Upgrading 8 speed 2300 to 10 speed - Where do I start ??

Postby Tjgoodhew » Tue May 06, 2014 10:47 am

My OH is doing the London Triathlon in August and I wanted to upgrade her bike from its stock 2300 8 speed to maybe Tiagra or 105 10 speed. I rode it briefly yesterday and I couldn't believe how clunky it felt compared to my Tiagra. The front shifting was awful

The bike in question is a Marin Ravenna - http://www.cyclesuk.com/49510/products/ ... -bike.aspx

It currently has a triple but as we live in Essex she hardly uses the small cog so wants to move to a compact double. This will also be easier for me to look after going forward

I am just after some advice and opinions on the best way to do this. I want to try and do it myself even though i am a complete novice. The plan was to try and pick up a full groupset and change everything which i think is pretty much my only option. Is it best to buy new or pick up something second hand ? Has anyone seen any good deals out there that they can point me too ??

The bottom bracket compatibility worries me so if anyone can hep here that would be great.

I also need a bit of advice on tools. I have the usual toolbox with wrench, spanners, etc.. as well as a chain whip and I know I will need tools for the BB and the chain. Anything else ??

You can get a full Tiagra 4600 at Ribble for £240 which includes everything, even brakes.

Or full 105 for £299 at Merlin or Ribble.

I recently carried out a similiar upgrade (viewtopic.php?f=40004&t=12959215 viewtopic.php?f=40044&t=12961464) and I am still impressed by the new groupset.

I would recommend checking BB compatibility and also that your rear wheel is 10 speed compatible.

Toolswise, I was recommended the Jobsworth Kits from Planet X and I will pass on that recommendation, did the job excellently.

Similar to yourself i wouldnt consider myself a total novice and i know roughly how its all put together. How did you actually find it all ?

I didnt think about the real wheel. Altho i do have a spare wheel that is 10 speed so not the end of the world if the stock wheel isnt 10 speed

I am just about to order that toolset. Looks great for the price !!

I considered it a really good learning experience. Hardest part for me was removing the old BB without damaging the threads. My neighbour would say that the cable routing in the levers could be simpler.

The 105 groupset from Ribble came well packed with instructions included with each component.

I plan to use the old groupset on a Winter bike,

Where in Essex are you, happy to help out if you get stuck. Probably just aswell to buy a new groupset if funds allow. dont forget new bar tape, as the old will get ruined taking it off to change the STI's. Realistically this is just over an hours work to swap out the old and put on a new. Get a HT2 BB

Im Leigh-On-Sea. Thanks for the offer - might have to take you up on that if i get stuck :)

So if i get the full group from Ribble is the BB that comes with that compatible with the Marin ?

Bloody hell! It took me almost that long just to put new bar tape on!

I swapped my Daughters Allez from 2300 to 105, took me best part of a day, I'd never earn a living at being a bike mechanic :oops:

Taking the Marin shown on the link from an 8-speed running off a triple chainring to a 10-speed with a compact double will be:

1. Expensive and fairly tricky for the benefit derived.
2. Of limited benefit.

Many of us who have pedalled our way over the years through five, six, seven, eight-speed cassettes and on into double figures have marvelled at the ingenuity but felt relatively little real-world benefit from each technological increment.

The woman in question would almost certainly be just as fast on the bike as it is (but in excellent condition) as she would on the desired upgraded bike, also in excellent condition.

If it's just a smaller outside sprocket or a shorter low gear she wants, then there are gazillions of 8-speed combinations available that would simply fit on in place of the existing one.

My advice would be to get the tyres up to a good pressure, give the bike a good service and replace any service items (cables, tyres, brakes, chain) that are showing signs of going west. And leave it at that. A freshly serviced bike feels just like a new one and often goes like one too.

You CAN make the change you describe, but whether it makes sense for the marginal gains is questionable. Happily, it is your bicycle and your decision so you can ignore me. But I would not do as you plan to do.

Normally I would agree that a bike designed with 2300 isn't upgrading. But; I would say that £240 for a Tiagra groupset plus a toolset which can be kept for other purposes isn't bad in the scheme of things, and gives the OP a good little project to learn about bike maintenance.

This may be more relevant for the workshop thread but one of the things that made we want to change it over for her was how bad I found the front shifting. The bike is nearly new and has recently been into the LBS for its 100 mile service.

Rear shifting is fine but the front is awful. Its a lottery to if it will actually shift. It just doesnt seem to work smoothly regardless of what you do to it. She is relatively new to road bikes and she is just sitting on the middle ring as she doesnt want to try and shift the front. Its been back to the LBS a number of times and they seem to think its fine.

There may be an inherent problem however i have never had any issues like this with my Tiagra compact and am comfortable making minor adjustments once its set initally. It shifts perfectly near enough everytime.

The 2300 with a triple just seems like a combo that doesnt really work and i would rather just avoid the headache and try to make it so the OH is confident with her gear changes which i know i can achieve with the same set up as mine

A friend of mine has a mens marin (2013 model but not sure of the name), has a 2300 triple and its fine. Mine is a 2300 shifter and mech on a compact and doesn't feel much different.

when I first started, mine went way off, and tracked it to the cable jumping the guide under the BB. Spent hours trying to get it adjusted...

You also have the advantage of getting rid of the dreaded button shifters.

I agree about the front shifting with a 2300 triple, it can be pretty bad. I upgraded mine (apart from the chainset/bb) to a bit of a mish-mash of 9 speed ultegra, 105 and tiagra components and it is a lot nicer to use. Didn't make me any faster, though!

It was all quite straighforward to do, even though I knew very little about maintenance at the time. ust take your time with it and use the Park Tools website for tutorials.

A basic 'Bike Hand' tool kit (£30 at the time) was all that was needed, aside from a decent pair of cable cutters - don't scrimp on these, cheap ones won't cut through butter. A bike mainenance stand would have made the job easier, but I managed without.

Given it's only covered 150 miles or so, selling the old groupset on ebay might get you enough for your tools!

Oh, and the wheel should be okay. I think most Shimano type freehubs are okay for 8, 9 and 10 speed cassettes.

If the bike is new, and bought from the LBS - they should be the ones to fix the front shifting!
First thing is to get them to actually test ride the bike in an area where you can watch and have them do front shifting. If for whatever reason they can't fix the shifting, then request that it be changed to a 'working compact double' - at no cost.

Doing a major swap of components can lead to lots of expense, time, and frustration getting everything to work properly.

Remember, if YOU start tinkering with it - then it becomes YOUR responsibility.

Got 2300 on the triban 3 here. Front shifting is pretty good, not as slick as my 6800 ultegra but the difference is not light years different. 105 will be a nice upgrade to the bike for sure.

Make sure you confirm the bb you need before ordering.

Been using my 2300 equipped defy 4 for the last couple of days as my 105 bike is being serviced. Am always quite surprised how much I like it... Have had this front derailleur problem myself, it does seem to go out of synch quite a lot and require fairly regular readjustment. I'm on a compact here...
