Can anyone advise on a good lightweight fork expander/bolt+cap... I dont know the proper name for the parts...the gear which pulls the a-head stem down on a threadless steerer(Alu). Any help welcome, PK

What kind and size fork do you have (1" or 1-1/8")? Integrated headset or standard?

1-1/8 ALu, with standard HS.

Brunetti Cycles (Italy) makes a carbon expander very light (I can't remember the weight offhand, but I had trouble ordering from them direct because of the language problem. However, I have discovered that they do have a US outlet now at brunettiusa@hotmail.com

Another source is Andrew at info@cyclinginnovations.com He is the new US distributior for TISO in this country and they make an 18 gram carbon expander. I should get one from him next week. He, however, just left for Asia on business so I don't know if you'll get him right now. Cost was under $15 without shipping.

As far as a lightweight top cap goes, contact poshbikes in the UK: info@poshbike.com They sell a very light (5gm I believe) Storck carbon top cap with a titanium bolt. Fairly inexpensive and the shop was very cooperative. They also have Tune 10 gm. carbon water bottle holders (must be used with Tune slightly concial bottles, but work great)

Good Luck

Thanks for the info. Talking of TISO, have you seen their new rear mech? On TISO web site under news..weighs 183g ... POSHBIKES will be selling at £190, can you see what your contact in the US will be selling them for.

When you tighten the stem, the fork is locked in the right position.
Why can't these parts be removed to save weight for free???
Just glue the cap on?
