Oh, and i dont like that shaved stem, thats a no, no. :roll:


I agree.

I'm going to use a Pedalsoft stem and the 21mm 135gm Tufo tires.

Also, I can't use those cranks, they only come in 172.5mm length, too short for me. But I'll get close (1/2 lb) to the weight :twisted:


that tire is not suitable for road use, only indoor or track, plus it has a lower tpi. what crank will you use?


FRM CU2 180mm.

I know it says indoor or track, but I don't see a problem on special event wheels (Spada Winium). I also have a set of Spada Carbon Aero's (38mm rim) coming, those will have the 215gm tires.


how about elite jet 160 g :wink:

The 160's are only 18mm, too narrow for my tastes.

They show them on the Tufo NA website...cool if they have them (the lighter ones are backordered).

i have been using the btp carbon clamp for over a month now. it's svelte at 6.5 grams :), and surprisingly, the seatpost has not slipped. i am using an extralite 'the post ul'.

back to off topic again here, but i'm a little frightful of the btp carbon clamps for my ergo levers. i feel the carbon part of the clamp is super strong, but the strength of the alloy thread and nut is questionable. having a good portion of body weight reliant on the strength of an alloy thread / nut combination is a worry, particularly if one climbs out of the saddle a lot. i opted to keep the stock ergo clamp setup, and forgo the weight saving in the name of safety.

if btp would use a steel thread piece in the clamp, this would work much better. the alloy nut would be fine threading onto this.
