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? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Cinlli Pista Stem ... Short or long?

Just about to order a cinelli pista stem (threadless type, 31.8) for my 2003 Cannondale...

I already ordered the cinelli pista bar but can't descide on the stem length...

If this bike were geared, with a normal stem, based on the top tube length, I would use a 120mm stem...

This is a pista stem so the drop is steeper... Also I will spend more time on the top part then in the drops (it's a single speed so the brake levers will be clamped to the 31.8 part)

What size stem would you recommend based on:

1. Proper fit

2. Proper look


Thanks!!

Use the stem calculator:

http://www.brightspoke.com/t/bike-stem-calculator.html

pay careful attention to the stem height and stem reach. Use your current stem as a starting point and compare it to the pista stem. Typically if you go lower, you're gonna want to go shorter if you want somewhat of a similar feel. Of course, you can't be 100% sure about how it will fit until your new stem is installed.

This is so wrong. Proper fit. Proper look. Pista bar with brake. Hands on the flats not the drops. Pista stem.

Stop now.

Ok... Help me out with this one... One of my road bikes is a Pinarello Montello with a cinelli Xa stem.. What is the head tube Abd stem angle?

Also what would the head tube angle be on a cannondale caad5??

Thanks!

Let me go ahead and waste the time of the people who might come after you, since you have made up your mind. If there is a glimmer of listen left in you, let me repeat - stop.

That stem calculator helps if you are trying to (for example) replicate (or deviate from a baseline) a current bar placement while using a different length steerer tube with a different angle stem. For example, if you have a riser stem and now you want a zero degree stem but want to end up with the bars in the same place.

OP is asking a question about a totally different bar placement.

Where does OP like his hands with this road set up? We do not know. I assume the hoods. So, is OP trying to get his hands on the flats of the pista bars to be in the same place as his hands on the hoods of the road set up? We do not know, yet he is asking us to answer the question.

Further, his priorities as stated are fit and looks. Riding the "flats" on track bars pretty much eliminates any potential for "proper" in the fit department. Putting a brake lever on track bars pretty much eliminates any potential for "proper" in the looks department. Which is why I said stop. OP is not heading in the direction of meeting his priorities.

And another thing, I realize that I should go ahead and answer the question - short or long... meet in the middle:

Hi, you make some very good points, thanks for that...

I do get chewed out on this forum quite often for making track style bikes then adding brakes...

I don't like riding fixed but I like having one gear

I think the only way to determine a length is to order one and test it out...

Call around your local bike shops and ask if they have a fitting bike or something along that lines. See if you can bring in your bars. Trial and error kinda sucks, unless you like stockpiling parts.

Cool! There is a shop that may have one... I will investigate to see if they will let me use it

Luckily the pista stem is only $33 including tax and shipping so I will probably take the advise and start a little shorter to account for the drop (instead of 120 I will go for 100 to start)

If this doesn't work, bike shops usually have tons of cheapo stems they've pulled off to help people fit bikes. See if you can go test a couple lengths. They'd probably be happy to if you tell them you'd like to order the stem through their shop. The slight extra cost of buying at your LBS would probably save you in the long run if you only have to order one size in the end.
