    Which headset do I need to run a tapered fork in a Rize?

    I want to run a 1 1/2 to 1 1/8 tapered fork in my Rize. I am getting rid of the Lefty and replacing it with one of the new 150mm Revelation WCs.

    What headset options do I have? I am based in US so have access to most manufacturers.

    it will be difficult to find because c'dales 1.5 headtube is somehow different from the industry standard (I won't buy another c'dale for this reason).

    Probably you can combine two oe headsets, one made for Rize 4 (a reducer to 1 1/8) and another for Moto (1.5). Talk with LBS, they will order them for you.

    The Cannondale bearings Inner Diameter and stem clamps are 1 9/16", slightly bigger than 1.5. The headtubes are a size that quite a few headsets are made for, they have a 49.5 Inner Diameter. This being said, I'm not sure that the headset that was posted that was for sale from CRC would work. Like I said, I'm not sure. If danridesbikes uses it and it works properly, then it is another option.

    Cane Creek:

    MTBR Review (This review is for the 1.5, the Double XXC is the one that will reduce the Cannondale headtube to 1 1/8"

    Cane Creek at RideThis.com


    Another option which probably works well, but I would only use it temporarily is the problem solvers kit:

    Hope this helps, I think someone will chime in with more headset options.

    Just realized you need tapered...I'll leave the above post the same for informational purposes for other interested.

    Cannondale's Ask Brad section has this for a similar question:

    This comes from the Ask Brad bit of the Cannondale website...

    Hi Brad,
    My old Headshock is getting tired and I want to replace it with a 1 1/8 steerer tube fork. What reducer headset does Cannondale recomend for XC bikes.
    Thanks, Stephen
    Boo to getting rid of the headshok design. Any 1.5″ to 1 1/8 headset will be fine. Don’t forget to get a 1 1/8 stem and get ready for a sticton filled twisty ride! -BRAD"
    Although this is for a standard 1.5 to 1.125, I think the same would apply to a tapered. I think it would work for any standard tapered headset.

    I think the C'Dale is a 1.5" apart from the Headshok models which were bigger?

    So a standard 1.5" tapered reducer headset should work?!

    This is the headset that came on my Fox Talas equipped Rize ( not tapered)

    http://www.chainreactioncycles.com/M...?ModelID=10125

    As you can see its designed to fit right into the cups on the Rize. From the looks of the NC-17 Imperator S-Pro Tapered Headset posted in this thread, it looks like it will not fit into the cups, although i could be wrong!

    I think you are right. I recall my story now. My LBS ordered a regular reducer for me but its cups were too tall and they could not press it in so they had to order oe headset.

    if you look at the manual you can see that but unfortunately there is no sizing. Roughly the internal part is about 7mm.

    Danridesbikes, your did not try the suggested headset

    Interesting and timely post but still not answering my question.

    I have a 2008 Prophet (conventional Fox 140mm fork) and was looking at the same RS 150mm fork as the original poster with tapered steerer. I figured why not get the tapered steerer for the additional strength it could provide but the head set thing is super confusing. I'm thinking I would need 2 seperate headsets to do what I want to do (or just leave my current top one alone since it's already 1/18"), however, I'm not sure there is a lower cup part even made that would go into the Prophet frame (49.6mm) and have the 1.5" steerer diameter bearing setup. I think the Moto uses this but the cup insertion depth is deeper than the Prophet it looks like. I also need at least 10mm stack height on the bottom so forks tops don't hit cables on the downtube. The Cane Creek Double X short would fit but reduces for 1 1/8" steerer as they all seem to do which fit the big CD head tube. Freaking confusing. Yeah I know just get the non taperd fork and it's easy but I love to be difficult.

    Thoughts......

    The 2011 Cdale Jekyll's come with Tange Seiki 1.5", integrated headsets. It might be possible to mix and match the bottom cup of this Tange Seiki headset, and the top cup of a FSA Orbit Z 1.5 reducer, to give you the tapering you need.

    I also noticed on the link below that the pre-production Jeylls have a Cane Creek 1.5" integrated headset, so it seems there might be a few on the market.

    I'm thinking yes it will work with a 1 1/8" fork. The internal head tube size of the Rize like my Prophet is 49.56mm according to the pic. Cannondale sent me. That is the 1.5" standard spec. Here is what they wrote to me

    The Prophet headtube is HeadShok, OnePointFive and 1 1/8 w/reducer compatible.
    A standard 1.5” headset cup with press in and there shouldn’t be any issue or concern with the cup depth.


    I wanted to use a tapered fork and was worried the insertion depth wasn't enough for the 1.5" standard spec size which is 25mm. Outwardly on my Prophet frame it appears as though it might be about 10mm because of the flared sections top/bottom but what CD is telling me you can get a full 25mm insertion depth cup into it. I need an external cup for my Prophet so I can use the Cane Creek XX-II bottom or the 110-1.5 bottom for the tapered steerer tube. Your Rize I have seen both ways using a conventional fork depending on year. Some with an external cup bottom assy. like my Prophet and some and the flush/integrated looking setups on newer Rizes. CD is telling me it will go in so I think it should go in yours as well. I'm gonna take mine apart and have a look inside and maybe you should do the same to be safe.

