  Chain loosing grip with the chainrings
Posted by: Guest - 07-19-2008, 08:51 AM - Forum: Chain, Chainrings & Sprockets - Replies (5)

When I ride in a gear past 4 my chain starts to make a popping noise. It does it more and more the faster I go. It's like when you shift to 1st gear then stop on a hill then try to go again in first gear it loose grips with the chainrings. It looses grip with the rear chain rings for about a second then regains grip. This only happens when I go to any gear past 4. Also when I stand up to pedal faster the chain just makes this weird pop sound and I loose all my speed because it looses grip with the rear chain rings. So do you know what is wrong?

  Shimano XT hub skipping
Posted by: Guest - 07-19-2008, 08:44 AM - Forum: Wheels & Hubs - Replies (1)

Why does my Shimano XT hub skip one time (or click) when pedaling either hard or easy without the slipping of the chain to the cog? Could it be that I need a new freehub body or new rear hub?
Thank you,
Dan

  Gear changing manual?
Posted by: Guest - 07-19-2008, 08:04 AM - Forum: Riding Techniques - Replies (2)

Is there a manual that shows the correct way to change gears on my sc1800 mtb? Bike manufactures assume that everybody who rides knows how to change gears-which is bull-and don't include instructions when a person buys a bike.


  How much for a decent road bike?
Posted by: Guest - 07-19-2008, 08:00 AM - Forum: Bikes & Components - Replies (1)

Alex,

Your site has been very useful in helping me tune up an old junker bike a friend gave me. I've been using it to commute to my college campus (only 4 miles each way), but the bike won't last much longer and I need to replace it.

What should I expect to pay for a quality road bike that I will be using to commute to class and work, at least ten miles (total) per day?

Thanks!

  How do I find frame specifications?
Posted by: Guest - 07-19-2008, 07:18 AM - Forum: Frame & Forks - Replies (4)

I'd like to know how to measure the maximum tire thickness clearance on a particular bike frame. I can't find the specifications on the frame website, that's why I need some help here.

  What kind of suspension post do you have?
Posted by: Guest - 07-19-2008, 07:09 AM - Forum: Saddles & Seatposts - Replies (1)

I have noticed on one of your bikes what looks like a frame / casting / or moulding.
The item I refer to is the section between the seat post and the seat. I presume this is so that the seat can be moved further forward, or rearward, than is normally possible.
One of the family needs to have the seat further back than can be adjusted and something like this would be a boon. Do you know of a supplier that would supply this item and ship to the UK?
Thanks for any help

  My new cassette cluster is noisy
Posted by: Guest - 07-19-2008, 07:02 AM - Forum: Chain, Chainrings & Sprockets - Replies (4)

I replaced my cassette cluster with an exact replica per your demonstration, all went well. However, I took if for a ride and it didn't sound as smooth as my old broke in cassette cluster, do I need to give it some more break in time? My chain length seemed okay last time checked about 500 miles ago, but do I need to replace it, it looks fine, derailleur looks fine. Your take?
Thanks,
Greg

  Should I replace my wheel?
Posted by: Guest - 07-19-2008, 06:51 AM - Forum: Wheels & Hubs - Replies (5)

Hey I have a mountain bike, whose bearings seem to be damaged because the back wheels moves left to the right, what I don't know what to do is whether to get a replacement wheel with the bearings already installed, or buy new bearings to install on the wheel. What actually makes the wheel move, is it the bearing balls are out of placed. Correct me if I'm wrong...
Your suggestion would be truly appreciated.

  Request for a general tune-up tutorial
Posted by: Guest - 07-19-2008, 06:46 AM - Forum: General Questions - Replies (1)

I find your site and tutorials quite informative and appreciate you taking the time and effort to create them. However, I was wondering if you were ever thinking about doing a video on how a common cyclist would do a monthly/seasonal tuneup?

For instance, what things should be checked, cleaned, replaced, adjusted etc.?


  Flat tire tutorial?

Can you include more info on how to repair a flat tire. I still see quite a few people not working the bead of the tire to the bottom of the rim. Not doing this causes many of them to start using other tools than there hands.


  How do I tension and true my wheel?
Posted by: Guest - 07-19-2008, 06:39 AM - Forum: Wheels & Hubs - Replies (1)

Hi Alex, thank you for putting together this great website. I bent my rear rim on a pot hole. I bought a new rim and taped it to the old one and moved all the spokes over. I tightened all the spokes but too tight because it looked like a potato chip. I loosened them and got it fairly true but am have a hard time getting it radially true. I think I'm going to start over but how tight should all the spokes be before you start tightening and loosening to make the wheel laterally true? And, how should I true the wheel radially?

  Wheel Centering Question
Posted by: Guest - 07-19-2008, 06:35 AM - Forum: Wheels & Hubs - Replies (1)

I pulled a rear wheel from a specialized p2 and placed on specialized stumpjumper M4. This wheel has 9 cog cassette. The wheel was not centered -- it sits closer to non drive side. So to better center the wheel I swapped the nuts that secure position of inner nuts (those which hold bearings in place). The ones I swapped are the nuts that rest against inside of dropout (they have the etched lines in them). I did this because one was clearly larger than the other.
This improves the center of the wheel but it is still not centered. I guess I could shop for an even thinner nut (to go on drive side) but it can't be too thin as the cassette can't come into contact with the frame.
Is this a common problem? Anything else I should try to better center this wheel?
Thanks -joel


  Can I mount old brakes on a newer bike?
Posted by: Guest - 07-19-2008, 06:31 AM - Forum: Brakes & Levers - Replies (1)

The part on my frame where the V-brakes fit on to has broken off. Can I fit another type of brake? The frame has a bar above the brake with a hole in it like the old type of brakes.

  Gearing Question
Posted by: Guest - 07-19-2008, 06:26 AM - Forum: Chain, Chainrings & Sprockets - Replies (3)

Hi Alex, cool stuff. quick question:
I have a road bike with Shimano 105 double chainring cranks 53/39 and Sram 9speed 12-13-14-15-17-19-21-23-26. I'm thinking of doing a hilly century and some suggested I change the small chainring 39 to a smaller 30t (available for triple cranks) and then replace the 12t, 14t & 26t cogs of the rear cassette with 25t, 27t & 30t... is that really practical? or do-able at all?
Thanks!
Jason


  Chain slips a tooth
Posted by: Guest - 07-18-2008, 11:00 AM - Forum: Chain, Chainrings & Sprockets - Replies (1)

Hi Alex,
After a year of not using my ATB, I decided to clean the dust off it and go for a ride. After an afternoon of cleaning, adjusting the shifters & breaks I took it out for a spin, but every time I wanted to put some extra pressure on the pedals, the chain slipped a tooth or two on my back sprocket, no matter what gear. What can I do to fix it? (it has a Shimano Deore derailer from 2005).

  Chain slipping every second rotation
Posted by: Guest - 07-18-2008, 10:44 AM - Forum: Chain, Chainrings & Sprockets - Replies (1)

Every second turn of the crank chain tension slackens and crank jumps, like chain is trying to catch up on the stroke.
