  Single Speed Freewheel Removal Tool?
Posted by: !TREK4ME! - 05-21-2016, 01:34 AM - Forum: Chain, Chainrings & Sprockets - Replies (2)

Hey Guys,

Have a BMX bike that the single speed freewheel is worn out on. The problem is that the freewheel was installed backwards. So, the notches that the freewheel tool would grab on to the freewheel to remove, are on the inside of the wheel next to the spokes. 

There are two small holes that are 180 degrees apart from each other on the outside of the freewheel. 

Is there a tool to use these holes to get the freewheel off?... 

or is there another way to remove the freewheel? 

Thanks


  Repairing rusted chainstays on old Dawes
Posted by: stillstanden - 05-18-2016, 09:21 PM - Forum: Frame & Forks - Replies (2)

Hi.
This is my grandmother's beautiful old Dawes racer from the 60s/70s.
I intended to rebuild it to use as a commuter bike at uni. However I quickly discovered some really bad rust on the chainstays and a sizeable hole to boot. What I'm wandering is this - is it possible to fix this and who could I get to do it? Bear in mind that the clearance around the wheel (using 28mm tyres) is really minimal so any repair would have to be very precise and delicate so that the tyre wouldn't rub.
See photos below.

Thank you.

  Pairing dropbars levers with a flat-bar bike
Posted by: wtherapy - 05-17-2016, 04:21 AM - Forum: Brakes & Levers - Replies (2)

Hello,

I am interested in buying a fitness Canyon bike that can be seen at:

https://www.canyon.com/en-ro/fitness/roadlite/2016/roadlite-al-7-0.html

My primary goal with it is to use it with drop handlebars and I'm not interested in a regular road bike since this one supports wider tires (I'm about 95 kg weight), hydraulic disc brakes and I also want a big top tube to get a big seat post angle (with a Profile Design Fast-Forward seat post, the seat post angle can be increased by about 5 deg). My question is - can I use one of them:

https://www.bike24.com/p2141894.html
https://www.bike24.com/p2152044.html

with my own drop-handlebar and have it work without problems with the bike? If yes, can I use them with the brakes provided with the bike at canyon or do I need new brakes?

Thank you.


  Derailleur Spring - how to put it back on?
Posted by: thuzmund - 05-14-2016, 02:03 AM - Forum: Derailleurs & Shifters - Replies (2)

Hi everyone,

I am very new to bicycle mechanics, trying to get an old mountain bike running better. As I was scrubbing off years of gunk from the chain and derailleur, a piece popped off. I have included pics.

https://onedrive.live.com/redir?resid=9E519F39D9FB9823!1924&authkey=!ACOzLRPoJQNHcCY&v=3&ithint=photo%2cjpg

https://onedrive.live.com/redir?resid=9E519F39D9FB9823!1925&authkey=!AG-eux3wziP2kcs&v=3&ithint=photo%2cjpg

https://onedrive.live.com/redir?resid=9E519F39D9FB9823!1926&authkey=!AKwpuGRA42PvKe0&v=3&ithint=photo%2cjpg

There is a spring, and a hole apparently for the spring on one side. On the other side, I don't know how to assemble things back properly. I didn't think to take a picture of the assembly before that part removed itself!

I have tried to find a parts diagram but my bicycle is rather old. The spring looks like the one here, but mine doesn't have a threaded male post. http://bernd.sluka.de/Fahrrad/Shiman...05-GS_1997.gif

I can see that my derailleur reads "Shimano SIS," no additional numbers or anything.

I have a feeling that a retaining clip may have popped off, based on a groove I see in the male post. But also, the spring looks like it extends so as to lock itself into place somewhere with the female bracket. Try as I might, I cannot seem to exert the force to twist the spring 180 degrees to get it housed.

Any ideas would be great, because this has really challenged me! I wonder if I am approaching it wrong.

Thank you, I hope your experience can help me!


  Fixing up Dawes Discovery 201eq gents 2011
Posted by: dahe5575 - 05-10-2016, 11:45 AM - Forum: General Questions - Replies (3)

Hi all,
I have a Dawes Discovery 201eq gents from 2011 that I want to fix up after a couple of years without use. The goal is to get it into good enough shape that I can use it for commuting and some training. I know it's not ideal for training, but I can't afford a road bike at the moment. Also I need the Dawes bike for occasional family trips (with kid on the back) so that's why I want to fix it up rather than save up and buy a road bike right away.

