Trial Questions

[lardo_69]

I would post in "Random questions" but i have quite a few of them.

First if i was to run two free wheels on the hub and on the crank, in effect this would be the same as running a free coaster hub right. Could some please clear this up for me.

Will this freewheel fit on a hub i got a little confused reading the description... http://www.tartybikes.co.uk/product.php?id=398

I have been using chain tugs but they don't seem to be maintaining chain tension. They bend out of place personally i think there a load of crap.

How do people rate snail cams. I have never seen these things before and was wondering how they work. (when did they come on the market just out of interest)

Is running my head set like this okay? (these pictures where taken off a phone at night there a bit crap)

Basically i am running the headset seal cap thing, upside down will this do any damage? it wont fit other wise.

When i pull my back brake it looks like my frame is flexing or is it just the rim moving. Or is it both. Will a Brake booster solve this? I am interested in a "GU" one are they rated.

Well thats pretty much it.

I am sure there was something else, of well another time. Thanks

The brake booster should stop the frame flexing And i think the tensile freewheel is a front freewheel, so it doesn't go on a hub. If this is wrong hopefully someone will correct me.

I'm afraid i don't know the answer to your other question as i'm new but hope i helped

okay i am going to get a Gu brake booster. How do people rate the GU brake boosters.

Can i get a tensile free wheel for the rear then?

[JT!]

On a bike setup, you only have one free wheeling device. You never have 2.

If you were to get a freewheel on the back you would need something like this to screw onto the cranks.

However, if you have a freewheel on the back, you will need a larger cog up front to retain a good gear ratio.

If you have a 16t freewheel on the back you would need a 24t cog on the cranks.

If you have a 18t freewheel on the back (which is the one in your link) you would need a 27t cog on the cranks.

There really is no cheap way of loosing the front freewheel system. Your better off buying the tensile freewheel and putting it on your cranks.

Snail cams are spiral shaped devices that go onto the axle. They rest against a screw which is in the frames dropouts. When the cam is turned the distance from the axle to the bolt in the frame is increased due to the shape of them. They do hold the wheel alot better than chain tugs, but tend to not be as accurate.

JT what is your gearing ratio. Just out of curiosity.

I don't want to know about gearing ratios by the way but thanks for your help.

I want to no if that type of freewheel is going to fit on my rear hub (which is a T-master rear hub). Because its in my price range and it gives good engagement.

This also makes no sense

There really is no cheap way of loosing the front freewheel system. Your better off buying the tensile freewheel and putting it on your cranks.

I have already lost the "front freewheel system". By running a free wheel on the back and a sprocket on the front. And dont try and reply by this is not the norm i dont give a shit about the norm.

I can see you are only trying to help but sometimes i think people underestimate other peoples knowledge of bikes. The only reason i ask these crap question is that i have been out of the bike scene for ages and don’t ride with anyone at the moment to ask.

I think that people have got this validation bullshit to far up there ass and sometimes quick simple replys are best.

sorry for this rant but its true.

running two freelwheels isnt the same as a freecoaster hub. a freecoaster allows you to ride backwards without pedaling, two freewheels would just half your engagment points.

I think that tensile freewheel would fit on your hub (same threads anyway) but I get a little confused as to which way the tensile lockring screws on, one way is better for on the cranks and the other is better for hubs if I am correct, but I cant remember which (or if it even matters)

What size cogs are you using now?

snail cams are very good, they are snail shaped (obviously) the hub axle goes though a hole and the outer edge pushes against a bolt (usually screwed through the frame just behind the dropouts)

as you turn the cam, the distance between the center and outer edge gets bigger pushing the wheel back.

Snailcams have been out since the dawn of time, motorbikes used them, then monty started using them on their frames decades ago.

why have you got the seal upsidedown in your headset? I guess if it doesnt rock and still spins then its ok, but it will let water and grit inside and the bearings will go crap quickly.

frames do flex, thats why there are boosters around, give it a try, should make the brake better too.

(ps, I thought JT's answers were perfectly good)

yea headset is a bit wrong u have 2 bits in the wrong place (i think from the pic) u have the seal up side down and near the top is the bit that should sit on the seal from what i can see that is.
