    Recommend a frame please

    Hi,

    looking to make up a 29er.

    Im after something that will take at least a 36t front ring and have nice short chain stays.

    ideally it'd be steel and ~140mm front fork.

    Any suggestions please. NS Eccentric on CRC is a real bargin atm but itll only take a 32t front ring.

    Cheers

    define "short" chainstays. I have found that BB drop also plays a role in how short the back end of a bike "feels." the more BB drop you have, the longer it feels. so with two bikes with 430mm chainstays, the one with a 70mm drop will feel more planted than one with 50mm drop. so if you can't get a frame with the short CS you want, go for one with a taller BB.

    that chainring clearance is going to be a big problem because it will be almost impossible to make room for it and have room for a big tire. if you look at the Specialized Fuse or the Trek Stache (not steel, I know), that's how the managed the big tires and short stays.

    As it happens, I have a 40t ring on one of my Banshee Primes, and it looks like a 42 might fit. 17.5" stays, and it will take a 2.8 tire. I can see that if the stays were shorter, the ring size would need to shrink along with the stays to clear.

    I gather that "short" for a 29er means less than 430mm or 17" these days

    Nothing set in stone but yep ideally something in the ballpark of <430mm.

    The Honzo geo fits the bill but I believe that is also limited to 32t


    Edit:Sorry, I should have stated hardtails

    29er, steel hardtail, short chainstays, 36t chainring.

    Short in my book is less than 430mm, but since there is no suspension constraints in a hardtail, I wouldnt buy a hardtail with a chainstay longer than 420mm.

    I'm partial to the Guerilla Gravity Pedalhead, 419mm CS, low standover, nice and long, great geo overall, semi custom steel frame, Max 140mm travel fork, made in Colorado. I'm not sure about the 36t chainring.

    $1100 new.

    Edit: Chromag Rootdown, 2018 or newer, not sure on the chainring size. So a 36t chainring is quite large, do you live in a really flat area or something? I run a 26t x 11-46, but I got lots of steep climbs.

    It looks like you can use a boost 2x crankset on a Karate Monkey and fit a 36t ring.

    423mm chainstays, moderate length reach, high-ish BB, singlespeedable.

    Is the 36t ring an absolute deal breaker? Curious, why?

    Many of these frames will take a 34t ring. Do you have a boost crankset? That might open some options.
