    Possible to convert from 4" to 3" rockers?

    I've read numerous references of people switching from 5" to 4" rockers or vise versa but have yet to come across anyone mention going between 3" and 4". I ask because I just got a new-to-me 29er FS, one of those steel front triangle bolted to a Ventana rear jobbies from a builder who will remain nameless at this point, and it sits a little higher than I expected for a frame of its measurements. The builder has suggested I try swapping my 4" rockers to 3" but he isn't sure if it is possible or not. No I have not contacted Sherwood yet, figuring I'd ask here first.

    I am also wondering if it IS possible to switch to 3", how much can I expect the BB height to drop?

    Thanks y'all.

    Because the front tri was custom made by someone who shall remain nameless at this point, it's really not possible to comment on feasibility or geometry changes related to a rocker swap. Your front tri may have very different geometry than a stock Ventana.

    Geo is 74/71.5 and was built *exactly* like Sherwood told him to (his words, not mine) for 4" rockers. Like I said, the builder has brought up the possibility of swapping rockers without knowing whether it's possible or not. Me, being new to Ventana, really have no clue. All I do know is that just a quick search of the first 2 pages of this forum gave reference to several folks swapping between 4" and 5" rockers like I decide which shorts to wear. Presumably any geo change going from 5" to 4" would be similar in magnitude to going from 4" to 3". So maybe I should rephrase my question...for those who have had both 5" and 4" on their bikes, do you know how much lower the BB is in 4" mode vs. 5"?

    No, I'm pretty sure the 3" rockers will not swap. They were specific to the El Patron. Your BB should be 13.75" high with the 4" rockers.

    If Sherwood disagrees with this, let me know.

    Alright alright, I will. But I thought MTBR was for those of us who wanted to do as much research as possible quietly online so as to create the image of actually working while in the office rather than having our co-workers eavesdropping on phone conversations with frame builders?

    classic blunder

    MTBR is for those who want to absorb as much disinformation as possible before succumbing to a phone call and getting accurate advice from someone who actually knows something
