V-Sprint Wheels Quando hubs - how to install freewheel sprocket

Hi - I have just received my V-Sprint custom wheels which look and feel superb.

I have the Quando hubs with an 18T fixed sprocket on the rear, can this hub add a freewheel cog to allow it to be a flip flop?

Cheers

yep just screw it on the other side

Really that simple...ha! Sorry, im a pleb and this is the first time ive built a bike! Cheers for the reply pal.

dont forget to grease the threads

And try not to cross-thread them.

Cheers guys...
Also - anyone know about chainline with these wheels and what bottom bracket length is required?

and how to fit a chain haha!!sorry, i am useless! But i will say the finished product should be worth a photo on here, if i don't mind saying so myself!!!

With all due respect, you're building a bike but you don't even know how to put a chain on?

Doesn't everyone have to start somewhere...I can research myself and find out but thought the general fixed wheel community would help...

Yeah of course but building an entire bike without knowing how to change a chain is a big step! Essentially you need a chain link extractor tool. You can either buy one, borrow one off someone on here or if you're in London you can pop over to Mycycle and they can lend, and most likely show you how to use one. Basically the aim is to push the pin out of a link, put the chain on with the desired amount of links and tension then just push the pin back in, but like I say, you'll most likely need an extractor.

JB - agreed, but so far ive not done too bad...ive managed to put my grips on my handlebars!!!!!!
Thanks for the info, I pretty much thought it was as you said but needed a little confidence booster. I assume you tension the chain by getting the desired length of chain then the tension comes from the wheel position within the horizontal drops I.E. pull the wheel back and bolt.... if that makes sense.
Much appreciate your info pal

Some chains come with joining links, so you aim to have an "inner" link at both loose ends so the joiner pokes through both holes (ooh er).

I like chains which use joiners like this one:

You should be able to measure the chainline with a ruler, for a track frame it'll be 60 minus the distance from the inside face of the dropout to the middle of the sprocket. Probably 45ish.

Emyr - yes, i have exactly that with my KMC track chain. Cheers.
So with a chainline of 45mm would the bottom bracket length be 105mm?

Precisely that.

I was going to mention quick links, but I've never had a chain with one so didn't bother!

And like you said, you just slide the wheel backwards in the dropout/remove links to get the desired chain tension. But obviously, it shouldn't be slack if riding fixed.

Guys - thanks alot fo your help... with any luck i will have my fixie up and running this weekend...I will post photos (assuming people are interested!!!) once its complete...
once again, appreciate you help...

So with a chainline of 45mm would the bottom bracket length be 105mm?

Depends on the cranks, doesn't it?

Emry - ye, Ive got a Sturmey Archer crank with a chain line of 43.5mm with a 103mm BB? I will have to measure my rear sprocket and get that chainline and work from there at a guess.

Well yes, the cranks and don't forget the chain ring. But it's a fairly decent indicator.

What frame is it out of interest?

Sorry it is a crank set.
its a Dolan Pre Curds FXE in matte black without decals...

pre turds?

Oops...Cursa sorry.

Couple more questions if you would..
Chain tension: do you require chain tensioners, i cant seem to get my chain as tensioned as id like... ive been told you dont need to?
Rear Sprocket:- is this liable to "slip" when new... when i apply pressure on the crank with my hand (ive not got any pedals as yet!) and stop it from turning it seems to slip.... is this the sprocket and will this tighten up when i ride it or do it need tightening with a tool?
Cheers again...

You'll want to retighten the lockring after your standing starts have tightened the sprocket on.

Cool, thought so as this happened with my other fixed the first time i went on it...for one horrible moment i thought it was the bottom bracket slipping!!!
Cheers Emyr, again!
