MuddyMike Posted November 27, 2014 Posted November 27, 2014 Hi guys, I am building a really decent bike for my son. I am tired of looking for decent kit for kids so building a custom bike raiding parts of bikes in the garage, the hub classifieds and the net. I am almost done but now looking at the final gearing for the bike. I am thinking of going 1x10 for the sake of simplicity for him. I have the new Deore rear derailleur with clutch. I was thinking 32 front, I currently have a 11/34 cluster but don't know if I should change that to a 36? He is 9 years old so the races (20km) he does won't exactly require him to climb any particularly steep climbs. Or should I stick to the 2x10?? The final bike should be close to the 10kg mark, I hope. Any advice please.
MuddyMike Posted November 27, 2014 Author Posted November 27, 2014 Lol, 1x10 to future proof it for 12 months!!!
PeterF Posted November 27, 2014 Posted November 27, 2014 Gauteng is flat, put a road cassette on, 11/25 should work. Just kidding, put on a 11/36, a 9 year old's muscles are still developing, he needs all the help he can get.
Guest Smimby Posted November 27, 2014 Posted November 27, 2014 Look at the restrictions the have in road cycling and apply similar rule
marko35s Posted November 27, 2014 Posted November 27, 2014 Gauteng is flat, put a road cassette on, 11/25 should work. Just kidding, put on a 11/36, a 9 year old's muscles are still developing, he needs all the help he can get.This.There is a fine line between building them up and possibly harming their growth.My eleven year old absolutely destroys me everywhere (climbing, descending, cornering, everything) but if I was to take away some gears it would be for the sole reason of slowing the little whippet down.
popcorn_skollie Posted November 27, 2014 Posted November 27, 2014 If he is 9 then shouldn't it be 1x9?? And a 44 on the front? i chukkled twice http://www.nsmb.com/wp-content/uploads/2013/11/OneUp-Components-42T-Sprocket-green-cassette-front_4_08ab7fb0-9c7b-4e90-ae27-4de8498e1b95_1024x1024.jpg 32 ring upfront10 speed cassette with 42tooth replacement sprocket like in the pic.He'll be lekker fast. Up and downMost 9 year old's still on 24 inch wheels.So a 26 to him will be like a 29er to us.Who am I kiddingHe's probably taller than me.
shaper Posted November 28, 2014 Posted November 28, 2014 stick with 2x10 as he is still growing and developing. Being 2x10 he will also develop good gear management from both the front and back, better to learn whilst still young.
MTBc Posted November 28, 2014 Posted November 28, 2014 Think that 1x10 will be good, 32t with an 11-36 should be easy enough for him
Nicko Posted November 28, 2014 Posted November 28, 2014 Not sure if he will have the necessary power to push 1x10? :/ If there is a reasonable hill, you need to have a decent pair legs, I battle with my 1x10, but I'm not really super fit!! I would probably stick with 2x10 for now
MuddyMike Posted November 28, 2014 Author Posted November 28, 2014 mmmmm, decsions decisions...... 2x10 11-34 or 1x10 11-36...... maybe I should just try both and see what works for him.... The crank has gone in for surgery......very interested to see how this works out.
MuddyMike Posted November 28, 2014 Author Posted November 28, 2014 Yip XS 26er, ZTR alpine UST wheels, 2015 Deore 10spd drivetrain 150mm crank, Ritchey Superlogic flat bar. He needs to grow a bit before 29 is on the cards......
