Finally, lightweight and short cranks for kids with a narrow Q-factor and a 104bcd 4-bolt layout for chainrings from 30T to 42T. These HUP Kids Cranks are probably the most important component you will fit to your child's bike!

Get it wrong and they lose pedal power and risk injury from crank arms that are too long or wide. Get it right, and they will spend many happy hours in the saddle and maximise their little leg power!

Available in a variety of popular lengths to fit junior/youth riders from age 6 to 14 approx. Compatible with any JIS square-taper bottom bracket, they are cold-forged from 6061-T6 aluminium for strength, low weight and durability.

These cranks are perfect for Road Racing, Cyclocross, Triathlon, BMX or MTB with the appropriate bottom brackets and single chainring, which can be mounted inboard or outboard of the mounting flange to suit chainline requirements.

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect. Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.
