    New singlespeed project_need advice

    This is my first offroad single speed project. Frame was a craigslist steal. Idea is to build up using old parts i have on hand when possible and then later upgrade if I dig it.



    My question is whether I need/should get a new single speed specific crankset. I have two old ones in the parts bin, but both have seen better days and have worn/ground teeth. If I use one of the older ones, I will probably make it a dingle.





    So are either of these worth using? I can't tell if the wear is bad enough to justify a new purchase. If I went new, I would probably get a cheapo dimension cyclocross crankset (I think they are like $34).

    Thanks.

    my first single speed project had a cheap crank exactly like yours and was used for 1500-2000 miles. Never had a problem with it. It doesn't look pretty but it works!

    The problem I see there is the chain rings have ramps and the chain could jump off, plus if you plan on getting a new chain a cog its better to have a brand new SS chainring to wear evenly with the chain and cog , old cogs/rings/chains dont play well with new chains/cogs/rings. BTW if you dont already have a seatpost good luck finding one

    Why do you say that? According to my measurements and Sheldon's website, it should take a 26.0mm post.

    I like Sugino for retro projects



    True the ramps and pins will do you in... a dedicated SS ring is great - or just one with plain teeth.

    X2. I've been looking for a weight weenie seat post in 26.0, and the Thomson is as good/light as it's going to get...so far.

    well that first cranks has 6 botls on the outer ring and 4 on the innner.
    Can GUARANTEE you won't find a non-custom chainring for that puppy!
    second crank's got pinned rings, not meant to be removed (or replaced)

    my advice is to throw that 34$ in the right direction because neither of those shown is particularly nice (or easy to work with down the road) and you're almost guaranteed a decent weight loss with newer cranks.
    34 bucks to drop maybe 1/4 pounds, maybe 1/2? money well spent!
    If steel is real then aluminium is supercallafragiliniun!

    those arent actually bolts , there some sort of rivet. ive tried to remove them before without success, maybe if you had a dremel but really to go custom for something that low end is really not worth it.id go with a 5 bolt crank set, maybe one of these:

    dans comp used to have a really nice set of dotek cranks for 30 buck but i guess they were defective so they dont sell them anymore

    Thanks for the advice. I decided to canibalize a sugino XD triple from another project. I will probably drop the outer ring and put on a bash.

    Next step is to clear coat the frame, as the paint flakes anytime you sneeze at it. I did some touch up with nail polish, but couldn't get the color right. I am going to go shoot for an 80s sparkly effect with the clearcoat to try and hide some of it. Any tips for masking the BB and headtube, other than liberal amounts of painters tape?

    They're not bad frames. I have a 1997 converted to SS with the semi horizontal dropouts tension is easy to get. I got a new crankset from Amazon its a Shimano LX taken from a Tandem. Pretty strong and a nice polished aluminum.

    I'd put money into a new crank, drivetrain, and wheels long before a new coat of paint or a 26.0 thompson post...
