I am riding a RM vertex 29er. A pretty light carbon bike, XO equiped with some XX, RS sid RL and some light racing wheels. The frame must weight arround 950g.
I have a sponsorship opportunity for next season. Thing is the sponsorship involves some handmade columbus steel frames which are about double the weight of my vertex: 1850g approx.
The weight is a factor for me because im racing a lot and I need a good bike that wont slow me down and be hard to accelerate all the time. The other factor is the steel bike geometry: the TT is 12mm longer, the WB is 20mm longer (big concern?) and the CS length is 12mm longer. I am concerned with the WB being longer, will it make the bike feel much slower in the corners?
I'd get the new bike equiped full XTR and with a fox fork.
Thanks for insights.
I would be looking closely at position. The geometry sounds like it will have a steeper head tube, and slacker seat tube to generate the stated numbers, so you will have to see how you fit on it.
The XTR/Fox combo will also be heavier then the XX/RS combo, so weight will play a bigger factor.
Would you be able to test ride the bike/frame at LBS for example?
MSC Koncept Carbon Di2 - 6955g
Leichtkraft Team Carbon - 6868g.
Can you not move down a frame size to keep it more compact and use the seatpost and spacers to get back to where you are now?
I just can't see the logic of adding 1Kg to the bike and expecting to be as fast and giving them the coverage they want/expect, not going to happen.
here is the "new" bike geometry chart with ym current measure between ()
ST: 406 (432)
TT: 575 (592)
CS: 445 (433)
STA: 73,5 (73)
HTA: 70 (70,25)
WB: 1087 (1087)
HTL: 102 (100)
that would help a lot if you could analyse the measurements. Thanks

Sure a lightweight carbon frame or a lower bike weight might be good for the motivation but i honestly dont see 400 grams in a frame having huge disadvantages.
If you would be ridding heavy wheels or shitty tires i would have more concern. Geometry is something that might a litle getting used to...
I think the main point is that the geometry looks different enough to feel some difference in the ride. Whether or not it the difference in feel is something you get used to quickly or simply can't get on with I don't know!
If it handmade steel surely this is the best material and manufacturing process to get custom geometry... Is that an option?
So either a setback in place of inline or a greater setback post combined with sliding the saddle back if necesary to the limit on the rails.
