Thats my RST with the drop-bars in the gallery section. Its still very new to me. The weight of it as pictured, bag, small tool kit & pedals, ~15.4 kg. Its a lovely bike to ride, pretty much exactly what I wanted, just slower than expected. The main diff between RT & RST is the frameset. The RST is a nice 853 conical tubing, the RT is a heavier frame. I'd expect the weight diff to be very slight and the RT to feel less sprightly/lively.
The following is my opinion of the RST: much of it would be applicable to an RT also.
The RST is that its a lovely slow bike to ride. I have other derailler bikes, a titanium and a thorn audax: These are both a lot faster even though at 13 kg (also has dynohub) the audax is not much lighter. The speed diff to my derailler bikes was a bit of a shock to me. I am hoping a fair bit of this is the newness of the rohloff, although these will always be a bit draggy compared to deraillers. Put into context, on my local ~50 miler, I could jog round very comfortably in approx 3:15, on the RST, I'm 15-20 mins slower and it feels a lot harder. I dont know if this is helpful: I spec'd 40*16 gearing to give my my nice gear 11. I find that spot on and am riding in gear 10 & 11 mostly. Its very hard work to try to ride fast compared to my other bikes, as richardm noted. It'll carry all I will ever need: I'd happily load > the conservative "recommended limits".
I am very glad I went for the RST, despite the price. Its a lovely ride. Any slower and I'd start to get p1ssed off with it, or change my mindset which I dont seem able to do !
I really like the carbide rims. I dont like the brakeset behind the fork. In fact I think its the worst point on the bike. Light braking causes juddering of the forks just now, I hope it bed in more. I cannot think why you'd opt for a shimano chainset over the thorn. I've only ridden about 500 km on it so far, so all of the above are very much first impressions.
