Is it possible to go from 7 to 10 on a schwinn sidewinder sold at walmart
#1
Is it possible to go from 7 to 10 on the rear wheel. The bike is a schwinn sidewinder sold at walmart. I think it is a freewheel. It's a pretty decent bike, it get's me around without costing too much.

if it is going to cost more than the bike is worth, than I will live with 7 on the back, but the rear gear needs to be replaced one way or the other. I would like to go to 10, but not if it will cost alot of money.

I am mechanically inclined and will do the work myself, but if the more experienced of you could point the way, that would be great.

TIA

First of all you would need a completely new wheel, cassette. chain and shifters. The rear triangle where the wheel is mounted would need to be spread also. So it will cost a lot of money

Secondly it's not worth doing so on that level bike.

Thirdly, it takes more than being mechanically inclined to do any conversion of this nature, as there are a multitude of factors involved, which one needs to research before even starting.

Finally, going to 10 in back will only accomplish one thing - it will put your gears closer together. It will not increase your speed at all.

You need to define for yourself, and then for anyone you ask for help, what you want to accomplish by changes on your bike or with a new bike.

Yep 10-4 to that and in addition you will need lots of specialized tools.

As has been asked whats the goal, and yes it will cost more than the bike is worth. Which may be OK , BUT whats your goal?

Why do you think the freewheel needs replacing?
Never Give Up!!!

Possible yes. A good idea - NO.

If you do all the work yourself, you will need approximately $100- in special tools. If you get a shop to do it, you are looking $100- to $200- is labor plus materials.

You will need:
* new rear wheel; here is a cheap one: http://www.amazon.com/Avenir-Weinmann-Cassette-Compatible-26-Inch/dp/B003RLJJN8/
* cassette: http://www.amazon.com/Sram-CS1091-P-SRAM-1030-Cassette/dp/B008OEA5VI/
* chain: http://www.amazon.com/KMC-10-Speed-116-Links-Bicycle-28-Inch/dp/B001AYOP9M/
* right shifter: http://www.amazon.com/Shimano-SLX-SL-M670B-10-Speed-Shifter/dp/B00GYTO58O/
* rear derailleur, because 10 speed MTB derailleurs have a different cable pull than 5/6/7/8/9 speed derailleurs: http://www.amazon.com/Shimano-RD-M593-Deore-Derailleur-Black/dp/B005DUI6DU/
* new shifter cabling.
* rim strip

In this case I'm going to offer rather pointed adice:

Don't even try to "upgrade" your bike. Do the least needed to get it in decent riding shape. If still not good enough for you sell it and buy a good used bike. You will be ahead in time and money and probably the end result as well, even if the better bike needs some attention.,

And; I would like to offer the specific suggestion of a 1989-1993 Trek 950, 970 or 990.

Hi Cny-man,you said "the rear triangle where the wheel is mounted would have to be spread" why is that?and what would it involve out of interest,thanks.Daniel
And I agree with the above,definitely don't try and do it yourself,its not worth the hassle if your not experienced. I would just buy either a new or used bike that already has 10 speed if you really want that.As I've learnt,the amount of specialised tools bikes require is beyond comprehension, I've slowly brought a lot of them over a long period of time,and there's still lots of things I don't have. A truing stand being one of them,which I don't want to pay £200 for tbh.Goodluck.

Spreading, aka cold setting; is possible on steel frames ONLY. It is the symmetrically widening of the section of the frame that holds the rear wheel.

Truing stand - build your own. http://forums.bicycletutor.com/thread-3834.html

A 10 speed cassette wheel would need more space between dropouts.

not necessarily; many 7 speed mtb have 135mm between the dropouts (OLD) - need to measure before knowing.

The link in my post describes how I built my truing stand. It is almost all just bolt together.

My work table is 2" thick solid particle board core door, with thick oak veneer facing on both sides; on a 2x4 pine frame leg assembly. I made it. The door came from a company that I worked for when they remodeled.

I have built sheds, and finished unfinished sections of houses, including framing, HVAC, plumbing, wiring and sheet rock.

It's not difficult to build a truing stand. This will give you an idea. Mine is totally different but I have no pics of it on my laptop and I'm at work.

That is a dial indicator for checking runout on the rim.
Here is another one similar to the one I built. Not that hard.