    Does that help at all I hope?

    If you asking about Rize then no because the headset bottom cup is too tall

    Ummm.....I think your wrong about that. Have a look at this Cane Creek link

    http://www.canecreek.com/AngleSet

    Cannondale uses both lower bearing types on the Rize so either should work. To slacken you can always get a slightly longer fork or try a 650B wheel besides the headset change.

    Here a 2010 Rize with integrated cup lower http://www.cannondale.com/usa/usaeng...RZ-One-Forty-4

    Here a 2008 with an external cup Orbit Z lower (like my Prophet) http://www.cannondale.com/usa/usaeng...26-9VT4-Rize-4

    exactly, the headset is tooo tall. Look at my attachment above (pic 24 on the left). The bottom is very short (about 7 mm) and does not have any flanges (integrated?) so the rize head tube machined to support it. if it would be machined for a normal headset the default one would not be possible install. Alternatively Cannondale provides another lower cup (pic 24 on the right) also with short insertion depth.

    Ok I see what you are saying (and yes my head is spinning at the possibilities here) however....my guess, and this is without taking it apart is CD is not using a true IS machined into the head tube setup but a pressed in low profile semi IS system. I still think a regular 1.5" standard spec bearing cup can be pressed in. I do not know for sure and heck, we don't even know the exact model or year of Rize this guy has. We do know he had a Lefty which means Headshock std which means the 1.5" std spec not IS. The very small flange on the Cane Creek would add just the slightest bit of slack and he wanted more anyway.

    What do you think?

    Its a 2009 rize 3 alum. Im trying to slacken it out a bit to make a super d race bike. I cant get my lefty pbr to feel right. Looks like i will just try to find a 1 1/8th fork with as close to 530mm as i can without going over with the headset cups. Just wanted to keep the front end/ bottom bracket low.

    I like it. I can dial the fork u-turn for different trails (less travel for twisty singletracks and more rocks). The maintenance is very simple. The downside is its weight.

    and I will be honest I'm more XC than really AM rider,,, however I have made some progress in AM direction since I got the Rize.

    any idea if the FSA Orbit Z 1.5 reducer is the one to use when converting to a tapered fork on a 2012 Cannondale Jekyll carbon 2?

    First things first. If your rize is the same as my rz it will have the si headtube. Not si cups. The measurement is 50.8 and it will take the bearings directly into the frame. Some older c dales take a standard 49.6 or 1.5 reducer headset. Not the case if youbhave an.si heatube. There are 3 options. One is the adpaters mostly made by problem solvers that uses a standard 1 1/8 headset. Which suck because the stack height is enormous top and bottom after adapters and headset. Plus small non sealed bearings. The second option is an adapter which presses into the c dale bearing and then the fork presses or wedged into the adapter. The adpters are machined to the tolerances of the 1 1/8 steerer. This uses the larger original bearing so should be the stiffest option. Option 3 is a si headahock reducer headset from cannondale experts website. Which presses an adapter into into the frame then smaller cartridige bearings and mating crown race and top wedge to fit 1 1/8 steerer. There also is reducer headsets for tapered and 1.5 steerers. They use reducer cups and.the 1.5 portion uses a custom bearing to fit the frame and fork. You can also.order any of these reducer headsets from a cdale dealer which can be order from cdale direct. The two adapter options for 1 1/8 are available on ebay.

    Beware of headsets that advertise cannondale reducer as they may be.for non si headtube frames. You need to measure your id on your headtube. If its 49.6 you can use any standard rducer headset. If it measure 50.8 you need an si type reducer.

    Unfortunatley cdale experts is out of the tapered redecer set for si. None on ebay either. I was looking also. You might have to find a cdale rep and.see if cdale has them in stock. Rite now you might be sol until they are back in stock. There might be a supply shortage on them. I was gonna go that route also. You could do a rev fork in 1 1/8.steer with the adpters.that press in the cdale bearindgs. Should be close to the tapered stiffnes.

    confused with this one.
    On Rize manual, it's stated that part KP058, is needed so that a 1 1/8 fork can be use on Rize (Al.).
    The confusion begins when I read in some foruns, users stating that it was installed FSA Orbit z1.5r headset without problems...

    I would like to try a different fork (presently with a Lefty Max 140) with 1 1/8 steer tube diam. and if possible slacken it with a Works Components.

    Question:
    1- Is it really possible to install 1.5 headset (converting to a 1 1/8) on a Rize frame (MY2009, Aluminium)?
    or
    2- The only way to install a 1 1/8 headset on a Rize frame (MY2009, Aluminium) is using KP058?

    Experienced users on the subject much appreciated!
    Thanks!

    1. yes

    2. yes (that i would trust).

    Why do you not want to buy the KP058?

    Also if you want to totally be sure contact these guys directly.
    https://www.cannondaleexperts.com/cr...tion=contactus

    I just converted from 2013 trigger 2 Lefty to 2014 rock shox revelation tapered. I spent a ton of time researching options and i finally went back to the kp205. Dont look for short cuts just go with the kp058.
