Limer alltid dekkene selv. Ikke fordi jeg vet at det er bedre, men fordi jeg er tryggest da.
Fant frem en gammel diskusjon fra et annet forum (på engelsk):
http://biketechreview.com/forum/1-genera...fo-extreme-tape---
Using Al Morrison's data, 0.00260 for Tufo tape versus 0.00239 for Mastik, an extra 8.8% rolling resistance. That's a cost of 2.06 J/kg/km. For example when climbing a 7% grade with total mass = 70 kg that's the equivalent of an extra 200 grams carried up the hill.
Yesterday I did the Mt Diablo Hillclimb (we climbed only half the hill in the time trial) which gained 590 meters in 10.0 km. I used Mastik. If I averaged 270 watts, and I weighed 55.9 kg, my bike was 5.5 kg and my equipment was maybe 1.5 kg = 62.9 kg, then that's 1295 J / 270 watts = approximately 4.8 seconds it would have cost me.
It would be interesting t o see what fraction of the riders that would have cost a place in the overall standings. I'm guessing around 25%.
4.7 seconds in a time trial is a big price to pay for maybe 10 minutes of time spent applying glue. in contrast, at my threshold of $3.50/gram saved (which eliminates most carbon bars and stems, for example, as well as virtually all "SL" frame upgrades) it is an effective cost of around $630 (using 62.9 kg).

Da får en vurdere selv om en synes det er verdt å krangle så mye mer om dette... Forskjell på rullemotstand kan måles, men det er opp til alle og enhver om en synes det er mye eller lite forskjell.