Here are the original specs for the bike along with some status of them:

Frame type:             7005 aluminum (22 inch)
Fork type:                Hi-tensile steel
Rims type:        Alloy with CNC sidewall - ZC1000 rims by Alex(back wheel misshaped)
Hub front:        Alloy 36H
Hub rear:          Alloy 36H
Spokes:            14G steel
Tyres:              Kenda K-948 700 x 35c (broken)
Skewers:                QR
Shifters:            Shimano EF-50 21 speed (rusty wires)
Front derailleur: Shimano FD-C051
Rear derailleur: Shimano RD-TX51
Crankset:         48/38/28T with 170mm alloy crank (completely broken)
Cassette:           Shimano 14-34T (rusty)
Pedals:             Black resin with grey grip (completely broken)
Bottom bracket:   Semi-cartridge
Seat post:         Alloy 27.2mmx350mm
Saddle:             Dawes sports
Handlebars:       Steel riser
Stem:               Alloy quill
Headset:             Threaded 1.1/8”
Brakes:             Alloy V-brake (rusty wires, needs new pads at least)
Chain:               KMC Z51 (rusty)
Brake levers:       Shimano

So basically at bare minimum, I need to replace the crankset, pedals, tyres and do something about the slightly misshaped back wheel.

Any suggestions on what I should buy keeping in mind that I do want to use the bike for training as well as commuting? I would like to keep the total cost under 350-400$ and with that at least make it an upgrade over the original specs (since otherwise I might as well buy a cheap new commuter bike).
I'm open to all suggestions and if there's a good bike I could buy new that would be superior for my purposes and in my price range I'd be open for that too.

Thanks for the help. Let me know if there is any other info I can provide.


  Remove chain from front derailleur

I got a Shimano tourney front derailleur on my bike. Need to replace it. How to get the chain out?. I hope, I do not have to break a link on the chain. I see a rivet in one end of the metal. I do not see screw or  bolt tightening the two ends.


  Working on a Genesis V2100
Posted by: T-Box - 04-30-2016, 10:40 PM - Forum: General Questions - No Replies

I like the current frame of the V2100, its why I purchased it last June. Also, I am by no means a "serious" mtb'r and former dirt/vert rider, but being older now I generally ride in the city but dont care much for road bikes as sometimes I like to trail ride, so, that being said I do plan on upgrading everything on this frame, but not with any expensive components ofc.

My main question - Are there any decent BB/cranksets that will fit this frame...SRAM...anything other than the stock garbage, and yes I noticed that all hardware and components are junk.
I have seen other V2100 with upgraded shocks, front and rear so know thats not an issue, and ofc wheel set is basically a no brainer unless your a serious enthusiast.

Im assuming this would get me started, Shimano UN55 68 113 BB Square Taper Bottom Bracket?

Any and all information is gladly appreciated, Thank you.


  Need to press twice to get to lower clog
Posted by: dude - 04-30-2016, 01:10 PM - Forum: Derailleurs & Shifters - Replies (2)

I followed the instructions in this video
https://www.youtube.com/watch?v=tfBiXgf8JxI
but I still have the same problem on a Shimano Sora race bike.

With the front derailleur, when I want to switch down from a larger clog to a smaller one, I always have to press the shifter twice: the first time moves the derailleur just a little bit and the second time does the job.

Any hint?

  1977 Huffy Sun Country

My wife won a 1977 Huffy Sun Country on a local auction. This bike is equipped with a 3 speed hub. I am assuming that the bike was probably never properly maintained. I sprayed Gum-out into the hub to wash out the old oil/grease. My question is what type of oil and how much is needed. I have been thinking of using a light oil such as 3-in-1.

I have an older(vintage) bicycle, it,s a 7 speed using suntour radius parts. I want to change out my chain ring. Some say compatible with 9 or 10 speed, does it really matter? If I buy the same rings as 52/42 with the right BCD.


