition several years ago. It hasn't changed much since aside from brakes/rims/tires replacement, but I'm definitely certain about rebuilding it. 
I'm looking to learn how to identify compatible parts for the following: cranks, pedals, sprockets, chain, rear cogs, shifters, and front/rear derailleurs. I've replaced a lot of parts before, but never this much and I'm not sure where to begin looking for parts that work well together. Shopping on amazon is really intimidating not knowing what parts are compatible.

We have a super cool bike co-op here in my town so I've got a place to do the build with the correct tools. The aim is to make it into a reliable mid-distance bike so I can do my beach rides again.

It truly is a shame I've let the bike get to this level of wear; I'm hoping that learning more about the parts will help me understand how to keep it in good condition after the rebuild.

  Chain sticks when pack pedaling

I just finished a complete overhaul if the bike. Everything was cleaned, bearings washed and packed in fresh grease.

When I went to live the chain, I noticed that back pedalling causes the chain to stick:

  BMX Bottom Bracket Creaking and Clicking
Posted by: felpel102 - 10-15-2016, 11:04 AM - Forum: Bottom Brackets - Replies (2)

Hi, I received my brand new BMX last week, and already on the next day after I assembled everything I noticed an annoying creaking noise and felt some kind of clicking of the cranks under load, for example if I ride uphill. I disassembled the whole bottom bracket, cleaned everything (althout everything was clean and greased already) and regreased it. Nothing changed. What should I do? Is this normal for a new bike and will the clicking just disapper after some more rides? It's an american bb and a cheap old school BMX.


  Is it tires
Posted by: GeorgeET - 10-14-2016, 05:17 AM - Forum: Tires & Tubes - Replies (2)

Took a ride on my MB today on a trail. it was 88 degrees here in Texas. still. It was err... challenging. Got home and realized I lost something so I took my road bike down the same path since it was hard packed dirt. It was a breeze what a difference.

Now the MB is maybe 8lbs heavier and has dirt tires, is it mostly the tires or both extra weight and tires. I mean its only about 8lbs. Its 26X1.95 mb and 27X1.25 road tires.

Any old timers still out there to chime in. :-))


  Cannondale BadBoy Replacement Sealed Bearings
Posted by: ebgt - 10-11-2016, 02:15 PM - Forum: Headsets - Replies (1)

I'm refurbishing my Cannondale:

http://www.bikepedia.com/QuickBike/BikeSpecs.aspx?year=2002&brand=Cannondale&model=Bad+Boy

I'm trying to replace the bearings from the headset, but am finding it difficult to get the right size. They are 30mm (inside diameter) X 44mm (outside diameter).

Regarding the angle, I'm not sure as I don't have a clear way to measure.

I contacted Cannondale and they said:

"Looking at the link you supplied this appears to be a generic 1 1/8” external headset. Cannondale do not offer these but your local bike shop should be able to get one for you from a different brand".

I asked my local bike shop, who spent a lot of time measuring & eventually pointed me toward a pair of bearings I bought online. But when they got here they were to small on the outside diameter.

Any ideas appreciated.


  Putting drop bars on Cannondale Badboy (2002) hybrid
Posted by: ebgt - 09-30-2016, 06:53 PM - Forum: Brakes & Levers - Replies (5)

Hi

I want to put drop bars on this bike:

http://www.bikepedia.com/QuickBike/BikeSpecs.aspx?year=2002&brand=Cannondale&model=Bad+Boy

Need to change the brakes & want to put on combi brakes & shifters, but I'm a bit naive about how easily/well this can work.

Have been looking at a few possibilities for levers on Amazon - e.g.:

https://www.amazon.co.uk/SHIMANO-ST2300-BRAKE-SHIFTER-DOUBLE/dp/B017XO7EX6/ref=sr_1_13?ie=UTF8&qid=1475240787&sr=8-13&keywords=shimano+handlebar+brake+and+shifter

My hybrid has 3 cogs on the crank and 9 on the back bracket - i.e. - 27 gears. The shifters above say they're for 16 gears - so presumably not the ones for me?

Am I going to find any appropriate shifters for the way my bike as set up at the moment? Or do I need to change the gearing or abandon the plan altogether?

Thanks  


  Cannonade Badboy (2002) fork removal
Posted by: ebgt - 09-30-2016, 06:37 PM - Forum: Frame & Forks - Replies (18)

Hi

I'm trying to get the forks off a Cannondale 2002 Badboy frame - this is the model:

http://www.bikepedia.com/QuickBike/BikeSpecs.aspx?year=2002&brand=Cannondale&model=Bad+Boy

But I can't see how to go about it. I suspect that the black washers have corroded round the neck & that's what's keeping it attached (see pictures). Tried soaking the washers in WD40. Tried tapping it with a wooden mallet, but don't want to hit it too hard.

Anyone got any ideas? Help much appreciated...

  Re-spray alloy Cannonade (US made frame)
Posted by: ebgt - 09-29-2016, 05:53 PM - Forum: General Questions - Replies (3)

Hi

I have an old Cannonade Bad Boy. Frame was made in the US. The paint has bubbled all over the place and the alloy has oxidised underneath it. I want to strip it - check the frames integrity and then re-spray it if it's not compromised.

