so I'm building a single speed road bike for my daughter using an old Apollo frame. My question is I know that there are road bikes for kids (my daughter is 9) that are 153 mm but I cant source any that size...however I found the Bulletproof's in 150 and 155 mm. so I'm not sure which to choose from as I fear pedal strike at 155 and 150 may be too short already, but i can't say for sure since I left the bike at the LBS to have the wheel redished.
any suggestion? should i be worried the 155 is too long?
thanks for the help...and yes I'll post a pic once it's done
