Hi Slowtwitch brains trust. Need some help deciding on race wheel choice here...
Have IM WA coming up which is a pancake flat 2 lap bike course and my first attempt at this distance. Can get quite windy at times and this wind can change direction quite a lot over the duration of the bike course.
I have both a Zipp Super 9 disc and 808 FC, both clinchers, both running 23 mm GP 5000's with latex tubes (can't go wider tyre width as it rubs at the back). The disc has been mainly used for some short course stuff just for the love of it.
I am confused as to what wheel to use.....
On the one hand....the various articles I have read would seem to state that the benefits of the disc may only be 12-15 secs per 40 km which is not huge over the IM distance. It would also mean I would need to carry alternative spare tubes just for the disc as well (ie no valve extenders).
On the other hand I have a read that a lot of people will always use a rear disc when given the opportunity.
I don't trust the numbers being put out by best bike split....
If it helps....am aiming to average around 210-215 watts (just under 75% of FTP) which will hopefully equate to a bike time of just over 5 hours on the day....
Any help appreciated......have not trained on the disc at all but still have time to get a few rides in with it.
