Is worth replacing Sora R3000 GS for 105 5700 GS

pinchez

My wife as recently taken up cycling and bought her first road bike last year - Specialized Allez Sport E5 which came with Sora R3000 GS, Axis Brakes and wheels. I’ve already replaced the Axis wheels with Mavic Aksium Race wheels which she’s pleased with but I’m toying with the idea of swapping over my 105 5700 including 105 brakes and 5800 crankset which I currently use on my Zwift bike (think Sora will be fine for Zwifting) the only expense I’ll incur is for 2 full sets of cables and possibly bar tape but is it worth the effort?

even though the sora is much newer, the 105 will still be slightly better quality and durability overall, unless its really worn out in which case stick with the sora

It’s worth the minor cost for the exercise itself. Plus your wife will notice you’ve made an effort to make sure she’s got the best bike possible. Everyone’s happy.

The 105 5700 came out in 2010 whereas the Sora R3000 is the current model. Might not be a lot in it except styling and durability - but that depends on how well used the 9yr old components are

I'd just swap the brakes (definitely better) and the chainset (definitely lighter). The rest of it will be a lot of effort for an extra sprocket and little else.

I have both (in fact 5700 on two bikes) - The years haven't been kind to 5700, it requires more effort to shift so apart from it's 10 speed I wouldn't bother.

Thanks guys, the 105 5700 came with my 2013 Canyon Roadlite AL 6 which is now my Zwift bike, I did replace the chainset with the 105 5800 last year just to make it look a bit more modern! as I was using it as a winter bike at the time. Essentially it’s all in excellent condition and changes gear very smoothly. I quite like the idea of just swapping over brakes and chainset as it will give the bike a bit of a lift without much work or spending money on cables etc.

Jeez buy her a proper group set. Less of this re purposing of trashed junk

hey! dont live in a throwaway society, weve only got one planet you know, not everything is about money
reuse, repair, recycle, replace.

If it were me I would let her serve her apprenticeship on the Sora then when it starts to wear move to something better, I doubt she needs another gear or the feel of a better groupset and will go through poor (user) changes, maybe falls or bike falling over, all the things we go through in our first years.

I have Sora on my Whyte gravel bike and have been amazed how good it is and through the years had 9-speed Dura Ace, 10 speed SRAM Rival, 10 speed Ultegra and currently on various bikes I have Sora, DA9000, 9-speed Campag Record TI, 10 speed Veloce and 11 speed Chorus. They are all good so for me if she sticks with cycling she can make a choice later amongst all the mechanical, electronic and Hydro choices when it's all more intuitive.

maybe replace the brakes, or at least put decent pads in.

If it’s not aero with deep section carbon wheels and 28mm tubeless it’s a death trap filling rattler anyway
