    Wheels 27 inch vs. 700c, is one really better?

    So I have a 1980s Raleigh Technium that I am converting to single speed (fixed/freewheel hub), I can get either a 27 inch wheelset or a 700c wheelset from my LBS. One shop said that the 27 inch would be a inferior quality wheel, the other did not mention this to me at all. My question is this, is a 27 inferior to a 700c? Both will be new parts (rims, spokes, and hubs). I feel like the one LBS is just completely against 27s, and wants me to buy a 700c set from them and not a 27 from the other.

    Only thing I've seen mentioned is availability: depending on your location, spares for one or the other size may be difficult to find. I know I would be hard pressed to find anything 27" locally. Maybe the first shop has e.g. better quality 700c rims compared to what they have in 27"?

    Quality has more to do with the construction of the specific wheelset/brand/model and not the size. As you may have noticed, wheelsets can range from $80 to over $1500 depending on quality, regardless of size. That being said, Road bikes are typically 700cc, and mountain bikes are typically the smaller size, although this is changing. A quick google search tells me that Techniums were typically 700cc, which is the size on most Road bikes. I would stick with this size.

    Which did your bike originally come with?

    If it came with 27", I would stay with it strictly so that you would be sure of brake reach.

    Admittedly brake reach only needs an extra 4mm to reach the 700c, but every extra mm of reach means your brakes are a little less effective due to leverage. If you want to move to 700c, be sure your brakes do have the additional 4mm of reach available.

    People get all excited about the extra availability of 700c tires, but frankly, if there is one tire you like in 27", does it matter that there are only 30 different tires for 27" and 3,000 different tires for 700c? I suggest that it does not.

    The tires for 27" are wider than the narrowest tires for 700c, but I think the narrowest tires on 700c are too narrow for most riders anyway. Not all of us should be on 23mm tires. People would enjoy riding a lot more if they would change to more comfortable widths instead of riding what Lance rides.

    I ride 27" on most of my bikes because I ride older bikes, and that is what they came with. The wheel quality is fine, and in one case, I recently had a set built in 27" because of brake reach (cantilever brakes on a touring bike).

    If brake reach is fine for either, then 700c should be fine. However, if it is a stretch, don't drink the kool-aid... stick with 27"

    27" tire availability is temporarily low this summer at both the shop and distributor level as thousands of people are dusting off bikes that have hung in garages for decades to start riding again. These thirty year old bikes often only need new rubber to get them on the road again.

    But you can bet that the tire manufacturers notice demand going up and are taking steps to take advantage of it.

    Thanks everyone...will stick with 27s I think, for braking reasons and I like the tires I have on them now which are new.

    You have been misled by the misniformed.

    622 vs 630 is 4mm in radius that 700c is smaller. This makes NONE jack**** difference in braking power. A change in brake pads will be a much bigger difference than 4mm increase in pad distance.

    27" wheels are easy to find, any shop can order them. There is a much greater selection of mid-high performnace tires than there are for 700c. If you don't care for this, then stick with 27".

    I'd like to get a hold of the 700 cubic centimeter road bike wheels.

    And 26" MTB wheels aren't going anywhere, buddy.
