Commuting wheels?

Postby Jamesh » 27 Jan 2020, 10:14pm

Anyone care to suggest some commuting wheels for a mate of mine?

Need to be a) cheap, b) reliable, c) durable

I was thinking tiagra / Mach 1?

Cheers James

so 130mm OLN, 8/9/10s shimano freehub, rim brakes, 700C for 25mm to 28mm tyres?

Mach 1 make lots of different rims. I've seen two Mach1 rim models on this type of wheel (from Raleigh?) 'omega' and 'CFX'. Both are OK in the front, but are marginal as rear rims on heavily dished wheels. Omega rims sometimes crack in DS rear spoke drillings and/or anywhere if a wheel is run with slack spoke tension. CFX rims seem a bit soft, but may be less likely to crack as a result.

In any case the life of such wheels will be greatly extended by two simple things

1) stress relief of the spokes and
2) a good setup/service on the hubs, using much more, much better quality grease in the hub bearings and gear oil inside the freehub body,


The hub service might take ten minutes per hub. The correct adjustment is a little free play that just disappears when the QR is used to tighten the wheel in the frame.

With a good setup and some luck wheels of this sort can be run until the rims wear out. However if not set up correctly and thence neglected they might live a short and unreliable life; the weather can get into (unfettled) shimano hubs and wreck them, and machine built wheels can break spokes too.

I’m shocked. Brucey, you forgot spoke count! :roll: :wink:

you normally don't get any choice in these OTP wheels. Actually in Raleigh wheels I think the Omegas usually come in 32h and the CFXs usually come in 36 with slightly less good hubs and spokes. However I think the CFX rim is less strong than the Omega so there isn't likely to be a big difference in the net wheel strength.

FWIW my hack bike may end up wearing a pair of Mach-1 CFX rims before too long, but both wheels will be undished so the rims will probably be strong enough. That's the hope anyway.

pretty much any fixed hub drilled to get some grease inside. front rim - sputnik. rear rim - any.

they meet all your criteria.

Sorry forgot to say 700c rim brakes.

Thanks for all the suggestions.

Cheers James

FWIW I have done some measurements on Mach1 CFX rims.

19.5mm external width
12.9mm internal width
19.9mm overall depth
~2.8mm wall thickness where drilled
No stagger in the rim holes, which are drilled slightly oversize for 14G nipples
weight 490g
Braking surface thickness 1.55 to 1.75mm
ERD 600 to 602mm depending on whether you want the spoke ends flush with the nipple slot bottom or the nipple top.
6063-T6 alloy

Braking surfaces sound a bit thicker than most so should last a bit longer in winter with rim brakes.

that is what I thought, but I would need to measure more of them to be sure it wasn't just a flash in the pan.
