Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer?

Need some quick crankset advice

I have a english iso taper 68x107 bb.

On somewhat of a budget and lazy to buy tools that i didnt want to replace my bb and so i am just buying a crankset.

Im down to two choices from CL.

used miche primato for 75$, no pics, have to see it to determine condition
new vuelta pista for 40$ plus he will deliver

Im leaning towards the miche, but is the 35$ more worthwhile? Anyone have experience with both of these cranks?

Do either one of those cranks use a 107 bb spindle? If so, use that.

If the Miche Primato is in good/fair condition, I would definitely go for that. I know it for sure uses a 107 ISO BB. $75 is a good deal depending on the condition.

Hi all

The bike was bought by my dad new when he was in his teens and after minimal use it just sat in the garage for most of its life, then I sore it just hanging there with dust and spiders webs all over it. I cleaned it up, got a new set of tyres and did 50-60 miles a week on it. the bike has not been in used for about a year now and i have decided to turn it into a fixie bike. i have seen this frame and bike on ebay for 60 so if someone want to restore this bike its not hard. i wanted to bring it into the 21s century and make a fun fast bike that i can use for commuting.


the frame and forks where rubbed down smooth and then had 4 coats of primer and 6 coats of montana baby blue paint with 1 coat of varnish. the frame and forks are sweet.

the head set, seat post and cranks where polished and all the bearings cleaned and re greased. this bike is a classic i know that but i will never sell this so it is my project and it will be past down to what was called a f**king teen to ride ha

As stated before, it uses a 107 ISO bb, make sure the one you have is ISO.

More about square tapers.

Update: Was not able to buy the miche, was too late. sold already.

So i got the Vuelta cranks. So i greased up the taper and cranks, bolted it in. It feels secure and all but how far do i pump that bolt in? It felt secure and it was somewhat hard to bolt in the nut already halfway. But I muscled it in almost all the way to the big difference in width, maybe 1-2mm away.



Is that supposed to be where the cranks go or did i go too far? I fear I may have done something wrong. It has a really good chainline right now but the ring is on the inside so it doesnt look so pretty.


Also, kind of offtopic but, why is it better to have a 55/20 gear ratio instead of 44/16?

First of all, you should only grease splined spindles, not square-taper. Using grease increases the risk of pushing the crank arm too far onto the spindle and deforming the square crank/spindle interface.

Secondly, what is that supposed to be a picture of? The spindle? I want to get it tattooed on my ass.

Its the square taper of the bracket. Its near the end. Theres that little curve where the taper gets alot thicker.

That's what is supposed to prevent your crank arm from going on too far. Greasing it is counteractive.