Before anyone starts - I'm aware how about intensive stripping frames by hand is. I've done this with a couple of steel bikes.

Questions are:
What's the best paint stripper for an alloy bike? Nitromors? Is there something better?

What's the best primer for alloy? Have read this is good:

https://www.amazon.co.uk/U-Pol-ACID-Acid-Etch-Primer/dp/B006HFM5YG/ref=sr_1_fkmr1_1?ie=UTF8&qid=1475159078&sr=8-1-fkmr1&keywords=Upol+etch+primer+bike

What's the best paint. By best, I mean - most resilient to sweat & water. Want to avoid the oxidation for as long as possible (Hammerite?) (nb - looking for a matt black finish).

Thanks


  How thoroughly to clean BB before re greasing/assembling.
Posted by: Spifff - 09-22-2016, 01:24 PM - Forum: Bottom Brackets - Replies (2)

I've read a bunch of tutorials (including the sticky here) and the only part i'm unsure of is how thoroughly one must clean out all the old grease before regreasing and reassembling.

I've wiped everything down and it is reasonably clean. Wondering if that bit of grease stuck in the bearing ring will contaminate and ruin the new grease or if a bit of mixing doesn't matter and the cleaning step is just mentioned out of completeness?

And a secondary question would be what product to use to clean them. i don't currently have access to any solvents so i'd be buying something and just want to not end up with something overly harsh/dangerous or custom/expensive.

Also doing the rear hub with coaster brake. This is a kids 14" bike. I assume the same question applies there.

Any thoughts appreciated


  Pedal Washers ?

  Handlebar end plugs?
Posted by: !TREK4ME! - 09-17-2016, 02:51 AM - Forum: Stem & Handlebars - Replies (2)

Hey Guys,
Looking for an affordable place to purchase some bar end plugs. Don't need anything fancy, just the typical plastic ones will be fine. Play a lot of Bike Polo and they get chewed up quickly... and need to be replaced often. We keep the bar ends plugged, so no one gets "core sampled" Lol
The common size is 19.5mm or 3/4" inside diameter. 22.5 bar size. 
Is there something at hardware stores that will work in the fastener section? 
Thanks


  Schwinn meridian rear drive axle
Posted by: Slipinn - 09-15-2016, 11:31 AM - Forum: Wheels & Hubs - Replies (3)

Recently bought a slightly used 26" meridian trike. While replacing wider tires on the rear, I noticed an issue with the rear drive side wheel hub. The wheel is held on with a nut and single washer. The hub is not held firmly in a location on the axle and is able to slide back and forth on the axle a good half inch even though the nut is tightened all the way down to its bottom threads on the axle. The non drive side hub and wheel has very little play on its axle , perhaps a 1/8 inch and seems to run fine.

While the drive side hub slides back and forth and seems to be creating undue wear on the hub which is a hollow "D" shaped hub.
My question is should the rear axle have an even amount of axle sticking out of the bearings on both sides and thus allowing me to remove some of the play out of the drive side or was the rear axle designed this way for some reason to allow the drive hub to slide back and forth on the axle? To me it seems like if the play was removed the hub would not wallow out from sliding back and forth.
It looks like the solid rear axle is held on by two large nuts on each side seating it to the bearings and frame. Any help is appreciated.

  Stay spacing for 6-speed freewheel
Posted by: sammich - 09-11-2016, 08:21 PM - Forum: Chain, Chainrings & Sprockets - Replies (3)

I have an older frame with an ultra-6 freewheel.  When the rear wheel is removed the stays measure 122.78 (hub is a 120 for the ultra-6).  I can cold bend it out to 126, I'm sure, but do I need to if I just put a regular 6-speed freewheel on?  I'm not sure how tight that would be as far as the chain scraping the frame.  has anybody tried it?  Has anybody bent a 120 out to 126 or 130 without problems?


  Chain wear indicators
Posted by: sammich - 09-10-2016, 08:48 PM - Forum: Chain, Chainrings & Sprockets - Replies (2)

I recently picked up a Park CC-3.2 to put in my portable bike tool-bag (12 inch ruler won't fit).  With it one of my chains that measures fine with the ruler, fails, even at the .75 side.  Reading on the subject states that the CC-3.2 doesn't take into account roller wear, which the Shimano TL-CN41 does. So, I took a popsicle stick (perfect thickness) and shaped it to press the roller nearest the drop-in end of the Park to give similar results to the Shimano and eliminate roller wear anomalies.  Sure enough, measurements come out differently, and what "failed" previously with the Park, now passes.  My question(s):  Is the Park CC-3.2 cut to compensate for roller wear to a point (meaning longer than it would be if the rollers were both pressed against their links in the same direction, as with the Shimano or my popsicle stick)?  If so, my invention would be inaccurate.  Has anyone measured with calipers (vernier) these two tools to see if they are the same distance at their measuring points?
Thanks for any insights or help.
