Right now, I'm gravitating toward the Raleigh Roker Comp as it seems to check all the boxes for me. Having to do some assembly on delivery doesn't bother me at all; I've got the tools and experience removing every component on a bike. But I was wondering if there is something else out there that I should be considering before pulling the trigger on a Raleigh?
Zurichman wrote:Caliper I love my Roker Comp. If you love the Sram then you are all set. I am not 100% sold on that end of the bike yet. I will tell you my 56 cm bike weighed in at 20 lbs. I bought a Tamland 1 before that. The hydraulic brakes are so much sweeter than the mechanical on the Tamland. I wouldn't buy a gravel bike without hydraulic after using them on my Roker. I know a comparison bike is the Jamis Renegade in carbon but doubt you could get it less than $2000 unless they are having an end of year sale. Good luck on what ever you buy.

Thanks for the info, and nice pics! I'm kinda torn between the 58 (what Raleigh says, based on my height) vs sizing down to the 56 and getting a slightly lower bottom bracket. Do you mind if I ask what your leg length or saddle height is? I'm trying to visualize what the drop would look like with my long legs.

At my end I think that the Raleighs run a little bit big. All my Lemond roadie bikes are 57cm. I am 6 ft. and have a 34" inseam. I have the Roker and the Tamland 1 in 56cm and they fit me. I think that is a personal thing as I have read some like their bikes bigger and some smaller. I am not sure at my end which way that is. I have a Raleigh Dealer really close to me and I went to his shop and no he had no gravel bikes there but had a bike/frame there that was close and I did a stand over.

I hate to be fussy, but is that a 34" pants inseam, or cycling inseam, measuring all the way to the ground?
I agree, their sizes do seem to run big compared to roadie frames. It's messing with my head since the 56 almost seems like it might fit similarly to my current 60cm road frame...

Can I ask why you believe the Raleigh Roker runs big? The effective Top Tube Length on a 56cm is 560mm and TT on a 58cm is 575mm.
When you compare this to a Specialized S-Works Tarmac 56cm=TT562mm, 58cm=TT577mm. for the Trek Madone the numbers are 56cm=559mm, 58cm574mm.
Just curious to hear your thoughts since the effective TT lenghts are all within a few mm of each other.
Thanks

I'm almost tempted to blow up the budget and try a Noble GX5 in 56cm, since that's apparently the same frame designer.

Oh haven't we all been down that road at one point or another.Mark_Landsaat wrote:
Well, I can assure you that it is the same frame designer, because it's me.
I hear you with regards to stack, that was done on purpose to create a more upright position. If you have the stem flipped down without spacers you should still end up with a considerable amount of saddle to handle bar drop.
Also you have to be careful when you are just looking at reach numbers. Reach doesn't take into account what happens behind the BB. The seat angle also has influence on fit. A steeper seat angle reduces cockpit combination and a slacker seat angle increases cockpit combination.
With regards to the 56cm and 58cm The difference in reach is only 3mm, but the seat angle on the 58cm is 72.5 degrees and the seat angle on the 56cm is 73 degrees. The slacker seat angle on the 58cm will make the cockpit combination bigger. I have a feeling that the 56cm would be to cramped lengthwise.
Let me know if that helps, or if you have any other questions.
Also, what's your current saddle height in mm from center of the BB to top of the saddle? I can set up a theoretical fit in SolidWorks for a Noble GX5 and post the screenshot so you can look at the numbers.

In terms of me, I set my saddle about 800mm from the BB along the seat tube. Definitely interested to see what that looks like. I've also got a lot of leg and less torso. Without getting into numbers overload, the (im)famous Competitive Cyclist fit calculator gives me a 56-57.5cm top tube and 60-64cm seat tube for results if that helps with frame sizing.
I've gotta say that with the tweaks from the Roker, the 56 Noble is very close to the numbers I measure off my paved road bike in terms of stack, reach and ETT.
