My brother has an online shop which does KTMs , primarily frames but he does build them up and sell them too, As a consequence I have a rigid Ultra 29 and an a Revelator carbon road bike.
Not sure what wheels, groupsets erc the come with as standard. The road bike ultegra with Halo wheels and the 29 has Ktm branded wheels and Xt deone groupset.
I really like them both, but , tbh, I havent had a great deal to compare them with so probably not a particularly objective comment.
The revelator 3300 was a quality frame with a poorer spec groupset at a price set at the higher end of entry level (according to the reviews, as a consequence they didnt sell well. My brother bought a load of the frames (which were the same accross the range) in the 3300 colourway and had they have sold well.
This years road models have a disc brake range as well
