I have a 26" alum mongoose on the frame their is 2 cracks where the handbar mounts is this factory warranty???

There should be no cracking in the frame if the bike has not been dropped or crashed at some stage which has then resulted in the cracking appearing.
If the bike has not been abused and the warranty is still current and not expired then you can make a warranty claim if you have the proof of purchase .
Read the warranty terms and conditions first which should have come with the bike documents. If not available, the warranty detail is probably published on the manufacturer's web site.

The better bike manufacturers using very good quality frames normally offer a long warranty on the frame. That is not the case for all the cheapie bikes which most people tend to buy.

The frame of my bike is cracked where the seat post goes into the frame.

You'll need to take it to a welding shop to have it properly repaired. Look at how much a similar "used" aluminum bike frame cost, then use that as a gauge to set a cost limit. Say for example a similar used bike frame cost $100 from a bike shop. If the welder charges $80 or more, then you might as well spend the extra $20 and replace the cracked bike frame instead of getting it welded. Of course, you'll need to take the parts off the cracked bike frame and transfer them to the used bike frame, assuming you know how to do it yourself. If you need to pay a bike shop to do the job, then having the welder repair the crack is cheaper.

I have an old 12 speed racing bike with the shifters on the frame.i wish to either have thumb shifters on the handle bars or end bar shifters but i cant find either,any suggestions please

You haven't looked hard enough. eBay has everything. Unless you have a Campi drivetrain, go with Shimano or Suntour if you can find them.

But they're 'spensive.

I recently acquired an old '84 Cannondale road bike (before they had model numbers) that had all original Suntour 2x6 with downtube shifters on it. Now it's a full Campi-Ergo-equipped 2x9 with FSA compact carbon crank, aero-bar mountain climbing road rocket.

Is it possible to fix a crack in a bmx bike frame or does it have to be replaced?

A ggod welder should be able to fix the cracked frame. Be sure the frame is straight. Sounds like a headpost crack, very common a BMX.

I'd like to raise my handlebars a little on my cannondale f400.

Getting Riser Bars or simply flipping the stem over or getting one with a different rise and reach might give you the added height you need. If you LIKE the handlebars, the stem is the best option as most new ones come with front loaders (detachable front caps) that allow replacement without stripping components off one side of the handlebar. In minutes a Bicycle Shop could swap any number of them onto your bike for you to try.

Manual needed for Cannondale r300 bicycle. Don't know what year it is.

Look around and

What exactly are you needing instructions for? Most bikes are just static frames with a bunch of aftermarket (Shimano, for example) stuff hung on them.

Everything on a common bike is found on just about any other brand of bike and the individual components are usually documented at the individual manufacturers' websites.

"How-to" procedures are all over the internet.

Bicycle recommendations?After many many years of not owning a bike, I've decided I want to get one, not only to keep in shape, riding around town, and on trails (gravel, not hard-core off-roading), but...

I have the Cannondale T2000, best bike I have ever owned. -6TR2.html

If you have an REI store near you, they have a great bicycle shop, and carry the brand Novara, here is a little article about Novara: html?cm_re=NovaraHP*Top*Novara_Story

If the Cannondale is a little out of your price range, my second recommendation is the Novara Safari, which has a really nice handle bar configuration. y?storeId=8000&catalogId=40000008000& productId=47968753&parent_category_rn=450 0921

Both of the above recommended bicycles are considered touring bikes or hybrids. They are very comfortable and easy to use.

Whatever you decide on, make sure you get something with trigger shifting, it really makes a difference for ease of operation and unlike twist shifting, which you accidently knock your bike out of gear when you hit a small bump.

Also, make sure you get fitted for a bike at a bike shop. It makes a world of difference to have your bike properly fitted for your frame. A good bike shop will offer to fit you, then suggest you come back in a couple of weeks for adjustments and to tighten the brake cables.

This is really important, make sure you have a proper fitting helmet. My helmet saved my life. I can not tell you how important it is to have a helmet that fits properly and that each time you get on your bicycle you check the straps and make sure that your helmet is secure.

Changing shifters on my Trek 1400

Of course it can be converted to anything you want - at a price and with some effort. I recently converted a vintage 1984 Cannondale road bike from 2x7 Suntour downtube to full Campi 2x9, carbon crank, yada yada. I like riding it as much as any of the other 3 road bikes I have.

I sourced most of the parts for my various bike projects on eBay. If you're looking for vintage or retro, that's where you go. Just avoid buying cassettes that have been 'slightly' used.

Assuming your bike is still an original 7- or 8-speed, and you want to keep it that way, you may have to hunt around for compatible shifters. Upgrading from 7- or 8-speed to 9 may be the way to go, but then you'd have to get a new cassette (minimum) or a new wheel, or it may not fit into your frame's rear dropouts as the axle spacing crept up over the years with the addition of cogs.

Consider all the individual steps conversion may require; and if each requires yet another modification or encounters a dead end, like frame spacing. At retail prices for parts these days it might be more economical to get a new bike. OTOH, there's no matching the satisfaction of keeping a favorite steed active and doing the work yourself.
