QUICK RELEASE CONVERSION
Thread started by
JOKER at 10.6.09 - 11:24 am
I have a really nice quick release type cassette wheel, and I'm about to throw it on my new Surly 1x1 Polo Bike which has track style rear facing dropouts. Im told with enuff torque a quick release skewer will slip in those dropouts, and believe you me I can provide plenty of torque. SO my question is; is there a simple conversion skewer that allen wrenches on, or better yet an E-Z way to switch to a nice 15mm bolt on axle for this wheel?
PARLORBIKES where you at?

since you're using a cassette wheel with track drops, are you planning to run it as a single speed or are you using a fixxer?

ummm.... No and No.... It will be freewheel with the full cassette on there.

nothing to worry about.... honestly... unless you have cheap quick release.

by the way... im assuming you have a chain tug or two from your 1x1, right?
You can usually switch to a solid axle, but it depends on the wheel... so its not something that can be determined from you post.
Just use the quick release, and if youre spacing out the rear cassette... just dial it in straight and call it a day.
Get the QR tight though

What about chain tensioners?

Not gonna space out the cassette, I need a choice of cogs on there, I never know which I'll use until I get to the polo court Im gonna play on (I travel for this quite a bit). I thought about a chain tensioner, but it looks like they're all made for thick bolt on axles. Or have I not looked hard enuff? Also the guy at the LBS whom I trust said he could slip his Quick release skewer on similar dropouts easily.

IM confused a bit...
You want a cassette on rear freehub... okay
BUt... youre not using a derailleur... okay
JOKER: THINK-- CHAINLINE
You only really have two usable Chainrings, so you really only have a 2-speed option
just spaced out the rear free hub, with two different cogs.
Base the size of the rear cogs, on the size of the chainrings you're using.
If you plan on using all the cogs of the cassette... you wont have any torque to play with, because you'll keep throwing your chain off...or out of gear...
Does this make sense?

I see yer point. I cant seem to get big enuff cogs sold solo for the cassette, and the ones I have already are all stuck together except for the small ones I wont use. Also on a different setup similar to this I didn't throw my chain, and that really isn't the issue im asking about here.
JOKER10.6.09 - 12:32 pm

thats fine...
the answer is yes, you can use a quick release without issue...
but you added to the question.. and i was trying to help you out...
You can get cogs easily in 20t... they come even larger... how big do you need?
also.. its most likely that the ones stuck together (unless its a screw-on freewheel)... are only bolted together... you can separate standard cassettes.
maybe im misunderstanding.

Yeah its a trip trying to figger this out. The gear inches i need depend on the length of the court and the weight of this not yet complete bike, thats why I wanna run the full casstte until I figger which cogs and chainrings Im gonna use. With this Polo, it really comes down to trial and error. Or perhaps Im just totally obsessed with building polo bikes...
JOKER10.6.09 - 1:16 pm

all you need to do is by one of the like 8-packs of cogs... Sinz makes a pack
cheap... and just hopefully you have a few chainrings to play with...
once you find the RIGHT ratio,,, buy nicer stuff

NICE! All the single speed kits I saw had an 18 or 16...
Any suggestions on the nicer stuff?

surly... they make great cogs...
but too much money if you dont know the size you want to use.
I honestly think... for the 1x1 frame, and the little ive read about the setup you want to do...
is to just run a 2-speed. 4-tooth rule and you dont need to remove the wheel to get another gear
Use your mid/outer chainring + 2 single speed cogs in the back. The trick is to be able to use the same chain for both... 4-tooth rule....or or else you can just carry two chains with you... there are options...
I can guide you to nice equipment... but again it can be a waste of money if you dont like the ratio.

Just curious what makes the SINZ ones crappy do they wear out fast?
Basically I'm running 36-24 on a big court and 36-27 on the short courts and that seems to be as all purpose as I can find in the dozen or so cities Ive played in so far, with the grabby, 26" low pressure tires. I like having the full cassette so hopefully I will be able to switch down to the small ones to ride around town when Im not playing.

if it slips you can put on a QR tighter by taking an adjustable wrench and put it in the QR lever for more leverage. just be careful not to bend or break it.
larsenf10.6.09 - 1:49 pm

quick option..
since your gearing is very very low...
use all 3 chainrings in a triple chainring crankset
granny gear, can get you pretty much the same ratio as the 36-24 / 36-27
granny gears are usually 22t (so ill assume for now thats what you'll use)
low chainring gearing: 22-14/ or 15 (like your 36-27)
mid chainring gearing: 32-20/ or 22 (like your 36-24)
mid chainring gearing: 40-14?
You would need multiple chains most likely... but that might be fine... since you'll know the court...
hopefully you get the idea.. sorry its brief

i should have noted... i based the ratios on the ease of finding smaller single speed cogs, rather than using cogs from cassettes (less likely to slip)

