Hi All,
New user to the forum here but I don't think this exact question has been asked...
I've been the happy owner of a Triban 500 SE for the last 6 months. Had the back wheel replaced in the 3 month service and now have another problem with it (the free hub has started intermittently slipping usually at very inconvenient moments).
If I bought a set of the new Mavic Aksium wheels (i.e. Mavic Aksium Road Wheelset 2016), these are rated at 11 speed. What would be the best 8 speed cassette to pair with these (do I need to buy any additional spacers etc.). I'd like to keep it 8 speed as a drop in for the current Microshift system. Any chain recommended etc?
Also, I had a go at removing the existing BTWIN cassette using a B'TWIN BIKE FREEWHEEL REMOVER but it didn't fit (couldn't slide it into the splines). Did I get the wrong tool?
Thanks, and nice looking forum!
Tom

Welcome Tom,
That wheelset should come with a spacer for an 11-speed cassette.
Chain - KMC X8.93 served me well.
Cassette - ratios depend on the ability of yourself to ride the terrain you want to. If you are a flats merchant then 12-26 PG850 is good. If hills then 11-28 is favoured by many to provide a lower ratio and a higher ratio than standard but with bigger gaps between changes.
You need a cassette lockring remover not a freewheel remover which is generally for mountain bikes.

Thanks Rocket! Another related question - is the existing (Microshift?) cassette 'shimano compatible'? Another option could be just to keep the old cassette and chain for now, on new wheels but they come in shimano and campag flavours.

If you get the Aksiums they should come with a 1.75mm Mavic specific spacer that you will need to use with the SunRace 8 speed cassette 12-25 fitted as standard to the 500SE. The spacer slides on first then the cassette. As quoted by Rocket you will need to choose the Shimano option for the wheel set.

Thanks guys, I've just put on the new Aksiums using the existing 500 SE cassette and the spacer provided with the wheel. They're running very nicely (despite the large pothole I hit) and didn't even need to reindex/set limit on the gears, so an easy procedure. Brakes needed slackening a bit that's all.

tomt Looking to buy a 500se in next couple of weeks. I heard the seals on the spindles aren't up to much and the weather gets in. Glad I read your post though. This will be my 1st road bike and on a budget. How much did the wheel upgrade cost?

Hi byngo, the set of wheels was Β£135 - not too bad for what you get but obviously a good percentage of the cost of the entire Triban 500 se! If/when you upgrade make sure you get some nice plastic tyre levers. I tried changing mine on the road using the metal lever on my multi tool and made some deep scratches in the rim If you're feeling brave, you could take the lock nut and cone off one side of your stock wheels, carefully pull the axle out and put plenty more grease in each side. Then just tighten the cone by hand until there's no play but doesn't feel rough (this will make sense when you're actually doing it). That may help the wheels keep going a bit longer. The tribal 500 se is a great bike and I hope you enjoy using it as much as I have!

The wheels and tyres supplied with the 500se aren't very good, I changed mine for Aksiums within 2 weeks of buying the bike. If you aren't fussed about colour, Superstar Components have some decent wheels left in their sale for Β£99, with a good guarantee and very quick free delivery. I bought some 30 Elites recently and am very pleased with them. There's still 24mm left. which would give you Β£40 left to buy some decent tyres and inners compared to the cost of an Aksium wheelset. www.superstarcomponents.com/en/clearance-icon-ultra-11speed-wheelsets-2024.htm

Then just tighten the cone by hand until there's no play but doesn't feel rough (this will make sense when you're actually doing it) Just to clarify, you must lock the cone and locknut together tightly with spanners then recheck the adjustment. I find usually it needs to be slightly overtight (you can feel some roughness) before doing this as the final locking loosens the cone slightly. In the past some of the wheels have been overtight and short on grease which has lead to premature wear, it's worth checking them.

OK guys. Thanks for the tips. Got the 500se now. So far so good. Like it.
Update about 10 weeks into owning the new bike....
After riding in very heavy rain one day, decided to check how the wheels were running the day after and they felt and sounded quite gritty.
Cleaned out the front hub and bearings, re-greased and now seems perfect. Rear seemed to feel and sound the worst. After cleaning could feel that the surface of the bearing seat each side of the hub was feeling quite rough and two distinct spote where it felt like there was a depression. Maybe pitting I guess. Anyway, cleaned and re-greased now, doesnt feel as smooth as the front wheel does but I think a pair of Mavik Aksiums will be added to basket soon.
Dreadful how quickly the bearing surface has detriorated. Smacks of sub-standard, cheap metal used as the bearing surface seems to be breaking down from rolling contact with the somewhat harder bearings. (Thats my engineering talk kicking in).
