I'm pretty new here (well... I've been read-only for a long time
). I tried to find the right topics, but I couldn't, so I decided to pop some questions in a new one.
Note that I'm 6'1 (187 cm) and weigh 166 pounds (75-76 kg).
1, I have a 2010 Zipp 404 wheelset. Not the CX version, nor the Cylesdale rim version. It's been used for road racing for two years by me and one year (I guess) by the previous owner. Should I use these for CX or not?
2, If not my 404s, what carbon wheels do you guys reccomend for my weight? I've seen some pretty good deals on EC90SLX wheels in good condition on eBay. Or maybe build a stronger wheelset with higher spoke count and say Yishun 38mm carbon rims, Circus Monkey hubs (I'm pretty satisfied with these!) and Revolution spokes (or Competitions? Or a mix?)?
3, I bought my Cube Cross Race Pro with Avid Shorty 4s. After a while I discovered they're not the lightest, so I ordered a pair of Tektro CR720s. Well, they're lighter, but I feel really unsecure with these brakes. I mean, the power of the Avids where superb in my opinion, but with the Tektros -even after changing the stock pads to green Swisstops (rims: Mavic Reflex)-, the power of these brakes (especially the rear) feels like nothing. What do I do wrong? I read that others are satisfied with the braking power. Well, I'm really not.
3/b, If you would have to choose between Avid Shorty Ultimates (I would run them narrow to get more braking power) and TRP EuroX Magnesiums, what would you do if you would want more power? Let's say both cost the same.
4, I found this frameset: http://www.aliexpress.com/item/Hot-sale ... 75633.html
It would cost 600 bucks total (around 670 if I would have to pay taxes and stuff). I would change the fork to a 4ZA Oryx (as in the Ridleys) that I already have and trust in. But what's your opinion about this frame? They told me it's around 1150 grams in my size (58 cm).
5, I'm seriously thinking about upgrading to Ultegra Di2 6770. I'm kind of confused right now... I would only need the right shifter and the rear mech since I run Absolute Black in the front. But I'm confused about the wiring and the junction box and the battery holder etc..
So what parts would I need to make this work? Also, which parts are interchangeable between the 7970 and the 6770 regarding the wiring, battery, charger, holder, etc.?
5/b, I found this: http://www.ebay.com/itm/301014528309?redirect=mobile
What do you think of it? What else would I need apart from this, a rear mech and the right shifter to make the system work?
I think that's it for now. If you could answer any of my questions, I would be very grateful!
