Yet another threaded carbon fork thread...

I know it's been done to death, but a lot has changed (maybe?) since the last one.

My gf has been riding the iro group buy as an every day beater since it first shipped a couple of years ago.
Her nice track bike has a bladed profile design fork and carbon bars (all threadless, of course); she knows the difference is huge, and has decided to go carbon on her iro.
Unfortunately, it's built up nicely as a threadless bike: ultegra headset, cinelli XE stem, etc.

I ride a pretty nice mizuno myself, but they're impossible to find lately.

Can anyone recommend a carbon threaded fork?

I might be way off here but, 1" unthreaded fork + cut to size + chase threads = win?

plausible, except that carbon forks with steel threadless steerers are rarer than threaded ones (if they exist at all).
threading aluminum not intended for threading isn't a good idea whatsoever.

Nashbar?

+1 to not threading a threadless fork. Epic fail will ensue.

kinesis still makes a 1" threaded carbon fork. you may also be able to find NOS easton or profile forks on ebay as they pop up every so often.

Word. I'm pretty sure Nashbar carbon forks are re(/un?)branded Kinesis forks.

Ahh, well that's good to know if I'm ever looking for a carbon fork then.

slightly unrelated, but for what it's worth the iro group buy forks were really heavy, heavier than other steel forks. many nicer road bikes from the 80s-90s had steel forks with better tubing, and there are lots of those (or similar alu forks) available in good shape. many had cast crowns and much shorter axle-to-crown length than the one on the iro, which marginally steepens the geometry a bit as well.

i ebayed a full carbon reynolds for my iro gb, which i love, but had i ordered in 1" instead of 1-1/8" i probably would have stuck with a nice steel fork.

i didn't mean "do they sell threaded carbon forks", but "is there one you'd recommend".

if you aren't sure...

I had a kinetic or kinesis carbon fork with a Cromo Steer tube at one point. I got it from chucksbikes.com but they are out of them. I don't know where you could get one now

Also generally speaking a threadless steel steer tube is not thick enough for a reliable threading, it would snap off with any heavy riding. I seriously doubt a carbon fork with a steel steer tube would have a thick enough steer tube, isn't the point of CF to be lieght weight, a thick steerr tube would negate the benefit.

Also that kenesis fork was a real PIECE, it bent like crazy under load. Be wary of that fork.

that's good to know... i found one for a ben, but i'll steer clear.

i'm thinking nashbar is her best bet. no badges, which is probably best for locking up, and seems to get consistently good reviews.

i'll watch ebay, but at 74 bucks this is probably her best bet. thanks...

I liked it. Its got flex when you want flex and firmness when you don't. I've bombed it pretty hard and not even really anything more than a scratch. Its old and it still looks brand new and I know for almost a fact that no owner of it including me has waxed it or kept up with taking care of it.

That is assuming that bicycle carbon fiber acts the same way as car carbon fiber?
