|Fit dilemma, seeking opinions: Risers and Spacers?||mainframe|
Jun 20, 2003 7:01 AM
|I've two bikes, a Lemond and a Look. My inseam is 33".
Lemond- 55cm ctc, HT length 133mm, quill stem, approx. 9cm drop, saddle top to TT is 18.4"
Look- 55cm ctc, HT length 130mm, +5 deg 120mm stem, 5.5mm spacer, approx. 9cm drop, saddle top to TT is 18.4"
Both bikes have about the same reach. I'd like to change the Lemond to threadless to use a carbon fork I have. My dilemma is this:I can't use a standard -7 or -10 stem (without spacers)on either bike, lest I increase the drop 2 or 3 cm. Given the present HT lengths, if 9cm of drop can only be accomplished amongst the interplay of riser stems, spacers, and perhaps a headtube extender, should I be in a 56 or even 57cm frame which would give me a centimeter or two going in? (I think standover would still be OK) Or, am I in a situation to where a custom 55cm frame with a longer HT is the answer?

|Maintaining a 9cm drop shouldn't be too tough. A Ritchey stem, with its tall stem clamp and 84 degree angle will raise the bars about 1cm more than a typical 80 degree stem like an ITM Millennium. A flipped Ritchey (96 degree) would be 3cm taller than an 80 degree stem, but a 10mm longer stem would be needed to maintain the same reach.
My Colnago has an 125mm head tube and places the bars almost 87cm above the floor, with no spacers and a campy heaadset with 25mm stack height (for reference).
If looks are a concern and spacers are needed, I just saw a new cane creek headset that has an extended top section. It was pretty pricey at $120, but it would be an option to avoid spacers, if the flipped stem did not provide enough height. I think it was in my new Colorado Cyclist catalog.
