  Change levers to thumb shifters
Posted by: azjd2009 - 04-09-2016, 03:10 AM - Forum: Derailleurs & Shifters - Replies (3)

I have an old 1984 Miyata Model 100
and I plan on replacing the drop handlebar with straight bar.

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.

  3 flats in a row/hole next to Presta valve
Posted by: fnezchad - 03-19-2016, 05:26 PM - Forum: Tires & Tubes - Replies (2)

I pulled my bike out from a winter hiatus and got a flat on my first ride.  The hole was right next to the valve.  I bought two more tubes, did a change, went on a ride and got a flat in the same spot within ten minutes.  I replaced it with the 2nd tube and the same thing happened within 10 minutes again, in the same spot.    See photo to see where the hole is appearing.  Also the 2nd photo shows how the rim strip appears to have shifted to the side.  Would that be shifting and rubbing the damaged area?  Are those things supposed to be glued down and not shifting?  I suspected that maybe I was tightening the nut too much and was careful on the last tube but it happened again.  Any advice?

  Tire & wheel sizes & matches
Posted by: budstutor - 03-16-2016, 07:56 PM - Forum: Tires & Tubes - Replies (2)

Will a 30, 32 or 40mm tire run OK on a 35mm rim?  Both 700c
That is 700c x 30 (32 or 40) tire on a 700c 35 rim. 
Is there a table to use for checking various tire/wheel compatibility?
I'm concerned about bulging one way and pinch flats if too small
Thanks

  Rear wheel keeps shifting
Posted by: NotRequired - 03-14-2016, 09:01 PM - Forum: Wheels & Hubs - Replies (1)

I just tuned my '76 Schwinn cruiser up for spring, and after riding as far as my daughter's bus stop my rear wheel has shifted over far enough that the tire is hard against the frame. So I readjust, tighten it back down, and in the same time my wheel has shifted again. It's gone as tight as it can. I'm wondering if the mounting brackets of the fender are causing the nut to slip. Perhaps moving them to the inside of the frame would help? Any suggestions?

Edit: It only seems to be the drive side that slips. The chain is loose and the tire presses against the non-drive side under the seat post at the bottom of the frame.


  HB M960 hub overhaul
Posted by: cyclegranny - 03-12-2016, 05:47 PM - Forum: Wheels & Hubs - Replies (3)

So I have this lovely ti tourer with shimano xtr hbm960 hubs, and I am hoping to service these hubs. I see a metal cap on both ends of the hubs both front and back and the metal cap has a space that looks like I can put a flat head screw driver into to pry it off, it has no flats like the other cones I've dealt with. Can't find how to on the internet. Has anyone dealt with these hubs?

  STI shifter problem
Posted by: dude - 02-29-2016, 12:48 PM - Forum: Derailleurs & Shifters - Replies (2)

I have one of these old STI shifters from the early 90's

https://drive.google.com/file/d/0By-S838OebDHUnRnSDd2b1dRajQ/view?usp=sharing

I can shift between the center and small chainwheels, but not from the center up to the big one.
The button goes all the way without resistance.

Any way to fix this or is is screwed for good?

Thanks in advance!

Has anyone heard about a recall on Focus bikes with the acros headset. I have seen something on their website relating to the Izalco. I have a Cayo that seems to share the same headset. Just trying to do some research before I contact my LBS. They haven't been overly helpful since I bought a very good but expensive bike from them. Cheers Stevo


  Cutting carbon seat post
Posted by: ajstevo - 02-24-2016, 08:10 AM - Forum: Saddles & Seatposts - Replies (2)

I am going to replace the dropper seat post on my wifes Specialized Rumour mountain bike. She wants me to fit a lighter carbon post as she does not use the dropper post. My question is I have a 400mm long post. I need to cut about 70mm off the bottom to allow it to fit into her small frame. Will this cause any issues? Seems like a good idea to me but I've broken plenty of things before.

Cheers Stevo

I have a 1987 Cannondale racing road bike that I have been using to ride on crushed stone and paved trails. The wheels have worn out and need replacing. I was wondering if I could get a slightly wider wheel that could support a wider tire. The crushed stone makes control a bit hard at times. I am looking for more stability from the bike.
I like the feel of the bike and am very comfortable with the road set up. I would rather not have to buy a new bike.

Hey guys, How is everyone? I haven't been here in a while but have been riding my butt off. Came by to show my newest toy off. This thing is Ridiculous! It makes me laugh the entire time I ride. It is a Bunch of fun! Got a good deal on it at the swap meet in Westminster Md. Lots of Good stuff there. Could not pass up this at $600 new with warranty and tuneups. I do most of my own tuneups now though, They are there if needed. Starting to contemplate some changes to the setup. It is currently a 1x9 with 33t chainring and 11-34 cassette. Thinking of going 1x10 with a 11-40 cassette. Looking at a few x9 groups to replace x4. The x4 works but the x9 works better! It is running a 4.9" tire and it will climb trees with the 11-40 or 42T setup. Hope all has been well for you folks.

  Bike tire replacement
Posted by: michaelcogburn.c - 02-14-2016, 10:11 AM - Forum: Tires & Tubes - Replies (1)

I've had my mountain bike for 5 years and I've never had to change the tires. Past 3 months or so I've been getting more and more frequent flats, and now there is a hole straight through the top of my rear tire.

Yesterday I notices the hole, so I wanted to replace it with a new tire. What type of tires at nowadays works good in term for mountain bikes.


  What tool is needed to remove this freewheel?
Posted by: dillmac - 02-10-2016, 04:08 PM - Forum: Wheels & Hubs - Replies (7)

Hello,

I was wondering if someone could recommend to me which removal tool is needed to remove this freewheel? I recently broke a couple spokes and the freewheel needs to be removed to access the hole to put a new spoke in. I put the ruler there to measure the diameter of the space, it's about 35mm-ish. I was looking at park tools freewheel recommendation site, but don't see one that would necessarily match. Would the FR-6 or FR-8 work? Thanks!

The bike in question is a Public Bikes V1. The Freewheel is Tri-Diamond and the hub is Shunfeng.

  BB stuck
Posted by: Lighttower - 02-06-2016, 11:08 AM - Forum: Bottom Brackets - Replies (2)

Hi again! Smile

I had some problems on my MTB suntour BB recently, first it made some noise, than it started wobbling, so I decided to replace it. It is a 68/122.5 sealed square tapered BB, so I bought the same thing just a Shimano.

I tried to remove the non drive side, no luck it is stuck, I tried to remove the drive side and it came off very easily, the sealed BB was open, the ballbearings rolled out and the plastic ring that holds the ballbearings in place was torn (so I guess it was a good decision to open it up).

I tried to remove the other side without any luck (for over an hour now), it is stuck. I don't have a pipe to extend my tool. The whole cartridge outside case is still inside, so applying any kind of fluids to soften up the BB is kinda difficult (and I don't even know what I should use). The cartridge case is thick and long, so I don't really see a way to cut it up.

I think the BB was a 73/122.5 and they tried to wrench it on really hard, so that it fits. I checked the measurements, contacted the manufacturer, read the users manual etc. it is definitely a 68.

My only idea was to ask my FLBS to help me remove it, but I hope you guys might be able to help me out with an idea.
