rudi-h Posted July 6, 2018 Posted July 6, 2018 off-topic... this is my "non real" road bike with its brand new wheelset yes, it's disc, it has a 32t cassette and 28mm tyres on 31mm wide hoops BUT, based on my little 20km ride earlier this afternoon after i unpacked the wheels, its hands down the best roadbike i've ever ridden... flamesuit on: i know its not on the couch and sorry for the tribars... i have 5150 coming up, but promise to take those nasty attachments and akward looking seatpost off as soon as I cross the finish line i think i'll keep her!
Butterbean Posted July 6, 2018 Posted July 6, 2018 I think it's easy to sum this whole thread up thusly: If you judge someone else's ride to criticize, you're an Afrikaans box.. Either compliment, express jealousy, or shut up and pray he doesn't trash you on what you think is a sub par bike, (whatever your par may be). All in all, don't be a Richard.

Fat Boab Posted July 7, 2018 Posted July 7, 2018 I need to pull out my metallurgy textbooks but I think you have it arse about face. Steel is more homogeneous than carbon so it absorbs LESS vibration. Steel is fun to ride because it is thin gauge and floppy as hell. That floppy as hell characteristic is what makes steel feel "magical". There's the inherent material stiffness difference ie anisotropic for CF vs isotropic for steel, which can make analytical comparisons quite difficult. Overlay that with how a structure would be built e.g with differing fibre orientations, tube gauge, frame geometry etc, and it gets even harder to 'gauge'. And then consider longitudinal vs transverse stiffness to road noise vs pedal torque. Presumably there's lots of tech stuff been done on this...somewhere? I remember 'back in the day', an Open University (UK) study module on bicycle frame mechanics considering steel vs aluminium. Got to be something definitive now on material vs structure characteristics??
Butterbean Posted July 7, 2018 Posted July 7, 2018 But...You do get crappy bikes....No one said you don't... But if that's all someone can afford to enjoy the sport, then don't be a C U Next Tuesday about it... Maybe if theh have a NOS sticker on it... Then it's okay.

That said given the restrictions of bicycle frame design, restrictions of cost, restrictions of alloys available, restrictions of fibres available I'd still say that "generally" steel is floppy and carbon fibre is not :-)
Grease_Monkey Posted July 8, 2018 Posted July 8, 2018 No chain That is awesome!!! Some smart people out there making some very cool stuff. Kinda makes me wonder what bikes will look like in 25 years time.
Shebeen Posted July 9, 2018 Posted July 9, 2018 Reading various topics and discussions on this site, I've come to the conclusion that real road bikes are dead. Road bikes were all about speed. Comfort took the back seat and the riders were tougher for it. Now we are seeing 1x drive trains on road bikes, rediculously large cassettes and compact chainrings to make climbing easier, big tyres to make the ride more comfortable and disc brakes. What I can see is that road bikes are starting to morph into mountain bikes. If you want a bike with fat tyres, dinner plate cassettes and disc brakes, get a hardtail mountain bike. Let road bikes go back to the their roots as stiff, lightweight speed machines where comfort is secondary to speed and strong legs get you up the hill fast.Going to add to this. I'm surprised to see how many high end mtbs are being used as road bikes. Methinks people have mainly moved to off-road riding for safety aspects, and then instead of having a road bike they just ride their fancy sub 11kg 29er for the odd ride on the tar anyway, gum boots and all.
CAAD4 Posted July 9, 2018 Posted July 9, 2018 All our early riding in the week on tar has been on MTB's for the past few years since one of our group hit a pothole on his road bike and destroyed parts of it, along with his collarbone. Hell that's what Crossmark tyres are for right?
