I’ve just fitted a lefty and it turns out my 6° stem was already flipped, so I need something with a higher rise; preferably carbon, but not that bothered.

Any clues what brands to be looking at for 20 – 30° rises?

I’d avoid carbon stems, look at Syntace, I have their “strong one” and it’s 105g with Ti bolts. Race Face, Easton?

Specialized do one which is adjustable using a shim. The S-Works one is reasnable light. Apparently you can adjust the rise using a shim to suit the rise you need. I think they go up to 24 degrees.

Don’t Leftys have a weird steerer diameter?

Nope, they just look **** weird 😀

Using a lefty for all kit = regular size

Cheers for the reply’s, I’ll look into those mentioned

The KCNC Arrow has a 17° rise/drop and is pretty light.

Bontrager Race X Lite come in 17.

Riser bars?

I’m assuming he’s trying to get low, not high? Could be wrong! If so, yes, risers.

Ritchey have a wcs 4 axis with a 17° drop

Hope do a 35deg rise.
Like hens teeth though.

You want one of these behemoths, like my comuter.

Correct. Thinking about it I *might* just be able to squeeze the stem in below the top clamp if I can find a suitably low stack headset top cap/cover thingy.

I found this; it scared me

If it’s for a Lefty then look at the Leonardi ones as they come in at minus 20 and are made for the OPI system. I think qwerty stock them
