Shimano Altus FC-M315 Chainset 7 8 speed Boost

The product arrived quickly and in good condition. I am still to fit to my daughters bike but it was exactly as described and will serve her well racing her road bike this season. Thanks

I'm a great fan of simplicity, and the A2L is about as simple as it gets. It's a 2-speed automatic that changes gear from low (100%, i.e., direct drive) to high (138% or 1.38) at a predetermined speed. For a 700C wheel, it's about 12 mph, and it's slightly less for smaller wheels. I'm getting on a bit, so I'm choosing a 50" low gear, which will give me a 70" high gear. (I've been testing with my regular geared bike and 50" makes the steepest bit of my local ride just about doable and 70" gets me up to a decent speed on the flat bits.)

Of course. having only 2 gears, for some of the time the low will be too high and the high will be too low. But that's the price you pay for simplicity and I know what to expect. I'm building it into an ancient Raleigh Elite which is both lightweight and lively. I'm expecting some good local rides.

This would be perfect for a not-too-hilly ride-to-work bike or for exploring your locality. It would also be absolutely ideal as a basis for a Swytch conversion.

The hub comes with all the fittings you need, so it's simply a case of building the wheel. It's probably better to build it into an existing single speed bike or an old frame with horizontal dropouts. I'm not sure that the anti-turn washers would work with vertical dropouts. You'll have to check that out for yourself.

The price I paid was good and the delivery time short.

I'm very happy with the item and very happy with the seller. So I'm a very happy customer.

Very happy with this helmet. Light and fits really well. Previous Giro helmet would push forwards as I lifted my head up and the front would tip forward - actually gave me headaches. I barely know I’m wearing this one.

V fast delivery too.

Comfortable helmet. Like the rear light on the back. Was concerned about the manufacture date being Dec 2021 (now March 2025) but states that needs to be replaced 3years from purchase date, so all good.

It’s big but it does the job on my 29er when lesser mudguards have failed!

Great, friendly, quick service. Great advice and parts delivered on time

Arrived as expected on time and at a great price. Thanks Sprocket and Gear

Needed replacement hood covers after a crash. They were easy to find on the site, delivery was fast and they hood covers fitted perfectly. Will certainly use again.

Correct spec, on time.

Good price and great service. thanks.

Quick delivery and a quality seat post.
Comfy ride too.

Arrived quickly and the exactly what I wanted

Bike now running smoothly! New chain, new rear cassette and full service and it’s running like new. Guys managed to fit me in when they were super busy and had the bike ready earlier than expected! 5 stars

Like all FSA components, this is a well made item. Providing you have the necessary equipment to fit the new crownring and bearing cups this is a straightforward job. Sealed bearings mean future replacement is simple.

Highly satisfied