  Chain skips
Posted by: jacke - 04-19-2016, 04:14 AM - Forum: Chain, Chainrings & Sprockets - Replies (1)

I have a Bianchi with SRAM Red components.  The cassette is a 11-28 10 speed.  The crank is 53-39.  I recently put on a new SRAM 10 speed chain and the chain skipped while riding when I was applying heavy pressure to the pedals.  I then put the old chain back on and the problem went away.  It feels as if the skipping is coming from the cassette rather than the crank.  I tried it again with yet another new chain and had the same problem.  Is it possible that the cassette has worn with the chain and it won't work with a new chain?  I thought I might ask before spending the money on a new cassette.

Thank you,

Jack


  What was the first bicycling computer?
Posted by: DaverDee - 04-18-2016, 10:18 PM - Forum: Accessories & Clothing - Replies (1)

Hello.

Not looking to age myself but I have been enjoying cycling for decades.  And I recall the original bicycle computer coming out in the 1975-1979 time period.  However, I can recall the brand?

Does anyone remember?

What I think I remember is it was:
. Grey or silver color
. Square shaped with rounded edges
. Only a one line LCD display

Thank you.

  Repairing brazed steel frame

Hello,
My brazed steel frame has a crack at the connection between main frame and head tube (its a recumbent).  I am looking into repairing this myself, have some experience welding and brazing. Would I need an acetylene torch?  Is silver rods the kind I want to use?  Thank you for any advice.


  Is the upgrade worth it?
Posted by: kyle.temple - 04-15-2016, 06:44 PM - Forum: Bikes & Components - No Replies

So, I just bought myself a used Specialized shiv tri bike. Took it to the shop, and noticed that the previous owner had installed SRAM 11spd shifters, but kept the original 10spd drivetrain.. Needless to say, it shifts, but not very happily. Is it worth it to upgrade my entire drivetrain to SRAM 11spd? Or should I just bite the bullet and get either Di2 or eTap while i'm at it? Or should I not bother messing with it instead, and just let it be?


  Change levers to thumb shifters

I'd also like to replace the old lever shifters with thumb shifters on the handlebar. I'm sure this has been done a thousand times but I couldn't find any instructions in this forum.

Any help is appreciated.

  Can't find a fork replacement
Posted by: brandomos - 04-08-2016, 01:02 PM - Forum: Frame & Forks - Replies (2)

Hello fellow bikers!

The issue I currently have is I bought a Nashbar 2000 ETS from Craigslist.  It looked to be in amazing shape however once I rode it more I realized the forks are bent.  So for weeks now I've been on a hunt scouring the interwebs for a new fork.  I really didn't think it would be this difficult but here I am.

Here are photos of what I'm working with.  I've been converting my measurements from inch to mm.  As you can see the distance from center of axle to bottom of crown is 14" (355mm), axle to center of brake mount hole is about 14 3/8" (365mm) and axle to crown race is 15 1/2" (393mm).  Wheel size is 27 1/4 and tire size is 32-630.  The tires are dry rotted and need to be replaced so I can certainly use a smaller diameter if need be or if suggested.

It seems most new forks I find online the measurements are significantly different than my current fork.

Can any of you help shed some light on this for me?

  Frozen front suspension
Posted by: evannnc - 04-07-2016, 02:29 AM - Forum: Frame & Forks - Replies (1)

I purchased a used specialized hardrock with the original RST gila suspention fork, but it is frozen and won't move under normal use.  I've removed the lower screws and attempted to hit it with a rubber mallet like the guy in this video does to the exact same shock, but it won't move.  I've also gotten a car jack in between the break arm of the shock and the top of the fork, and i've cranked it up. the shock lowers move about an inch but then the jack pops out and they rebound back to where they were instantly and i have to lower the jack again to get it in.  what could be holding the shocks in place like this? they don't seem to be rusted closed since they move a little.

  Trek 7200 convert suspension fork to chromoly
Posted by: SteadyEddie - 03-26-2016, 05:52 PM - Forum: Frame & Forks - Replies (2)

Can anyone recommend a source for the appropriate chromoly fork to replace the more expensive RST suspension fork. I recently replaced my 7300 with a suspension SunTour but $170 at the bike shop was too much. Looking at migrating three Trek 72/7300 to chromoly rigids. All are size 17.5 to fit riders at 5'8".

I have seen craiglist list a salvage [ frozen bb ] 7300 but it was a 19 inch Trek. Would that fork fit the next size down, my 17 1/2's ??

Any pointers appreciated. I do most of my own repair work. Fairly technical knowledge wise etc.

THX.