DUDE BRO thanx fer the help. Actually I can only use the mid and granny gear, the outer one is a bash guard, has to be. I was avoiding the granny gear cuz I was worried about slippage, especially under high torque, high spinnage. BTW does anybody have a link for a gear ratio calculator that factors tire width and diameter, so I may further this?
MD2 if u roll by Polo I'll have a beer for you...

cool... thanks... ive thought of joining... just hard to find time. Maybe one day.
the granny gear is fine...
just to help illustrate... think about how flatland, vert BMX riders use small chainrings.
If youre lucky and you like toying with bikes...
heres how to get a third fixed gear....
use a 26" mtb wheel with a disc mount... and mount (by drilling) a cog and bolt it on the mount.
or
try using a small amount of spacers...just enough to clear the chain width... and add another cog to the freehub... the sinz, Dimension style BMX cogs are great for this...
Your commute is less likely to skip, than needing to make quick moves on the court... i wish i had photos... but basically the sixe difference from the 20t and say a 14t, is enough that you can pretty much line up the 14t up to the middle chainring (though its off a little bit)... blah, blah, blah...
Let me just say this....
check out the DOS ENO freewheel by White Industries..
its supposed to line up to the mid and outer chainring, but it doesnt... there is room to play with... but its not as dangerous because your not riding fixed.

Joker...
yo, hard to focus today at work... anyhow... unless Im a complete retard... I should have guided you this route:
http://www.universalcycles.com/shopping/product_details.php?id=20611
If your 1x1 does NOT have a derailleur hanger, try using the above one (or similar options)...
Then you can just run a 1x9 setup, with a rear derailleur.
Now you dont have to worry about chain tension, or the axle moving.
I just setup my SS MTB as a 1x9 (see pic) -- i dont know why, i was just bored.... its pretty fun... but I only use like 3-gears, so its a bit retarded on the street... but i thought... shit.. that would be perfect for what Im thinking you want to do....

word... So if only a couple of teeth hit the chainrings and cogs no big deal? I thought it *could* be more prone to slippage than what I had with the bigger gears. In polo we spinnnnn...
thanx for the advice, and yeah a bunch of people at polo have asked me about 'Fixing' a cog onto the rotor mounts :p

"So if only a couple of teeth hit the chainrings and cogs no big deal?"
Not sure what you mean??
I think youre reffering to the amount of chain wrap (how much chain engages with the chainring/cog teeth)?
Very good.
Its an issue, but with a 22-15 / 14... you should be good... you're not riding up hills. Its flat...
Just make sure the tension is good. But overall, yes, its very good to keep in mind... I dont play polo, so maybe I should claim agnostic on this thread after all.

Naw no hanger... thats why i bought the 1x1... Ive broken 3 shifters and one removable hanger in 1 year of tournament caliber play so I figgered after my bike got snatched at worlds Id buy a frameset without the option and I love Surly. Basically I want it all but I admit I am now realizing I COULD throw my chain, as the previous setup was on a 5 speed (i think) and this cassette is a 7. I plan on only using the 32 or preferably a 36 ring, I'm not sold on the granny gear thing yet as I imagine it'd throw the chainline off even more (the 36 or 32 will only be on the middle of the crankset).

to be honest...
the easiest thing to do is have 3 different rear cogs, and maybe a different front chainring.
When I rode only SS, i use to have to switch out the cog on the rear hub, when hitting the trail, and then when riding on the street.
Its easy enough... but I was trying to make it easier... and kind of playing with the idea....
The granny gears are interesting though because most are not ramped. THey are straight like a SS chainring... Id say try it around town before hitting the court... im almost certain you'll be fine.
In the end, just spend $1400 on a Rohloff Internal hub, and call it a day

Sorry... but you have me thinking... Ive used the granny gear once for SS mtb... it worked...
I just wanted to mention, you can get granny gears at 24-t. That means you can try a 24-18 setup, to mimmick the 36-27 (thats sounds safe, but Ill let you polo skills determine that)... again just thinking about the chain wrap issue.... the 24-t seems to be plenty... and so does the 18-t
http://www.jensonusa.com/store/product/CG295A08-Blackspire+Stainless+Inner+Chainring.aspx
Now you just need the mid-chainring... which is easier: 32-20 ; 34-22 (surly cog)?
Okay..
Ill leave it alone now... but this sure beats talking crap to Snowcone.

MD2 THANK YOU THANK YOU for yer help. Actually talked to the homey at the LBS and he has an axle that can fit the hub, and it ties down with allen bolts. We'll see how it works and put it to the test. But yeah now YOU got ME thinking about the chain line issue. I'm definitely gonna have to test that out but im hoping I can get the chain tight enuff so it doesn't slip off, as that is a real possibility. Also thanx fer that link, Lindsay.
When this gets solved Im gonna post up here...
