Hi,
This is my first time on this subreddit. I have the hardest time figgering out what I should purchase. Last year I rode a Merida Reacto 6000 Ultegra 11spd 2023 ([https://www.merida.nl/racefiets/reacto-6000-glossy-black-matt-black/2023](https://www.merida.nl/racefiets/reacto-6000-glossy-black-matt-black/2023)). I like to be aero. I don’t have a bike at the moment, since this bike was a lease bike via work and I changed jobs.
Now I am looking for a new bike, and I have chosen 3 possible bikes:
\- Specialized Tarmac SL7 comp 105 di2 ([https://www.specialized.com/be/nl/tarmac-sl7-comp–shimano-105-di2/p/257114?color=396143-257114](https://www.specialized.com/be/nl/tarmac-sl7-comp–shimano-105-di2/p/257114?color=396143-257114)), available at my local vendor.
\- Canyon Endurance CF SLX Ultegra di2 ([https://www.canyon.com/nl-be/racefietsen/endurance-racefietsen/endurace/cf-slx/endurace-cf-slx-8-di2/2739.html?dwvar\_2739\_pv\_rahmenfarbe=TQ](https://www.canyon.com/nl-be/racefietsen/endurance-racefietsen/endurace/cf-slx/endurace-cf-slx-8-di2/2739.html?dwvar_2739_pv_rahmenfarbe=TQ)) available on the website
\- Isaac Boson 105 di2 and For Six Crd carbon wheels ([https://www.isaac-cycle.com/nl\_NL/p/fiets-boson-mineral-white–105-r7150-di2/65070/configurator/.eJxtkDEKwzAMRe\_iOQVLlizbVymZiguB0JYmW8jdKxdKhZNNw3tfX9rcstbXhSi6srmlzvW2Ts-HK1cWBD\_uww-QBtynea3vpY2I4EqK6BtivMhBrJc6D0Q9iInC4CDJd2bsQjghoAnJh3asyB9gfwCIvAWgr5FRVwv7pDUyuyIxh\_4UH5BMBvYZqGsFwpmXjBd6D\_TbgkwnnhiP-qP0txkMwEfAM4\_7\_gE3y4u0.vQtbXj16mbxvzkL3vruJsAQnHXY/](https://www.isaac-cycle.com/nl_NL/p/fiets-boson-mineral-white–105-r7150-di2/65070/configurator/.eJxtkDEKwzAMRe_iOQVLlizbVymZiguB0JYmW8jdKxdKhZNNw3tfX9rcstbXhSi6srmlzvW2Ts-HK1cWBD_uww-QBtynea3vpY2I4EqK6BtivMhBrJc6D0Q9iInC4CDJd2bsQjghoAnJh3asyB9gfwCIvAWgr5FRVwv7pDUyuyIxh_4UH5BMBvYZqGsFwpmXjBd6D_TbgkwnnhiP-qP0txkMwEfAM4_7_gE3y4u0.vQtbXj16mbxvzkL3vruJsAQnHXY/)), can be delivered in less then a month to local vendor
All are in the same price catergory. Specialised has the best carbon (R10, 2023 version). Canyon is known for it’s price quality, good Carbon (R7 I think), also upgrade to Ultegra. Isaac is a lesser known brand for all IU know but they ensured me it’s carbon frame is stiff enough and made for competitive use, also upgrade with nice carbon wheel set. They couldn’t give me a comparison to Specialized or Canyon since “specs of their carbon is unknown to us”.
As a rider, I do more flat surfaces with minimal climbing since I live in flanders, but also like to go for more climbing from time to time to our well known Flemish Ardennes (Kwaremont, Koppenberg, etc…). Bike has to fit both. I like to go fast, but all bikes seems to be quite aero. Would ride it on Mont Ventoux later this year.
What should you go for if you had to make my choice? Anyone that can compare Isaac used carbon to Specialised or Canyon? What is your experience with Isaac bikes?
