WTB Youth bike parts to replace my son stolen race bikes

Hi all, I am trying to rebuild a bike for my son that races U14 and we just had 4 bikes stolen from our shed including his cx bike and road bike (cannondale caadx size 44 and a hupcc size 44 too).
I am after a 48t chainring 130bcd
cassette 16t up
10speed chain ( I can probably get this new if noone has one)
shimano ultegra pedal spds
10speed tiagra shifters shimano r5700?
Bottom bracket shimano hollowtech
Set of wheels in good condition with 10speed hub
I have a small frame I can use and few other bits
That is what the mechanic ask me to source so he can put it together.
I am based in SE London but I can travel around all areas if it works.

If anyone can help and have some bits unused to sell please PM me

Thank you

Sorry to hear that. Got some pedals that might be of use -
Ultegra 6600 SPD-SL pedals
Cosmetically worn but functionally v nice
£15

Shimano R-540 SPD-SL pedals
Worn but working fine
£5

I am SE London too so collection/delivery possible.

Great, thank you send me some pictures if you can please,
I am at HHV quite often and tomorrow at Crystal palace crits, so let me know if nearby, thanks

DM if interested. Cheers. Somewhere near CP or collection from Beckenham would be fine.

Pretty sure I have a youth cassette in my spares box. Shimano fit, 10 speed

I have a spare HT2 BB as well

Got some battered but functional 10sp tiagra shifters you can have free from Hither Green.

I have some Shimano 105 5600 shifters, they're in very good nick, and a front mech too, if you're interested?
