Hell fire. Thanks for the replies. Didn't expect so much response tbh. Plenty of food for thought here. To respond so some comments...
What do you do with a bike? Transport, daily shopping, carting stuff about, toy for weekends. Not many bikes will do all of the above. Most importantly get something that fits correctly and you generally get what you pay for.
Difficult to tell, as you say.
I'm not clear what it is you want to achieve. Comfort? Speed?
I'll double quote as my answer should hit both.
I don't get on the bike to go from A-B. If I did that then I'd either be walking or driving.
I get out on the bike as a form of exercise which I tie in with going to quiet (as much as possible) areas - which means most of my cycling is back roads. I look out for climbs as I like to throw a few in. I'll be going for some kind of speed/time goal, whether that's an overall mph average or hitting various Strava segments I'll have earmarked for the ride.
But I don't want to be able to average out 20+mph if my bones are rattling with the rough ride. Likewise it's no good feeling like I'm floating on a cloud if I can't break 10mph & everything is sluggish.
Apologies for answering the question by probably not answering it.
as your not supposed to lock your arms i cant see an issue without seeing you on a bike
I don't think I lock my arms, but maybe I do without knowing. Maybe I grip too tight (though I've tried altering hand positions which involve no gripping at all).
I have a nacked elbow full of metalwork and do ache if in the same position too long. In this regard road bikes work fine for me due to the ability to shift about hand positions.
Interesting, especially with a few saying the same there about the various hand positions.
Second hand market may be worth a punt so that if it doesn't work out then megamoney hasn't been spent.
For those in the south asking where I'm at too - Lancashire.
Also few comments coming in on the bar ends. I'll look in to that for sure. Thank you.
