Since the front derailleur moves up when shifting out and the outer ring is smaller, the chain will most likely fall off. And shifting inwards will wear the bigger chainring since it is not made for changing gears from the bottom right. The bigger chainring has small pins that will make changing gears smoother but the other side doesn't, so you're basically ...

Chainline could be an issue. Cross-chaining, i.e. big ring and big cog or small-small, is bad because it increases chain wear and drivetrain friction. With the large chainring on the outside as it normally is, it’s positioned to have good chainline with the middle and smaller cogs, i.e. your highest gears. If the big ring was on the inside, then when you ...

I've done the chain-setting by hand for a couple days when I was waiting for a replacement front mech to arrive. It worked, but without a FD cage the chain could bounce around and fall off at bumps, like coasting through gravel. Also, setting the chain while riding was awful-risky because you're bent right down to reach your chain. It gets old fast, and ...

Saddle height for new bike setup purposes should always be set relative to the pedal, not the BB center or any other reference point. So yes, crank length makes a difference. Using the ground or BB center as a reference point is convenient for re-establishing a given height after the post has been moved, but not for setting up one bike to have the same leg ...

According to the rule of thumb method of setting saddle height (knee slightly bent when pedal at the bottom of the stroke) the saddle should be set higher if the crank is shorter because the pedal is higher at the bottom of the stroke. Essentially, seat height is set relative to the lowest position of the pedal rather than relative to the bottom bracket. ...

From what I can see on the Token page, you need to select a BB that matches the crank axle diameter (24mm for Shimano) and the frame bearing cup standard your frame has. The Token web site has a nice filter that lets you select crank and BB cup types so I'd let that guide you initially. This is about the most informative page I've found on the myriad of BB ...

The product page you linked to is listing the crank in question as being compatible with Miche Evo Max bottom brackets, which in different types for different frame interfaces. It will probably also be fine with a Shimano road BB, most 24mm road and track cranks are, but that's not being called out as compatible here, so you're rolling the dice a little. ...

TLDR: Miche crank may not be compatible with Shimano external bearing BB. The Miche BB is compatible of course and will very likely fit your frame (but bearing quality unknown, and probably not as good as Dura Ace). If you are going to use the crank with the recommended Miche BB you need to know what frame BB shell width and thread size you have. Majority ...

Bottom brackets are incredibly confusing--there is a huge number of standards, and some of them refer to the diameter in the name, some the width, etc. The compatibility chart for your new crankset lists BSA as an option. BSA uses the same bottom-bracket threading as JIS--which we know is already working on your bike--so that is the correct BB to get. What ...

The axle will probably be too long pushing the chainring too far out from where it should be which is inline with the sprocket. Most track bikes have a rear spacing of 120mm and use a 107mm axle, compared to 130mm for a road bike, and all sorts of axle lengths depending on the chainring manufacturer, but mostly longer than 107mm.

I love this concept, and it has been on my mind for the last few days. A shorter crank would make for easier cruising at high RPM without having to increase your pedal speed. When the torque is needed using the longer crank arm with a slower pedal speed. Gear changing would be done accordingly. And to answer the response given here several times, changing ...

The Wolverine is a road bike (or 'monster cross') not a MTB. The Soma web site says that the rear spacing is 135mm, I assume the BB shell width is 68mm. If that is the case you can run a Shimano road crank and road chain-line. Compatibility between the crank and cassette is not what you need to deal with. Presumably you are either thinking of installing an ...
