Stem ??
 

What stem and bar model do you have on your track bikes? thank,s

Carbon Pro vibe sprint 105mm

What’s up with your punctuation? Are you using a non-standard keyboard or is this just your thing?

Well, currently it is the only weak point of my track bike. Initially, that were the cheap spokes and rear tubular tyre used without sealant until I solved all that successfully.

My bike is steel Tommasini, 1" fork, i.e. it may accept a 22.2 quill only. I dislike aluminium Italian quill stems of 1980s. So I renewed the bike three years ago by usung M-Wave quill adaptor and a standard 28.6 stem. Two years later I broke up the quill adaptor while rode on the street. Then I bought a Nitto NT quill stem 110mm that appeared too flexible. Currently, I use an old AL quill stem, thick, 140mm.

So now I consider either buying Nitto NJ Pro Steel Stem or ordering a custom steel quill adaptor to a local craftsman. However, I am very puzzled of Nittos weight specifications. NJ 140mm, 58-degree is listed 475g, while its 65-degree counterpart I prefer is 375g only. Is this a mistake or the latter is truly lighter and softer?

Have you considered converting your bike to eliminate the quill adaptor? There are several videos on YouTube. Search for "convert a quill bike stem to threadless". This may be more complicated for a track bike unless you go with a steel fork.

Incidentally I used a Technomic quill stem on my old track bike (now used on my basement trainer) for years with no problem.

Thank you 700wheel, I just now became aware of the availability of 1 inch threadless headsets. Recently, I even considered the possibility of replacing current threaded steerer with a longer threaded one so to screw up the Campagnolo cone and then somewhat mount a standard stem above it.

3T ARX stems (I have a collection of the older 4 bolt ones) and BT bars

I am a big fan of Thomson X4 stems. They are technically mountain bike stems, but that is fine. According to the Fairwheel Bikes test, they are the third stiffest stem tested, after the Pro Vibe Sprint and Zipp SL, but at a fraction of the cost.
